Twilk10,
I decided to accept GW's offer, it seemed to be a good fit for me, all things considered (location, resources/opportunity for research and employment following completion of program, possible linkage). I don't know that I have any more information that you wouldn't already have but I did get the feeling like it was a good fit for me and that Dr. Hirshfield and the other faculty take a very personalized approach to each member of the cohort. I know today is the deadline to accept their offer, so feel free to PM me about it going forward if you are coming to DC!
