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.

The patient portal is really bad, no real valuable details are shown. I wasted money and time doing a heart monitor and sending it in when I found out I have a heart condition. The staff never got back to me or sent nothing about the results from the monitor. No one reached out to me and the doctor refused to share information with me when I moved and could no longer go to this provider in-person.
