I know this maybe should go on the student board BUT...

that seems to be mostly high school students, and I'd like some advice from people who have been working in NYC. So, my question is what schools or coaches do working actors go to either between shows or just to keep working on their craft? I'm wondering because I'll just be completing my BFA this winter, and want to keep taking some classes while I audition, but I don't really know anyplace outside of school, and I don't want to end up in a class that's full of retired people and housewives who are bored and looking for something different to do, I want to be with people who are actually working actors. Thanks in advance, and sorry again if maybe this should be on the student board.
