Always friendly and professional

I have been a patient there for over a decade and would highly recommend the practice to anyone. All members of the practice are friendly and seem truly happy to be there. Both doctors are great. I’ve had to go in for dental work twice recently and both experiences were as pleasant as dental work could be.

Kate

My kids both really love your office. Everyone is incredibly kind, professional and personal. We love the small, family office feel. My daughter used to be anxious about visiting the dentist. Last night she asked to write a thank-you note because she had such a great time at her dental visit! Thank you.

Kate

Professional and friendly

I had a really bad experience with a prior dentist and didn’t want to go back to another dentist for fear of what the prior dentist did to my teeth. I have to say I LOVE this dentist and all the staff here. My fear is gone and I enjoy going to the dentist now. I highly recommend this office!
