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.

Totally mismanaged my case yesterday, overriding the orders for a procedure minutes before it was to be done in hospital without consultation with doctor. Resulted in a horrible pain from complication that required I return to an ER with admission to undo what he did yesterday. Gave no way to contact and was unresponsive to phone left at number provideon his website info. Every doc I've seen since this ordeal has confirmed my procedure was inappropriate and mismanaged. Dangerous loose cannon.
