The Zeta Pi Chapter of Alpha Phi began in late 1980 when a colony of Alpha Phi was set up at CWRU. Working diligently to become an official chapter, the executive board set up goals for the chapter and for rush. After fall rush in 1981, Alpha Phi gained new pledges and pushed the numbers to nearly forty. The new sisters of Alpha Phi worked together with Alpha Phi International and CWRU to eventually make Alpha Phi an official chapter in March of 1982. Alpha Phi is the oldest national sorority at Case Western Reserve University.
