OS Dental (Formerly Byron McKnight, DDS): Reviews
Fantastic experience: Dr Olga and staff are the best. The work they have done was painless. They make you feel very comfortable while they do the procedures. So glad I chose Dr. Olga.
Fantastic experience: Very pleasant people and they have more concern for for each person than just dental work
We are All in the Family as far as we are concerned!
Fantastic experience: As always, this office goes beyond to make your feel special! I feel like Byron made a wise choice with his new replacement for us long time clients. Dr. Olga Stepanchenko is excellent and made our transition so easy. Thank you!
Our patients ARE special and we are so happy to hear that you are pleased with Dr. Olga. Thank you for your many years with us and many more to come!
Fantastic experience: Good Morning....This is Laurie... Ann Hinde's daughter and wanted to say that I Am thrilled with how my mom is treated. Abundance of caring and professionalism here!!!.. They are genuinely glad to see her when she comes in for her visit!!!... My mom is thrilled as well and has stated she receives the best of care when she comes in... We all usually dislike going to the dentist but Donna and the whole team make it happy and pleasant... 5 stars for this dental group ♥️
We love seeing your mom! She makes us so happy when we see her. Thank you for making sure she comes to see us. It is always such a pleasure.
Fantastic experience: I would recommend Olga for anyone needing a good dentist. She's not even in my plan but is worth it to me to spend the extra money for excellence. Their whole staff shows concern and are always pleasant, making you have confidence while there.
It means a great deal to all of us that you still choose us regardless of your insurance plan to take care of your dental needs. It is always a pleasure!
Fantastic experience: Dr. Olga Stepanchenko did an amazing job for both my son and me. She is professional, gentle, and very attentive. She made us feel comfortable and explained everything clearly. We are very grateful for her care and highly recommend her to anyone looking for an excellent dentist.
Positive experience: Very thorough cleaning appointment, with one cavity across two crowns discovered. Another uncovered cavity with no further decay. Setting up an appointment to resolve these two areas. Somewhat disappointed that neither of these were discovered in prior cleaning. Different hygienist.
Fantastic experience: Great Dentist. I had an Emergency on Friday when the clinic is closed. Dr Olga helped me right away finding me an Orthodontist that did a procedure on a Saturday. She then followed up with me answering all my questions. I had a great experience when she then had to add a crown. I recommend this office and have been seeing them for over 30 years.
Fantastic experience: Very polite and worked with knowledge and respect, the staff and Dentist gave me the answers I needed to have my problem corrected. Would recommend this place to anyone I know needs assistance.
It was our pleasure to help you out with your dental concerns. Thank you for your recommendation. We look forward to seeing you again!
Fantastic experience: Dr. Olga continues to be the kindest dentist I’ve ever seen, and Shawna (I think is her name) is the calmest hygienist I’ve ever had clean my teeth. I was definitely not stressed at this visit. Thank y’all so much!
Fantastic experience: My 89 yr old mom lost a filling and ls still very independant minded even though she is in a wheelchair and a memory care facility. I googled dentists in the Mesquite area to find one that had emergency appts. AND worked on geriatic patients. Olga was so gentle and talked thru the procedure with my anxious mom and didnt try to sell us on getting full implants like other dentists in the past years. I was unaware of the new type of fillings and sealants available now that made the whole process more bearable for mom. I thoroughly recommend this dentist.
Thank you for trusting us with your sweet mom. It was our pleasure to provide her the care she deserves.
Fantastic experience: I absolutely love everyone in this office from the front office team to Brooke to Dr Olga. They always go above and beyond to make me feel comfortable and welcome. Best Dentist office ever!!
We love our patients as well. Our patients are who keep us inspired to keep providing the best.
Fantastic experience: Dr Olga and her staff do an excellent job caring for me and my dental needs! I truly appreciate the care!
All of us enjoy taking great care of you for all this time. Thanks for trusting us.
Fantastic experience: Huge thanks to Dr. Olga—she is exactly the professional I was looking for. She truly tries to find the most optimal treatment options rather than just the quickest or most expensive one. The whole team is also very polite and friendly. I’m so glad I found this clinic!
We are so thrilled that you found us as well! It was our pleasure taking care of your dental concerns.
