Dr. Stevens is a fantastic surgeon. He has performed over 400 spinal surgeries and came highly recommended by volunteers and staff at Scottsdale Healthcare - Dr. Stevens corrected my 62 degree scoliosis curve. The surgery was further complicated by the fact that I had severe osteoporosis in my lumbar spine. If Dr. Stevens was not as experienced and knowledgeable as he is, my surgery would not have succeeded. Don't let his confident manner scare you away. He is the best!
