Fantastic experience: My husband and I were among the first of Dr Deleo’s patients many years ago. We were hoping that he would be as excellent a practitioner as Dr Argue his predecessor was. We were more than pleased with Dr Deleo’s expertise, his patient care and approach and his care for his office staff. Dr Deleo and staff continue to provide top notch patient care and support. We have recommended the practice to our family and friends and will continue to sing their praises. And in 2026 continued excellence in care from all staff and my dental health is still A1 thanks to Dr Deleo and his wonderful staff. Dr Deleo is without equal in my many many years of care.

Fantastic experience: Outstanding experience today with Chestnut Family Dental practice. Dr. Jim and dental hygienist Molly were excellent. Very thorough, very educational, made sure I understood my options, their suggestions, the pros and cons, that we could have additional discussions with my spouse if requested. Given that I have some level of 'need' for treatment and care they still left me feeling empowered and in control, with their guidance, on making best decisions together going forward. ~ rk

Fantastic experience: I’ve been going to Chestnut Family Dental for over 20 years, and I honestly can't imagine trusting anyone else with my dental care. Dr. Mercado and her incredible team have cared for not just me, but my entire family, for decades—and now I’ve started bringing my own son here too. That alone should say how deeply I believe in and trust this practice. From the moment you walk through the door, the environment is warm, welcoming, and calming. The front desk staff is always kind and helpful, and appointments run like clockwork—no long waits or feeling like your time isn’t valued. Every single staff member is gentle, compassionate, and truly listens to your concerns without judgment or rushing you through. Dr. Mercado, in particular, is one of the most dedicated and thoughtful medical professionals I’ve ever known. She’s been working with me closely on an implant, and she has shown incredible patience and determination to make sure everything is just right. She has gone above and beyond—pouring in not just her time, but her heart and personal investment—because she genuinely cares about the outcome and about how I feel when I smile. Over the years, Chestnut Family Dental has become more than just a dental office to me—they’ve become trusted partners in my health and friends I look forward to seeing. They take what can sometimes be a stressful or intimidating experience and turn it into something that feels easy, positive, and even enjoyable. If you’re looking for a dental office that delivers excellent care with a personal touch, look no further. I wouldn’t hesitate to recommend Dr. Mercado and her team to absolutely anyone. They are, without question, the best of the best.

Fantastic experience: We love everything about Chestnut Family Dental. Everyone is professional, kind and knowledgeable! We will never go anywhere else! Thank you to all at Chestnut!

Fantastic experience: On my first visit to Chestnut Family Dentistry. Everyone I encountered there was very friendly. The initial exam was very thorough, which I appreciated because I know I have several issues with my teeth. Dr. Mercado asked me to come back in a week or so, so she can present me with some options for what we can do to correct the issues with my teeth. I appreciate it that she seemed to care about thoughtful solutions rather than quick fixes. The dental assistant, Daisy, who did my x-rays and intake was very sweet and very sympathetic to how uncomfortable some of the x-rays can be. I truly appreciated the care everyone took of me. On my second visit, I was just as impressed with Dr. Mercado and her staff. Dr. Mercado listen to me about what bothers me the most, and my fears or reluctance to certain treatments and offered other ideas.. I think I’m really going to like having this as my dentist office.

Fantastic experience: Chestnut Family Dental is simply the best from start to finish . Staff is attentive , courtesy and I always feel heard . I have major dental anxiety and have always had a great , thorough experience ! Dr. DELEO is the best but so is his wife. You can not go wrong with either .

Fantastic experience: Ever since I first went there in 1979 it has been a wonderful experience! After Dr Argue retired, he left it with Dr DeLeo and his staff who are amazing..very professional, kind and extremely supportive! ♥️♥️

Fantastic experience: First doctor of any kind lasted more than 6 months with me. . Dr Marcado is frank about the condition, direction and finances of my teeth. I can truest say 3 words that I have never said. to any dental practitioner- I trust her

Fantastic experience: Dr. DeLeo is an outstanding dentist. Twice he successfully completed procedures that other local dental providers said were not possible. He knows and works with the best providers in the field of NH dental care. His staff is kind, competent and informative. He truly advocates for his patients and is personable and professional. I highly recommend Dr. DeLeo and Chestnut Family Dental.

