Pepperdine is not southern-esque and most chapters will consider pledging non-freshmen. Recs are helpful but are by no means necessary. There are 7 groups.
Alpha Phi
Delta Gamma
Delta Delta Delta
Gamma Phi
Kappa Alpha Theta
Kappa Kappa Gamma
Pi Beta Phi
The chapters are not housed and recruitment takes place mid-fall semester in classrooms after classes are over for the evening.
Chris, their Greek Advisor, is a really nice guy and I am sure he'd be happy to guide you toward their new Panhellenic officers to get your questions answered. His email is
Chris.VanVelzer@pepperdine.edu.
Good luck!
