What Dental Patients are Saying

What Others Are Saying

“What a wonderful experience! I had an infected tooth that had to be removed on a Saturday. The office manager squeezed me in and was so kind. Dr. Cappello and Kim explained the procedure every step of the way. Professional, great bed side manner. I can’t say enough good things about this practice.”

Susie P. Trumbull, CT

“I can see why they have 5-star reviews across the board! Usually the dental experience is one that I loath, but walking in the doors I was greeted by a most professional office manager and my hygienist (Kyra) was ready for me before I could even sit down in the waiting room. The entire staff was friendly and projected a laid back yet professional atmosphere making it easy to relax during my cleaning. Dr. Cappello was friendly and took the time out to talk to me and create a rapport which was a nice change of pace from my usual experience. Great staff, very clean and updated office! 5/5 would recommend!”

Jesse S. Trumbull, CT

“Finding a new dental practice after relocating can be difficult particularly if leaving a dental practice where you were a patient for 30 years. After some searching, my wife and I decided on Cappello Family Dental. From initially making our first appointment by phone and through that appointment, we knew we made the right decision. Very personable staff from the receptionist to the dental technician and dentist. I was comfortable talking to the technician and Dr. Cappello regarding my dental needs. I left the office with the knowledge that I had found the right practice for my wife and I.”

Hank M. Trumbull, CT

“Dr. Cappello had treated me before at another practice. He went the extra distance then in terms of responsiveness and follow up. My wife and I moved to his new practice as soon as we learned of it. Today I visited him on the same day I called to set up an appointment. And while no one likes visits to dentists, I’m very glad to have followed him and made the switch. He’s a very good dentist and he cares about his patients. I wish him all success and wholeheartedly recommend him.”

Shyam V. Trumbull, CT

“I highly recommend. They are very professional, skilled, pleasant and welcoming. They make you feel like you belong. Mary Lee cleaned my teeth with a magic touch. I felt no pain and left as happy as I came in! Dr. Cappello is very knowledgeable and pleasant. The same goes for the rest of the staff, Kim and Christine.”

Biana N. Trumbull, CT

“Dr. Cappello is an amazingly skilled dentist and someone I would not hesitate recommending to family and friends. I started seeing Dr. Cappello after my dentist retired unexpectedly. He was very kind, personable and knowledgable. I instantly felt as if I had known him my whole life and my discomfort at meeting a new dentist was eased.”

Amy S. Trumbull, CT

“I try not to make blanket statements very often, but I’m going to make an exception here. I never want to go to another dentist or another dental office for as long as I live! MaryLee performed my cleaning and was simply outstanding. It didn’t even feel like a hassle! Dr. Bill and every single one of the staff members at Cappello Family Dental is warm, caring, and inviting! Their office is sparkling clean and easy to find. 10/10 would recommend. I can’t believe I’m going to say this, but... I can’t wait to go to the dentist again!”
