Please, Please, do your research. Sonoran Spine is a surgery mill designed to get money. Look up the AZ Medical Board. Sonoran Spine was sued for malpractice when people died during surgery. I was told that Spinal Fusion would be successful 70% of the time, in truth it is 40%. Not only that, I was told that Crandall was successful 90% of the time. Since my surgery, I have not been allowed to see Dr. Crandall once. My surgery has failed and I was told by his attendants that I probably need another to fix the first one.
