Absolutely loved my first visit. Beautiful new building with looks to be all new equipment. Everyone seemed so happy and very friendly. Left there with a big smile on my face and some nice clean teeth. Highly recommended.

I went in as a new client for a cleaning, and I brought my toddler to get her used to the office before I schedule her first appointment. I was so pleased!! The front desk staff were so warm and thoughtful about how to make the experience useful & easy for my daughter. Michelle was my hygienist, and she was awesome - she explained everything to me in plain English, so that all her recommendations made perfect sense. Dr. Cleary was my dentist, and she was great too. It really was an overall pleasant experience, and I'd highly recommend this office to others!

Wonderful staff! Dental Hygienist, Maureen, and Dr. Comstock talked through everything as they were doing it, which made my first experience at Drum Hill Dental very comfortable.
- Julia V.
Staff was pleasant and attentive. They took the time to answer all my questions. Thoroughly explained my treatment plan. Digital x-rays displayed on a large TV allowed me to see any issues as they were discussed.

This dentist office has great positive energy. After having a different local dentist for nearly 20 years, switching to Dr Comstock at Drum Hill Dental was a revelation. Their tools are modern; communication is clear, treatment is exactly on point. Mostly, I appreciated being heard and treated with respect. I recommend Drum Hill Dental.

Fast, friendly, and quality service at DHD. Clearly well-trained staff and will definitely come back and recommend others to do so too! A true gem among dental offices in the area.
Just switched to Drum Hill Dental after moving to the area and being without a dentist for several years (too long).
Everyone from the front desk to the hygienist to the dentist were all terrific. I am a nervous dental patient... and there was no need to be. The experience was a good one through and through.
Everything was explained well and I am actually looking forward to the next steps.
By the way, the facility is also top notch: immaculate and modern, with state of the art equipment. Based on today, I highly recommend.
