You may want to consider Dr Carol Koski at U of M medical center In Baltimore. She is on the GBS/CIDP advisory board. I went to her many years ago for a second opinion to confirm my dx. I liked her and she seemed to be on top of things.
I see Dr William Stuart at the MS Center of Atlanta. He stays up with all of the new treatment protocals and is not affraid to try different things. An example is, he is now trying me on Tysabri, an MS drug, to see if it will produce similar positive results as are being seen in MS patients.
Good luck in your search.
