I was referred to AZ Bone and Joint by my physician at Life Care of Paradise Valley because of bone on bone arthritis in both knees and severe pain which limited my ability to walk.. I was seen by Dr. Martin for diagnosis and PA Ryan Marinone for Cortisone injections. It was difficult getting my wheelchair into the treatment area and I was totally impressed by the extra assistance provided by Dr. Martin, PA Marinone and staff. Their help allowed me to get into the treatment area from the waiting room while respecting my dignity and privacy. I just got the injections yesterday and hope they will be successful. If I could recommend Dr. Martin and PA Marinone any higher I would!
