Hi and welcome to the Chiari forum.
I am not familiar with the UPMC, but there is a chiari dr in Pittsburgh a Dr Bejjanni.....I believe his info is on our list of drs and I suggest u do some research as I did not have first hand experience with him.

Many chiari drs have long waiting times, and I know it may be difficult, but do not go to a dr just bcuz they may get u in sooner...the one with the wait may be more experienced and the better option...ask to be placed on the cancellation list...
May I ask what symptoms u r dealing with?