Fantastic experience: I have used this dental office for years. Brooke takes very good care of my teeth cleaning and Dr. Olga has done a fabulous job in repairing the terrible worn areas of my front teeth. Donna , the office navigator, is very special at keeping the appointments correct and notifying well in advance if changes must be made.It is always a joy to see the staff . What a great Doctor and staff!!
We are so glad that you feel this way and are recommending us to others to help them to avoid any unplanned problems.
Fantastic experience: The entire office is fantastic and I would highly recommend! From start to finish from Donna at check in to Brooke for the cleaning followed by Dr. Olga for the exams everyone is very caring and professional. They always take in to consideration any anxiety you have and are all very caring and compassionate. If you have any dental anxiety I would definitely recommend Dr. Olga and the rest of her team. Dr. Olga always follows up with me by phone after I've had any work done to make sure everything is going well. Everyone in this office who I have worked with is very kind and caring.
It is so rewarding to be a vital part of your dental care. Thank you for trusting us!
Fantastic experience: This has been my dental office for more than 25 years. The same people are still here doing the same excellent work. If you want an amazing dental experience that you can settle in with for years to come, this is the practice for you!
Thanks for hanging in there with us for all these years. We are looking forward to many more excellent experiences together.
Fantastic experience: I have been using OS Dental services for over a year. Thank you for the qualified work and pleasant service of Dr. Olga and the entire OS Dental staff.
We appreciate the FIVE star rating so much!
Fantastic experience: Donna at the front, Misty in the back, Shay the medical assistant, and of course, Dr. Olga, just unmatched kindness and care. An awesome practice with state of the art service and tools. Don’t ever want to go to another dentist. Thank you.
Fantastic experience: The staff at OS Dental are wonderful. Our whole family has been going here for years and find everyone to be professional, highly-skilled, responsive, and kind. We couldn't ask for more. Dr. Olga and Dr. McKnight take great care of us. Donna always checks in and works with our busy schedules to ensure we have excellent care. We highly recommend OS Dental!
Thank you for your recommending us! We are always happy to accommodate you.
Fantastic experience: I went in for a second opinion while I was having a toothache. Dr. Olga and her staff were very attentive and understanding. Having to be examined while in the midst of a toothache is anxiety inducing, but Dr Olga was very gentle! Her assessment was the same as the one I had already been given, but she spent more time with me explaining my options, why I would need a root canal and referred me to 2 endodontists to do the procedure. She’ll be my new dentist. I felt like I was a patient she was concerned about instead of a profit center!
We are so happy that you found us and gave our team the opportunity to help you. We look forward to taking care of you and your smile.
Fantastic experience: Dr. Olga Stepanchenko and the staff at Byron McKnight are absolutely wonderful The care is outstanding in every way, from the front desk to the hygienists and the doctor. Everyone is kind, professional, and genuinely cares about patient comfort. Highly recommend
Your recommendation is greatly appreciated. Thak you for sharing your experience with us to others.
Fantastic experience: I've been a client for about 30 years - Very professional while being very personal. Highly recommend.
Fantastic experience: I recently became a patient of OS Dental after trying multiple dentists. My dentist of many years retired. I have been very pleased with OS Dental. They have done a great job of explaining what needs to be done and why. All the staff members are professional and helpful.
Welcome to our dental home. We have enjoyed taking care of you!
Fantastic experience: The best dental team in Dallas county!! Very professional, clean and patient. Even texted after 6pm to check in on me and my pain level or to see if any questions. Dr Olga and the entire team ROCK!!!
Fantastic experience: Can I just say... I LOVE my dentist and his practice! Dr McKnight was out of town on my recent visit. I had the pleasure of seeing Dr Olga. So nice, so professional, so caring. I have been going to Dr McKnight for 30 years-ish. I continue to drive to Mesquite no matter where I currently live because the level of care that the practice provides is always amazing. Everyone - Donna, Misty, Dr Olga, Brooke and all the hygenists are amazing. I have tried to find a dental practice closer to where I live but they have spoiled me for sure. No one can measure up. And Dr McKnight is not bad either :)
Time flies when you are having fun! It has been a delight having the honor to help you take care of your smile. Thanks for staying with us all of these years.
