      I am shocked to see negative reviews about Dr. Duncan. Dr. Duncan and her staff are nothing but a pleasure to work with. After seeing two other Dermatologists who misdiagnosed me, Dr. Duncan had my issue pegged in a matter of minutes. Not to mention she is nothing but a sweet, caring doctor. If you are on the lookout for a new Dermatologist, she deserves a shot. One thing I should mention is her office is very busy. It can take several weeks get appointment (that's how good she is).

      Dr. Duncan is fantastic. She is personable, thorough, and I am really happy with her dermatologic care. I am also really happy with her staff who are all warm and friendly. I started seeing her a few years ago and I didn't feel the staff she had at that time were friendly or running the office very well. I am so pleased to say that is completely changed for the better!

      Wow she is such a jerk. I honestly would rather break my ACL again then go back.
