Sorry--I also responded on the listserv, but will also post this here in case others are interested. Hoagies has a list
http://www.hoagiesgifted.org/psychologists.htm#ufl
which in my very brief experience largely overlaps with the recommendations from the Davidson people. It's good you're going to a specialist, though--we had all kinds of trouble stemming from an uninformed evaluation last year and will be working through it for years to come.
Best of luck!
