Patient Reviews
Jun 01, 2023
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.
