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.

Withheld Needed Medication
This dr has been covering for my primary care dr while my dr is on vacation. When I requested a refill of medications, he approved the 2 medications right away. For the 3rd med, waited 3 days, then required a urine test but didn't notify me. When I found out, I did the test right away. Now, he won't release the med until he gets the urine results. In my many years of taking this med, I have no history of incorrect use. This man has never met me, yet he's withholding medication.
