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.

×Post a ResponseAre you Dr. Feng?
Dr. Feng himself is a decent GI doc but everything that goes along with becoming a patient at his office is not. They billed my insurance company $4,000 for a simple colonoscopy in which I was at the facility for less than two hours. The issue is that they perform their procedures at an out patient hospital facility, so you are charged as if you've been admitted into the hospital. Secondly, his medical assistant has a major attitude when you ask her any questions and she would turn anything you say into a full blown debate. She often takes 2-3 days to return phone calls. It is simply not worth the financial strain and emotional exhaustion to continue to be a patient of his.
