I am a physician who has a long history of disc herniations leading up to surgery a few years ago. When a new level appeared, I was referred to Jon, and he completely fixed me without surgery. Infact, I went from bent over and barely able to see patients to playing tennis again within 2 weeks, just by doing exercises he prescribed. Now if there is a flare, I revert back to the exercises and it works. I play tennis vigorously and competitively 4-5 times a week. No pain meds, not muscle relaxers!
