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. Zhang?
Dr. Zhang listens to her patient very well, spends time in explaining medical problems in a very easy to understand manner, and make professional decisions. She is very amiable and accommodates to patients's need, unlike some doctors who are arrogant to their patients. I am very impressed by her patience to fill up required paper work with sufficient details.
