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.

Dr. Marcus is not my doctor, he is my cousin. I turned to him for advice after my heart attack, and that is when I realized how deserving he is of his reputation. His bedside manner is amazing, particularly for someone as revered as he is. He is a very humble man. He is very much like his father, an absolute medical hotshot with zero ego. I wish he were my cardiologist.