Fantastic experience: I was very impressed with my dentist. I enjoyed the explanations given concerning procedure. I have never had a more thorough exam. Now they want me to
Fantastic experience: Can't say enough about the team! Welcome to Roxana! Brooke got my teeth cleaned up quickly and efficiently and showed off the latest of Doc McKnight's toys...a microscope to let you see what kind of critters are hanging out in your plaque! You can't go wrong with this bunch. And it keeps going! Had another great visit last week. Special thanks to Heather who had to work extra hard to remove chemical stains from a recent oral surgery. Can't do any better than with this crew! 18 Years and Going Strong! We first saw Dr. McKnight and his crew 18 years ago. We have been part of his 'family' ever since. The entire crew seems to go out of their way to make sure you are not just properly cared for dentally, but perhaps more important, that you are part of their family. We called early Monday morning to see if they could fit us in for a problem check (my case) and a cleaning (my wife). We were in and out by one in the afternoon, well cared for and completely happy with the care we received. Thanks to Donna, Melissa, Anna and Dr. McKnight for taking care of us!
Fantastic experience: It has been my privilege to be associated with McKnight Dental for a number of years now. Just when I think it could not get better, it continues to improve. I’ve never been under dental care that even came close to what I receive with Dr. McKnight and Dr. Stepanchenko. Together with the staff and office personnel who make up the team at Dr. McKnight’s location, this practice is second to none. From your first contact with Donna to schedule an appointment, you will be consistently impressed with the professionalism that is present in every facet of this practice. I did not think that I would ever get to the point in life where I actually looked forward to going to the dentist’s office, but that changed when I was introduced to Dr.McKnight and his team. Brooke is an outstanding hygienist who has been such a help to me these past few years. Terri is also an outstanding hygienist. I have never met anyone in this practice who was not superb at what they were called on and assigned to do. Professionalism, courtesy, kindness in every manner, and compassion are present in every move this team makes. In case you think I am exaggerating, let me encourage you to come in and see for yourself. I believe one visit will convince you. I am convinced, and my next visit is only four months away. I can’t wait to get there! Bob Ross
Fantastic experience: Dr.McNight and his staff do a wonderful job They are so good,I don’t mind going to the Dentist anymore!

Fantastic experience: The most thorough and careful exam I have ever had. I’m actually looking forward to going to the dentist!!
Our comprehensive examinations are very thorough and detailed to help in your specific dental care. We look forward to seeing you again.
Fantastic experience: I had a wonderful experience! The front desk team was welcoming, the hygienist was gentle, and Dr. McKnight and Dr. Stephanchenko took the time to explain everything clearly. The office is clean and organized and I felt well taken care of from start to finish. Definitely recommend to anyone looking for quality dental care.
We always enjoy your visits. All of us love pampering our patients. Thank you for recommending us.

Fantastic experience: My short term dental goals at McKnight Dental were very satisfactory and fulfilled! A dental patient since Dec. 2014, received nothing less than the utmost of professional care. Cosmetically - excellent outcome, with a health conscience approach. At ease environment & super friendly staff! Visit was great today! Dr Olga’s the best. Two fillings in a jiffy, no discomfort, at ease experience. Great bedside manner to take with you. Assistant Shay was awesome as well. Thanks for a pleasant dental experience. Posted 5/19/25 Recent dental procedure administered by Dr Olga was a joy. Delightful assistant Shay on hand made experience complete. A tooth filling in a jiffy but thorough was without discomfort while meticulously applied. I highly recommend Dr Olga’s professional dental care. Warm environment and very friendly staff! Posted 10/29/25
Fantastic experience: Olga, and her entire office, make sure every step of our experience while there is pleasant. She is so personable and encouraging that it even makes “a trip to the dentist” seem enjoyable.
Fantastic experience: Trouble with tooth and about to have extensive work travel. They got me right in. Always reassuring when that happens!
Fantastic experience: Brooke is soooo thorough and attentive. She gets my teeth really clean and keeps me comfortable while doing it. Not even one little pain! She is AMAZING!
Fantastic experience: I’ve been coming here for years, and Dr. Olga Stepanchenko and her staff always do a fantastic job.

Our team of greats enjoy taking care of our great patients- including you!
