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.

Its been 6 years since MArch 2011 now but Dr. Sun helped me save my life when I was addicted to crack cocaine. I managed to get clean and stay clean--and though I now have some pretty serious health problems, I' am not smokin'the rent,, as the saying goes. and am doing very well. Because of an unfortunate incident with an very abusive RN at St Francis (the get a lot of Tenderloin patients and it changes them), I go to CPMC or UCSF. But I will always remember JOanna Sun, she is a great healer.
