But, looking at the Pi Beta Phi website from Stanford, where she attended undergraduate, it says:
"Cal Alpha was the first Pi Beta Phi Chapter established in California. It was originally chartered in 1893, two years after Stanford University was founded. However, in 1897, anti-fraternity legislation forced the chapter to withdraw. It was re-established in 1905 and the Pi Phis inhabited what is now the French House until 1944 when Stanford imposed the infamous ban on all women's fraternities.
In December of 1977, the Board of Trustees voted through Title IX to lift the anti-fraternity ban. By April of 1978, a group of fifteen pledges participated in Stanford's first Rush since 1944. California Alpha was officially rechartered during a long weekend of initiation, banquet, and reception."
So, I guess she's not! Unless she's an alum initiate.
