Shi-Feng has treated me a number of times over the last few years. I was suffering from really bad chronic neck pain. At first I resisted physical therapy and went straight for a series of shots which did not work. After working with Shi-Feng for several months, and with following his exercise regime at home, my pain went away. It is now two years later and I have no pain in my neck, and I occasionally do the exercises Shi-Feng recommended. I am very grateful to Shi-Feng for helping me get better. He’s the best!
