Actually, in the sf case, I believe the $600 includes a dr's visit with complete work-up, plus the quantumsource biofeedback for $300. The bio used to be $200, but I think he raised it to $300 recently. So after the 1st visit, it's "ONLY" $300. I noticed others charge alot less; the guy in sf is a md, so you know how they are! Big bucks. However, I'm hoping it will come down as it becomes easier to get. One does not have to be a dr to do it....so maybe a future for me and others there? It seems like a great job. I pledge to do you for free, if I ever get to that place in the future!
