See What Patients Are Saying About Our Dentist Near Lunenburg, MA

“I haven’t been to the dentist in almost two years and was nervous about going again. The dentist office is definitely not the most comfortable environment for me. However, the moment I walked in and was greeted by the very courteous and pleasant receptionist Amy, I immediately felt at ease. My dental hygienist, Alaina was also very pleasant and kind. She was so gentle and had a great bedside manner which is super important to me in that environment. The dentist who saw me was wonderful too. I forget her name but she was great. Im actually looking forward to my next appointment in 6 months. Highly recommended.”

“I had my teeth cleaned by Jessica F. and she did a great job. Very personable and it was a pain free experience. I also had 2 crowns done by Dr. Molly and it went smoothly. I would highly recommend this practice.”
