Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

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!
