There's the Center for Complex Diseases in Mountain View, California, with Dr. Kaufman and Dr. Bela Chheda. I don't know what sort of a wait there is - I think less of a wait for Dr. Chheda. I do know it's very expensive.
Since you don't have insurance, I am assuming you will have to pay cash wherever you go, so does that mean you're looking for a cheaper doctor? Or just that insurance is not an issue?
