Dr. TOMEY was outstanding. He explained my issue in detail and suggested that I get an MRI to look for any soft tissue injury. he reviewed the x-rays that I had taken to show me the problem. I left feeling very confident about the visit.

Dr has the bedside manner of a rock. When I expressed my anxiety about surgery his response was " then don't get the surgery. It's elective."