Fantastic experience: About seven years ago, I went here to Dr. McKnight and he did an amazing job with over 20 caps on my teeth very beautiful very professional job. And since then I have kept coming here for my cleaning and follow up and checkups, friendly staff!! and now lately a new Dentist name Olga has joined this team and she is really really good and nice and friendly dentist!! I recommend to everyone to come visit this place!!
Time flies when you have dedicated patients such as yourself! It has been such an honor to be part of your new and healthy smile. We appreciate your recommendation.
Fantastic experience: I have been a patient here for 25 years. The office is professional, friendly, and I have always had great results. I would recommend anyone looking for a good dental office to schedule an appointment here.
Thank you for your numerous years of loyalty and trust in us. Your recommendations are always appreciated and will provide your referrals the same quality of care.
Fantastic experience: I had a great experience from the entire crew! Roxana was very welcoming and professional I would recommend anyone looking for a new dental office to Dr.Olga
We agree entirely and we thank you for your vote of confidence.
Fantastic experience: “Dr. Olga is amazing! She placed my crown perfectly — quick, painless, and very professional. I finally feel confident with my smile again. Highly recommend!”
Fantastic experience: Everything was handled very professionally. The clinic has a welcoming atmosphere, and I highly recommend specialist Olga for her attentive and careful approach.
Thank you for recommending us! Your referrals will be provided the best of care just as you experienced.
Fantastic experience: I was blow away by Dr. Olga and her team! They were all so friendly and extremely professional. I’m so glad I found this health provider. I would recommend her to anyone and everyone!
Fantastic experience: Outstanding dental practice! I took my mom there after four years of not seeing them due to dementia. They did an excellent job working with her and made sure she was super comfortable the entire time. Everyone was so friendly and considerate. They got her a blanket to keep her warm, sunglasses to protect her eyes, and talked her the whole way through. They even helped us create a plan for her at home dental care that worked with her condition. The best experience I could have hoped for my mother. If you have a family member with cognitive issues, I’d highly recommend OS Dental!!!
All of us were SO happy to have the pleasure of seeing her again. She was missed greatly. Thank you for trusting us to continue seeing your loved one. She will always get lots of well deserved TLC.
Fantastic experience: Ive been coming to have my dental needs serviced since moving to Dallas in 2021. The staff are so personable and welcoming. The techs know what they are doing and provide great recommendations to keep my teeth healthy. This week my appointment backed up to another appointment that I couldn’t reschedule. When I contacted the dental office they were understanding and gave me thier word they would try their best to move my appointment earlier so I wouldnt miss the next appointment. Well they were successful and I was able to make both appointments! I love this dental office!
....and we just love our patients and it makes us so happy when we can cater to our patients every need. We are glad we could help you with your scheduling conflict.
Fantastic experience: Olga is one of the best dds in all of dfw. She is super caring and does a thorough job of any procedure. I can’t recommend her and her team enough. The front office is also compassionate and caring towards every individual. Dentistry sucks, it pays to go to a place that actually cares.
Thank you for your rating and glowing remarks for Dr. Olga and the team. We pride ourselves in the quality of work we provide with compassion and care for all of our valued patients. It has been such a pleasure taking care of you and your spouse.
Fantastic experience: Excellent dental hygiene care by Shawna! Donna, the office manager, is the kindest, friendliest, most personable individual. We’ve been patients for decades and will be for years to come. This practice is the gold standard that that all practices should strive to meet. Dr Olga and Dr McKnight are excellent in their field and care about their patients. I spent time with Dr Olga this visit. She is so personable, friendly, and encouraging as well as an excellent dentist.
It is ALWAYS such a treat when we get to see you! Thanks for letting us spoil you and spoiling us in return.
Fantastic experience: Wonderful experience from a very nervous (new) patient! I needed emergent care for a filling that fell out, causing a lot of discomfort. I was greeted by a friendly front office and the dental assistant was so kind and helpful at keeping me comfortable. She performed an exam of the problem, as did Dr. Olga who also thoughtfully reviewed my health history with me. This gesture to take the time to go over my preexisting medical conditions, I thought , was very assuring I was in great, professional, healthcare hands. The entire process was all done with such careful communication, and comfort. I’m bringing the whole family in as new patients for all our dental needs.
