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.

Visit was short, efficient, dr was pleasant.

Great Medical Advice
During my two visits with Dr. Grenis, he listened to my concerns, gave me options to consider, and was very measured in his response to my condition. He suggested a wait and see approach for my particular issue, as it could possibly resolve itself. He did not push me towards having a surgical procedure if I did not need one immediately. He provided me with very good medical advice.

Top care for my athlete daughter
Daughter fractured finger during basketball game. Urgent care recommended us to see an orthopedic specialist, parents from the club highly recommended POA, POA went above and beyond by getting us an appointment with the best hand specialist in the area. Dr Grenis took the time to examine her and answer all our questions and we had several. Highly recommend POA and Dr Grenis.

Dr. Grenis misdiagnosed me, which is no surprise since he barely looked up from his clipboard in my doctor visit. He was in the room for maybe 4 minutes, barely looked at anything then said it was my wrist joint. It wasn't. He had me do months of physical therapy for no reason, which did not help and only hurt my other wrist which was originally fine. I then found out it was my muscle, not my joint. Dr. Grenis sent me down months of wasted time, money and pain. Very upset with how he handled my issue.
