"I came to the office with constant pain in my upper back. After about one month of treatment with Dr. John, I was pain free! The changes I did not expect to occur were noted by my son and husband. They felt my posture was better and there seemed to be less of a hump in my upper back area. After almost two years of treatment, I am still walking erect. So many people warned me about becoming crippled with a bad adjustment. I have complete faith in Dr. John."
