Phi Beta isn't a service fraternity in the sense that you are posting about JayBee. Our official name is
Phi Beta Fraternity: National Professional Association for the Creative and Performing Arts, so as you can see, we're a professional group. (And belong to
PFA).
We
are affected by Title IX, though. In fact, I just recently came across an old magazine article that mentioned the fraternity's vote on which way to go with Title IX (open membership to men or change our premise). I am proud that we now allow men, because I know some great brothers that I wouldn't have otherwise!
