AngelPhiSig,
Phi Sigma Sigma was at LSU! The Omicron Chapter operated from 1927 - 1933. Since it was the only chapter ever chartered in Louisiana, there aren't many alumnae around.
A few years ago, Theta Phi Alpha considered LSU but the start up costs were too great.
I wholeheartedly agree that both organizatiosn have something wonderful to offer!
