I saw Dr. Thomas and he was great - if you're a new patient the first available appointment will be about 4 months out. He took the time to listen to what I wanted and what my concerns were and actually explained his answers/why he would or would not recommend a certain thing.
One of the prescriptions was making my stomach hurt but I just called their number, spoke to a nurse and a new prescription was called into my pharmacy that day. I also called a couple of weeks later with another question and heard back from the phone nurse that day.
I'd recommend Dr. Thomas to anyone looking for a dermatologist!
