I was in a sorority at Pepperdine...what do you want to know?
There are seven sororities, all excellent groups (the founding members of NPC) - Alpha Phi, Delta Delta Delta, Delta Gamma, Gamma Phi Beta, Kappa Alpha Theta, Kappa Kappa Gamma, Pi Beta Phi. Rush is in the fall, toward the end of September, and about 30% of the women on campus are greek. Recruitment is "no frills." It is much more casual than what you would find in the south or at USC, but due to the number of chapters, it still has a competitive feel to it. Since the school is filled with overachievers, it sometimes results in lots of pouting during rush from women who are used to getting everything they want but don't get into their first choice sorority. Members of the sororities are supportive of each other, and each of the chapters is diverse in terms of race, home town/state and majors.
There are no houses, so costs are limited to dues and new member fees. Panhellenic will give you a list of fees for each chapter during recruitment.
Recommendations are not mandatory at Pepperdine, but I never view recs as a bad thing. If you get some, you will make yourself stand out.
Feel free to post or PM me if you have any other questions
Excited to see someone interested in Pepp recruitment!
