I can't say enough about Dr. Thomas and her staff. I had a problem and was going out of town. They all did everything they could to get me medication before I left town. I got messages and phone calls from the nurses and Dr. Thomas herself. When I returned and scheduled an appointment, it was going to be a week out because she was booked. The next day I got a message stating that Dr. Thomas saw my appointment and she said she would squeeze me in the very next day and she did!Outstanding service!

September 11, 2025
I've been seeing Dr. Thomas for years and I hope that I never have to find another dermatologist. For a person who's enjoyed being and working outdoors, it wasn't fun to hear that I now needed to be covered head to toe outside. She is very compassionate though and made it easier. Her sense of humor is welcome and she's an excellent diagnostician. The only unpleasant part is the freeze spray used on pre-cancerous spots. Beats the alternative.
