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.

They’ve made us wait for the last time! Took over a month to get 3 you’d annual checkup and then on a Saturday where there is only one other car in the parking lot we have to wait 1 hour to be seen on an 80 degree sunny day. Have stupid question are to fill it prior when we already completed whatever they sent us via email through portal and their examinations nowhere near as thorough as what we received at prior physician in a northern state. Very done with this group and you can do better!
