I thought Longwood had some really excellent things to offer. The program director was an affable guy and supportive of residents, per their report. The residents we met over dinner the evening prior to interviews all seemed like nice, level-headed folks. They had good things to say about their program, and it seemed that the 4th years were all going to their first choice fellowships. Some were heading off to good jobs as well. At lunch the next day the group was a bit more reserved... maybe they were tired.
It does seem like there is some traveling involved since Mass Mental is closed, but that isn't at all unique to Boston programs. In fact, that goes for many programs in the Northeast -- Yale, Penn, Mt Sinai, NYU, Cornell all are spread out between two facilities, at least. True, you don't need a car for NYC though.
Word is that the Longwood program is the most balanced of Boston's major three programs, in terms of research exposure and psychotherapy didactics.
That's all I know. 🙂
