Dr. Simpson is the best. Very smart, very caring, nice.
Dr. Simpson is always attentive and willing to spend as much time as you need with her. Always confident that she will competently take care of my dermatological needs. Very kind and informative.
Feel like my skin check doesn't compare to my previous dermatologist. Not sure if it's the dr. or because I'm on Medicare. Definitely not as thorough!!!
#10. As a rule do not recommend. Also too many places etc. -
