finding a practitioner?

Hi, i live in San Francisco, ca., and I am wondering if there are any Dorn method practitioners here. I have had a persistent, stiff, painful neck problem for over a year, and have had several different treatments for it, chiro, trager, acupuncture etc, but no luck. Dorn sounds interesting, and not as jarring as chiro. Can you direct me anywhere here? thanks, deven
