Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

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

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

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

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

This doctor doesn’t not mess around. Dr Marcus tells you straight out. She has become a Doctor that I like to see and talk to. Dr Marcus is a friend. She helped me recover from two strokes. She makes every effort to help you. She’ll hold your hand. She is very very nice. If you’re looking for a doctor that will do what ever it takes. Just listen to her ask questions she’ll tell you what you need to do. She is the nicest doctor I’ve ever met.
