Thorough jobHelpful advice
September 14, 2025
I truly appreciated Dr Thomas' willingness to handle all of my issues in one visit instead of multiple. This relieves a lot of stress and is much easier to handle. I liked that she listened to me and provided alternatives to what I had been told by other doctors. Dr Thomas will be my permanent Dermatologist. Thank you.

I have been seeing Dr. Thomas for years. She is amazing. Very thorough and caring.
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.

August 8, 2024
Doctor didn't introduce herself to me which I thought was strange. Also when she was finished I wasn't sure what to do, so I dressed and left. Not a lot of personal interaction.

Excellent patient service!
August 7, 2024
While very courteous, I came in for a full body scan and didn't quite receive a full exam. I was told to keep my shorts on during the exam. While being examined on the portions able to be seen, the doctor seemed hesitant to get close and didn't really do an in depth exam. While I didn't have concerns in other places, although I could have missed something I can't see or don't know is an issue. I would have liked a better exam.
August 6, 2024
I'm happy with my care provider only if I can get appointments scheduled with less time to wait would be great

August 1, 2024
I still had to wait about 10-15 minutes before seeing the doctor once I got to the office and then another 5-10 minutes after the nurse left me in the exam room to change. It seemed like a waste of time.