Fantastic experience: Every single member of the team at Chestnut Family Dental are top notch. So professional, helpful and honest about your dental needs.

Fantastic experience: Everyone at the office is kind and friendly, compassionate and helpful. There is no pressure to do any specific treatments but they do let you know what the benefits are and make recommendations. I never feel judged, even though my gum health is not the best.

Positive experience: I have been a patient of both Dr’s DeLeo and Mercado for more years than I can count! Many family members and referred friends have also received services as I have highly recommended them. I have never been comfortable with dental work and this office knows that and takes exceptional care of my needs when having procedures done. I have never felt anything but empathy and sensitively which is what I need in order to even schedule procedures. From fillings to crowns (leaving the office with my permanent crown and not having to go back!!), and my Invisalign journey - I can’t imagine going anywhere else. Ps…the front office staff and hygienists are also amazing!!!

Fantastic experience: I’ve been with this practice for decades. I started there before I met my husband and had children. My two children then started off as tiny patients as well and have been cared for through the years, now one just went off to college and one is finishing up her driver’s Ed! The Chestnut Family dental team has been through lost baby teeth, pallet wideners, braces, fillings, emergency visits, and wisdom teeth removal. They have seen them grow up, been there every three months for cleanings, making sure X-rays are completed, fluoride treatments are up to date, and making sure my kids have the absolutely best dental care there is to offer. They are kind, gentle, and responsive. I have been nothing but happy with our dental care there! Can’t say enough good things!

Fantastic experience: My cleaning was very thorough! My Hygienist asked all right questions. Dr. Mercado was also very thorough and both providing the best options for whitening my teeth.

Fantastic experience: I highly recommend Chestnut Family Dental to anyone looking for a trustworthy, professional, and caring dental team. Providing great recommendations and personal staff!

Fantastic experience: I’ve been a patient here since I was little and they always take great care of my entire family! They remember things going on in my life to help make me feel personally taken care of by the doctors and their entire team is extremely welcoming!

Fantastic experience: I am now seeing Dr. Mercado for Invisalign which included extraction of an existing bridge and a temporary replacement yesterday. I feel like family at Chestnut Dental and am always treated with the utmost courtesy and professionalism by the entire staff. My temporary bridge looks better than my old permanent bridge! Really looking forward to the end result a year from now! Both Dr. Mercado & Dr. DeLeo are simply the best. The staff they hire and work with are simply the best. Dr. DeLeo has replaced a multitude of inferior dental work for my wife & I. He is a perfectionist and consummate professional - just the sort of person you want performing your dental work. I have been to many dentists in the area over the decades and was lucky enough to be introduced to Chestnut Dental. Our family of 5 are all patients and are all treated with the same care and friendliness.

Fantastic experience: Dr Mercado as always did beautiful work fixing my smile with two crowns in the same day....she is caring and will always be my superhero!!! Thank you Denise Michael

Fantastic experience: I have been a patient for years! Very happy with the entire staff and Dr.s.

Fantastic experience: My visit today for a couple of fillings was great. I was actually a few minutes late, and the team at Chestnut Family Dental called me in just after I arrived. Dr. Mercado and Jessie were great as always. They were all done within a half hour, and no Novocain was required. Dr. Mercado even filled another tooth that was close by for no extra cost since she was right there. I really appreciate the great service from Chestnut as always.

Fantastic experience: Excellent first visit! Staff were very friendly and professional. Very knowledgeable and skilled at what they do. Happy to find them in my home town! :)

Fantastic experience: Today was my first time at Chestnut Family Dental. Like many people I despise going to the dentist and in my case it had been 3 years since my last visit! The kind and welcoming staff and clean and inviting waiting room put me instantly at ease. I had x-rays, a gum health exam, an oral cancer exam, an Invisalign consult, and a cleaning! Every staff member I encountered was gentle and kind and at no point was I uncomfortable. Everyone seemed genuinely happy to be there. I am so glad I found Chestnut and would highly recommended everyone to check them out!!