We are so glad that you found us and gave us the opportunity to help you with your concern. Most especially, we are glad that your fears were put to rest and that you have a great experience with us. We look forward to taking care of you and your smile.
Fantastic experience: I got an appointment right away and was treated very well with professional courtesy. My options for treatment were explained as well as cost of the procedures. Overall a pleasant experience!
Fantastic experience: Thank you, Olga! Thank you to the clinic. Now I can smile. Everything was wonderful. I hope it always stays this way, meaning everything remains good!!!
Fantastic experience: Great experience! Staff is friendly. Service is excellent and Dr Olga is great. She texted me to see how I was doing later in the day!
All of us have enjoyed taking care of you. Thank you for sharing your experience. Mission accomplished.
Fantastic experience: I've been a patient of Dr. McKnight for years and have never been anything other than very pleased with his work and professionalism. He has placed several crowns for me and they have all been perfect. Since Dr. Stephanchenko joined the practice I've had the same experience with her professionalism and work. Everyone in the office, from hygienists, to Donna at the front desk and Misty in the finance office, is a pleasure to work with. Having seen other dentists over the years in Dallas and Philadelphia, I can attest that the exceptional quality of this practice is not the norm. I highly recommend both Dr. McKnight and Dr. Stephanchenko.
Thank you for sharing your confidence and trust in our team. We are very fortunate to have wonderful patients that trust us - such as yourself!
Fantastic experience: I had a dental cleaning and check-up with Dr. Olga Stepanchenko and had a wonderful experience. She was kind, professional, and made me feel very comfortable throughout the entire visit. The cleaning was gentle but thorough, and she took the time to answer all of my questions and explain everything clearly. I really appreciated her warm and attentive approach — it made the whole process feel easy and stress-free. I would definitely recommend Dr. Stepanchenko to anyone looking for a caring and skilled dentist.
Your kind review warms our hearts! We are so happy that you are happy!
Fantastic experience: My family have been patients at this dental office for a few years now. We’ve only ever had wonderful experiences. They are committed to offering exceptional dental care, and making you as comfortable as possible. All of the staff and dentists are wonderful and I can’t recommend them enough.
We love having your family as part of our dental family. Thank you for letting us know that you all have had great experiences!
Fantastic experience: This was the best experience at a dentist that I’ve ever had! From scheduling, to the actual exam was amazing. Dr. Olga is thorough, kind, personable and explains each thing she is doing and what everything means during the exam. Dr. Olga really cares for the patients. The staff was great! Donna was so kind, transparent with pricing, listened and very knowledgeable. I highly recommend going to this office.
We are thrilled that you have joined our dental family and that you enjoyed your new patient experience. Our team looks forward to taking care of you and your smile!
Fantastic experience: I have been a patient of Dr. McKnight for several decades. This is the best dental practice you can find in Mesquite and perhaps even the DFW area. The whole office culture is collaborative, professional, and excellent dental care and experience.
It has been a joy taking care of your beautiful smile through so many years. We look forward to having the honor of providing the excellent care you deserve for many more years to come!
Fantastic experience: I have completed a Crown with Dr. Olga. The office texted me a days in advance to remind me of my upcoming appointment. As a busy working mom, I really value that extra point of contact and reminder. On the day of my appointment, I was feeling anxious. The staff allowed me to listen to relaxing music during my procedure as well as answered any questions that I had before and after my procedure. The staff and Doctor made me feel confident that the best of care was taken to make sure by experience was exceptional. The evening after my procedure, my doctor checked on me to see if all was well (which it was). For all the extra touches that the office gives you, I gave this office a 5 stars. Good job! I also am starting my 18 year old son with Dr. Olga and she already sees my 20 year old son. I plan to keep this Doctor in our family circle!! Thank you to all who have been a part of my families dental experiences!
It has been a pleasure taking care of you and your family and providing all the extra TLC you deserve. We take great pride in our quality of work and caring concern we give to all of our patients.
Fantastic experience: Love, love, love this office! Such great people here!! Dr. McKnight has always been so sweet. All of the staff are very mindful of their patients and show that they truly care. Definitely recommend this office for your dental needs!
Love, Love, Love our patients!
Fantastic experience: I had a dental emergency with one of my front teeth and Dr. Olga got me in same day to start the process of getting a crown and fabricating a permanent one. I am so grateful to her, Amy, and Donna for making the process so easy for something so stressful. Looking forward to coming back in the future for cleanings and normal dentistry, too!
