The Phi Kappa Psi chapter at UT-Austin is quite good, and is celebrating its centennial anniversary! Its where the late Tex Schram was a Phi Psi.

I'm also Jewish, and I joined Phi Psi, at FSU, in part because religion was a non-issue. We are the oldest non-denominational fraternity, and we had Jewish majority chapters as far back as the 1870s.
This chapter has very rich programming, including leadership retreats in Cabo San Lucas, Mexico, where they stay at the Phi Psi Leadership Academy. You can read about this academy at
