Wonderful, friendly staff!

5 stars Customer since 2005

I have only been to see Dr. Thomas twice, once for an exam/cleaning and once for some repairs to a few fillings. Both times I have been to the office, the staff was very courteous and professional and I was seen right away (no wait time). The hygienists are very professional and friendly. Dr. Thomas did a great job replacing/repairing a few of my old fillings and I was able to get the work done on my lunch hour and be back at work in an hour. I would highly recommend Dr. Thomas and his staff.

I feel really comfortable at Thomas Dentistry. They do an excellent job with cleanings and I especially appreciate that the dentists do not try to "upsale" their patients on additional services. I was actually complimented on my oral hygiene!

5 stars Customer since 2009

I never have a bad experience. I drive over a hundred miles to have my teeth cleaned, because I have never found a better dental office/staff. They are very personable and make me feel like family. I recommend this office whole-heartedly!

Thank you, Dr. Thomas and Nessi! I am so thankful that I was able to get an appointment the same day that I called. You took care of my tooth issue and I know that it cut into your lunch time. Your office is the best!

Exceptional. Haven't had a pain free dental experience in quite a long time. Thanks a million.

Really nice staff (always) - no issues with billing and appointment times that match my schedule. Dr. Thomas is spectacular! What else could you ask for?

Great staff. However, I did not see either of the two dentists who are featured on the website. No one explained this to me when I made the appointment nor when I was in the office. I feel that many dentists' office do this but I find it unacceptable. This does not happen with other types of medical practitioners without being explicitly stated.

As always I was very happy with my visit. Everyone is friendly and polite and I was in and out of there in no time. I have had a fear of dentist in the past and this office has been able to reduce those fears. I know the care I receive will be painless and top quality. Thank you for providing such great service.