It was our pleasure to help you in your time of need for your dental emergency. We are so happy you found us and look forward to taking care of your smile for a lifetime.
Fantastic experience: I have been going to McKnight’s office for over ten years ago and I have noticed that over the years it has gotten better every time I go. I remember going to the young McKnight over a decade ago telling him about my new job and he seemed glad to hear me out about it. We shared stories and I even helped cut the grass for one of his co-workers in need. Then I met his employees at my job! Today I still go over and get my teeth cleaned and McKnight still comes over and we share stories!! What I’m trying to get to, is that I treat them like family because they treat me and my family like family! That makes me feel great about coming back to get my teeth cleanings done there! From the bottom of my heart, Thank you Byron McKnight and the new Dr. Olga for all the years of excellent service and I hope to receive many more years of the family treatment, great advice and fun story sharing, that I have grown to love. We will see you in 6 months!!!
We feel we have the best family of patients ever! Thanks for sharing your stories and we look forward to many more years together.
Fantastic experience: Been with Dr. McKnight since 1989. He's the best. Dr Olga is now on the team and Dr. McKnight would only hire the best, so now there are 2 of them ! Sadly, my 35 year hygienist is retired, but I've had 2 different ones this year who are excellent. If you are looking for a dentist in Mesquite, this is the place to go.
We are looking forward to many more years together!
Fantastic experience: Always the best possible dental experience! Dr. McKnight, Dr. Olga, and the entire staff are truly amazing, caring, and always go above and beyond every visit!
Our team is so pleased that you always enjoy your dental experience. It is our pleasure to provide the service you and all our patients deserve.
Fantastic experience: I recently visited Dr. McKnight for dental work. I’m so impressed with him and his staff. We actually discussed a dental plan with options. He was very thorough and helpful as he pointed out areas of concern. I’m sooo happy to be a patient of Dr. McKnight!
....and all of us are SO happy that you found us and are now part of our dental family.
Fantastic experience: I was lucky to have found Dr. Byron McKnight years ago. He took EXCELLENT care of my teeth and got them to their healthiest! And now, Dr. Olga S. is doing just the same. They both are outstanding in their field. The entire team is uber knowledgeable, friendly, helpful and caring. I’ll never go to a different dentist office.
Thank you for trusting us all of these years and remaining loyal to our team. We will continue to provide the exceptional dental care that you are accustomed to.
Fantastic experience: Dr. Byron McKnight and his team are truly the nicest, most genuine people I’ve ever met in a dental office. From the moment you walk in, you’re treated with kindness, honesty, and professionalism. They’re incredibly trustworthy and always upfront about everything, which made me feel completely comfortable and cared for. Dr. McKnight is hands down the best dentist I’ve ever had in my life. I can’t recommend this office enough — if you’re looking for top-notch care from good, honest people, this is the place to go!
Fantastic experience: I love it here! There’s no amount of words to say or even express my gratitude these amazing individuals from the from desk(Mrs.Donna) the Financial advisor (Mrs.Misty) and of course how can I not mention the lady with lightest hands in dentistry (Mrs.Teri/Mrs. Olga).All these ladies are beautiful inside/ out and they all make sure you feel welcomed from the time you open the door until you leave! I thank them all so much especially since I was beyond scared when I first started my journey with them all!
Welcome to your new dental home and family! We are so thrilled that you now feel comfortable - now that you found the place where you belong and are appreciated!
Fantastic experience: To start, as you walk in the building it surprises you at how well the office is decorated. The staff meet you as you walk up to the counter. They are there to make sure all of the paperwork is in order or if you have my questions or concerns. The staff is great. Everyone is friendly and makes you feel comfortable and relaxed which is a task for most dental professionals. I was the last to go so now my entire family is getting cared for by this office. Another visit down and another great experience. Again, I’ve never been a fan of getting my teeth worked on but they continue their push for excellence. I was going to say surprise me but now I expect it. Nothing but positive thoughts for the doctors and staff.
Fantastic experience: Dr. Olga provides amazing care and details out all your options for treatment. So very skilled and really makes it her passion to make the work done be accurate AND beautiful. You deserve the best care and this is the office to get it from. Donna at the front is also the BEST!
