Hi and welcome to the Chiari forum.
We do have lists of Drs that I will post here for you....but I want to advise you they are not referrals nor endorsements...the lists are here and were compiled by members of Drs they have been to, and treated by and liked.... you need to use the list as a tool to have a starting place to research Drs...
