Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

I only met with Dr. Kanagarajan once but he seemed very knowledgeable and confident. The office staff however, is awful! Just in the past 3 months, I have been wrongly informed of my medical diagnosis, showed up at the office to pick up my prescription because no one would return my calls and then they called in the wrong medication for me. Dr. K wanted me to stop medication but no one called to tell me, the NP said she would call me the next day.. that was a week ago and I've called 3x since.
