[Sister Havana]

Alpha Phi Omega is coed, although there are a few all-male chapters that were grandfathered in. (Delta at Auburn and Gamma Lambda at Clemson are the two that come to mind). Interestingly, the membership in my chapter was overwhelmingly female when I was there!

There used to be a local coed fraternity at Indiana University called Alpha Theta Tau. I don't know what happened to it.
