Delta Phi Epsilon just chartered the Zeta Epsilon chapter at Carleton University in Ottawa, Ontario this evening!!!

CSU Dominguez Hills:
Phi Sigma Sigma closed their chapter in fall 2015

Oh, hate hearing this. CSU-DH now has no sororities.

Their website says they have NPHC and MGC sororities...even if they don't have PHC sororities anymore.

Been looking through our magazine archives and I have some updates on closing and opening dates, and even a whole chapter not listed! I will likely have more by next week to report on.

Gamma Zeta- Texas Christian University: relinquished charter to nationals, effective December 1993 to correct it from the currently listed 1992

Omega Xi- University of Cincinnati: was actually dormant from November 1988 to January 1991; installation was Jan 18-20, 1991

Zeta Eta- Loyola Marymount University: currently not listed; was installed April 27, 1991; closed fall 1997 due to low numbers

Beta Gamma- Monmouth College: relinquished charter, effective after Spring Semester 1996 due to low numbers
