"Best Dental Office"
★★★★★
Absolutely best dental office I’ve ever been to! Super friendly and patient staff, very clean and positive experience overall. I hadn’t been to the dentist in almost 15 years and my hygienist was very pleasant and gentle. The receptionists made sure to clear things with me and my dental coverage so there was no surprise costs. I would give 10 stars!

"Great Collective Group"
★★★★★
The best! Can't say enough good things about Smiles of Groton. We have 4 kids and one of them is absolutely petrified of the dentist. However, everyone in the office is great and he's starting to get over that fear, specifically from the great group of people that work there. Beyond that, it's great to have such a great collective group of people so close to the school system where our kids go.

"Wonderful"
★★★★★
Wonderful wonderful wonderful. After having the most horrible experience at a prior dentist, I found Smiles of Groton caring, gentle and knowledgeable. I had Dr Molly and Chelsea put a new crown on and all was perfect, they both could not have made me feel more comfortable. While I still don’t like going for dental care, Smiles of Groton has made it so pleasant. The best around. You would be negligent not to check them out.
-Lisa B.
"Friendly & Efficient"
★★★★★
Smiles of Groton has been great for our whole family! Even after procedures that we'd prefer not to have (e.g., baby teeth pulled), we're still smiling. Drs. Marc and Molly and the whole staff are friendly and efficient. Highly recommend.
-Julie R.
"Pleasurable"
★★★★★
Who knew that going to the dentist could be so pleasurable. Great people who do their job well with care. Smiles of Groton is wonderful.

"Excellent Quality of Care"
★★★★★
Having grown up in the 1950s with the proverbial dentist from hell, I'm pretty picky. Just had my first tooth extraction, which I was dreading, and it turned into a hugely pleasant non-event - no pain during, really minimal after, and Dr. Marc's techniques appear to be just excellent. Since the Valli's took over Dr. Breen's practice, I have found both to be excellent, and the overall quality of care and responsiveness of all the staff I've interacted with to be just as great.
