Arteriovenous Malformation (AVM) in brain

Does anyone know which Mayo Clinic location has experience with Arteriovenous Malformation (AVM) in brain? My wife has had a balance problem for the last few weeks. Her primary doctor had her complete 2 MRAs and a MRI. Her primary physician says she has symptomatic AVM. The earliest we can get a neurologist, here in Maryland, to look at my wife is 2 1/2 weeks. I would like to see if we could get an earlier appointment with one of the Mayo Clinics that deals with AVM.
