Are the people at the hospital he is at aware that he has WG? They need to get him started on WG meds even if he is going to be moved. Thinking about the CC or Mayo is a good plan in the long run, but he is not going to get in there immediately and he needs immediate treatment for WG along with all the other stuff he is dealing with. So I hope you can get at least get him moved over to the recommended hospital; there isn't time to look into CC and Mayo right now, it seems to me. Someone else can give you an idea of the costs at those places, I imagine.
