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.

Best Gastroenterologist in the area.
Dr Mazloum has been my doctor since I was 32 years old. 18 years! Helped save my life when I had a blockage from endometriosis on my colon and other organs.

5 stars....I couldn't be more pleased with Dr Mazloum. I suffered with another Dr for 7 weeks with no results. One week later after seeing Dr. M.....the problem was identified and rectified shortly thereafter. Five stars for him as well as for his bedside manor. Bob R

I had a procedure today with Dr. Mazlaum and am still in shock over how rude and inappropriate he was to me. I was very nervous and instead of offering any comforting words, he literally reprimanded me in front of two surgical nurses and a nurse anesthetist. He threatened to cancel the procedure because of my nervous, joking questions about how the procedure was going to go. He scolded me and I went under anesthesia crying, fearful and feeling battered instead of at ease and reassured.
