One more thing to add: As my username implies, I am in D.C. -- but I can travel anywhere on the East Coast if there are doctors people recommend. I have an appointment with Dr. Moskovitz @ GW next week, and one in August with Dr. Horowitz at Mass General. I've tried to make an appointment with Dr. Schwartzman in Philly, but I've been told he's booked until 2015 -- and that others in his office also have very long waits.
