I chose to go to Klimas - I am looking forward very much to seeing Dr. Klimas and think I made the right decision for me...so we'll see how it goes.
Good luck, dsdmom! I hope she's able to help you! You'll have to let us know how it goes.
I too had cybercat's experience when I called Peterson's office (the receptionist was really nice in my case!) He has a 900 patient waiting list, and as mentioned, sees the patients he wishes to first. A Peterson patient mentioned that he might be involved in the WPI clinic in the future. That's another option too, when they open. Right now I'm (slowly) working on getting some preliminary bloodwork done and hoping it will make me more attractive as a Peterson patient. However that's just a guess. I have no idea what his criteria might be.
Like Cort said, though, seeing these doctors is a stab in the dark. But every few years it's worth it to try something, for me.
