Fantastic experience: I've been seeing Dr. Peloquin since I've been 18 - 19 just out of high school, he was in early 20s I believe. He did 2 root canals then knowing I had no insurance at that age. He was in Burbank at time moved out to Homer Glen and so did I. I've followed him to every new office now i live in Union Mills Indiana 70 miles away and still make the trip, my daughter also sees him she's 25 and Im 57 years old now. Not gonna quit on him now just because of a little distance! Hes a wonderful man and so is his staff. Thank you Dr. Peloquin Jeff and Victoria

Fantastic experience: I have been a patient for probably 15 years. I could not even think of switching dentists. I see Lisa the hygienist and Dr. Brennan and they are both wonderful.

Fantastic experience: I had Karen the hygienist work on my teeth. Hadn’t had a cleaning in 8 years! But she was fabulous at explaining what was going on with my teeth and getting rid of tartar and stains. I didn’t know that we all get it and why. She was also very personable. Dr. Mark I’ve known since high school and he’s always been honest and good to me as a patient. He’s also taken my kids and me when there’s been an emergency.

Fantastic experience: Was in and out in 20 minutes for replacing my crown that fell out. Dr. Brennan was able to use the old crown.

Nina Pellicci Published on Google

Fantastic experience: So glad I switched to this dental office! I've been getting my teeth cleaning and exam by Dr. Brennan and multiple hygienists for the past 2 years. Each time I have had a great experience. The staff is friendly and the office is clean and well-equipped. Dr. Brennen also does not push unnecessary work. If I stayed at my old place, I would have been convinced to spend thousands on gum grafts for minimal recession. I agreed to go through with one, and it was a painful recovery and something I'd rather not go through again.

John Lyman Published on Google

Fantastic experience: Had my visit to have my teeth cleaned and then a visit with Dr Mark Peloquin on my new implants and some cavities. The receptioist ladies were very polite and accomadating. The cleaning was excellent as the hygienist took her time and made sure all my teeth were cleaned properly. She was very professional and curteous throughout my visit. Dr Mark was also very professional and polite. He answered all my questions on my new implants and any issues I had with thme. Thank you all for your great service.
