Hi and welcome to the Chiari forum.
U can access the list 2 ways, one is on the forum as a thread, it is floating around and I bump it up from time to time and in the Health Pages...Keep in mind the list is of Drs that treated members, not all may be true Chiari specialists and u do have to research them, this is just a starting point for u.

I see u have surgery scheduled....may we ask with whom? and what type of surgery ur Dr is going to do?
Have they ruled out all related conditions?
Keep in mind not all Chiari specialists may be on our list.
