Yes, saw him. Very thorough in his testing and his looking over your chart (he wants ALL the information prior to the visit). However he seems to have one protocol he uses the most in response to what he finds. It has helped many people. I wasn't able to make use of it at the time due to a symptom/side effect. After that / because of that, he wouldn't work with me. I don't think he goes by the cd57, but believes that the c3a and c4a irregularities as indicative of lyme or mold. I'm glad I went. One thing to look out for: if they tell you that your insurance is accepted, better make sure by calling your insurance company yourself and fully understanding how it works. He does a lot of testing, too. Good luck, e-mail me personally if you want any more information.