Fantastic experience: My appointment was a regularly scheduled appointment with the hygienist, Brooke, who I go to regularly. My time with Brooke went smoothly. She is the nicest person you could ever meet. The practice has a new receptionist, Roxanna, who acts like she has been part of the practice for years. She is very personable and on top of things. I would and do recommend this practice to everyone.
Your rating is greatly appreciated to our team.
Fantastic experience: Dr. Olga did a great job and it was all a very pleasant experience with receiving my fillings that were necessary! All the staff was very pleasant as always!
Fantastic experience: Dr. O was absolutely amazing with me! I don’t think I have even felt more comforted and heard at a dentist. I went in for a stress TMJ flair up. As soon as I walked into the office Donna greeted me so warmly as if we have been friends for years. When I was taken back Dr. Os assistant was so nice and warm. When I first met Dr. O she shook my hand and cupped it giving me the confirmation that she cares for her patients. Truly the best experience at a dentist office I have ever had in my life! I have △⃒⃘lways hated dentist because it never fails that I feel the pain or the dentist doesn’t listen to my cues of pain and keeps going. This office didn’t feel like a public clinic all out in the open. It felt private and comfortable.
Fantastic experience: I’ve been going to this office since sept 2024, and love the staff. They are not only professional but also care about their patients. Dr McKnight ang Dr Olga are experts in their field and are great with patients. A special thank you to Donna (front desk) and Terry (hygienists) for making each visit welcoming and comfortable.
Fantastic experience: Dr. McKnight and his entire staff are the best of the best. He was my dentist for several years before, and I've returned to him again because he's simply the best. I moved my husband and daughter to him as well. Others may be a little cheaper, but I'll pay the tiny bit extra for the superior work I get from him, his hygenists, and his desk staff. No more hunting around for the closest dentist. It's McKnight or nobody for us. Adding to this a few years later: Dr.Olga is awesome! This office always has the best dentists, hygienists, and office staff.
Fantastic experience: I visited this clinic and was very satisfied. Dr. Olga is an amazing dentist — professional and gentle. The whole staff is friendly and welcoming. I felt truly cared for. Highly recommend!
Thank you for sharing us with others. We love taking great care of our patients!

Fantastic experience: The staff and Dr. Taylor were very professional, thorough, friendly and attentive to my needs. When I arrived I felt like I was home for the very first time in many years. I applaud their expertise and the attention that was given to me and Dr. Taylor is without a doubt, the best in his field and absolutely adorable to his clients. I couldn't be more pleased. The experience has been a pleasurable one and can't imagine ever going anywhere else. I would also like to add that the care and concern that went into giving me my life back with a brand new smile has been without a doubt the best experience of my life. I was scared and didn't really know what to expect. Dr. McKnight, Dr. Olga, Ms. Misty, Ms. Donna are so genuine in their want and desire to see others feel good about themselves again. They have certainly made my experience a pleasant one. Dr. McKnight is adorable, funny, professional and compassionate about what my needs were. He is definitely a sight for sore eyes and has an uncanny ability to make you feel like you've known him for years. He's gentle, kind and passionate about the quality of work that gives to each patient. You will leave there feeling like part of the family. It doesn't get better than that. They changed my life and my smile. The finest in every aspect. Thanks to all of you from the bottom of my heart. I will forever be grateful for giving me back my smile

They took time to explain in detail my dental health, show me 3D 360degree pictures of my mouth and explain the best steps moving forward. First class operation
Fantastic experience: I had a visit to Olga Stepanchenko. I was delighted with her work. Olga did her job very quickly, qualitatively, all the time asking me about my well-being. During the whole time I had no discomfort at all. She is a very good person and a true professional. Now I am not afraid to treat my teeth, it was a pleasant experience.
Fantastic experience: I’ve been a patient at this dental office for several years, and I can’t say enough good things about the team here.

It’s truly a pleasure speaking with her every time. Brooke is absolutely amazing! She does a fantastic job and is always so attentive, making sure I’m comfortable throughout the process. Her professionalism and gentle approach truly set her apart. I’ve also recently had the pleasure of meeting Dr. Olga, and I must say, she’s a wonderful addition to the office.
