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.
