Hey, saw your post and just wanted to comment. I was diagnosed with a small (3mm) AN in the fall of 2017. Live in Northern NJ but work in the city & met with Sisti at Columbia and had it treated by Gamma Knife in June of 2018. Happy to share my thoughts on doctors and the process I've gone through if you want more info. In short, watch & wait is the way to go, but I had some rapidly deteriorating hearing issues so I gave GK a shot. Anyway, best of luck as you work your way through this. FWIW, I don't think there's any one "correct" approach, it differs on each person's unique situation.
