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.

Just FYI, I have been a nurse for ten years so I have a pretty good understanding of how things run and how professional doctors should be. I have been to see him three times and have waited longer than an hour each time. Staff is nice but the doctor orders excessive amount of labs (probably so he can bill your insurance company) and does not explain results or rationalization of any of the lab work done. Would not recommend this physician to any of my family or friends.
