I'm in Greenville, SC, not too far from you. A local neurologist initially diagnosed my tumor as a meningioma, and referred me to a highly-regarded local neurosurgeon, who diagnosed it as an AN, and although he had some AN experience, he no longer treats them. He insisted I see someone with extensive AN experience -- and warned me against letting any local surgeon operate -- just not enough experience. AN's can be tricky, and this turned out to be the case with mine.
He gave me two referrals, one to Dr. Patel at MUSC in Charleston, another to the head of neurosurgery at Duke -- can't remember his name, but he recommended only their department head. In my case, radiation was not an option due to size (3.0 cm). Yours is smaller. Other semi-local options you may want to consider include Emory, Vanderbilt, and Wake Forest / Bowman Gray Med School.
Others on here have commented that House and maybe Stanford offer free phone consultations if you send them your images.
I would not hesitate to recommend MUSC and Dr. Patel. I received excellent care from them in what turned out to be a very complicated case. However since you may be a candidate for radiation, I would encourage you to seek out other opinions.
The fact that you are having these symptoms, I think indicates it is time to seek out treatment options. Best wishes, and please keep us posted!
