Several alternative Greek organizations are currently undergoing Rush Week.

These subject-specific societies cater to those students aiming to combine the friendship and networking opportunities of a sorority or fraternity with a personal interest or hobby.

Phi Simga Pi is an honors co-ed fraternity “that prides itself on fostering fellowship, scholarship and leadership,” as stated on the group’s website.

Incoming members must maintain a minimum 3.0 GPA and have completed at least 12 hours of college credit.

Alpha Phi Omega, a co-ed service fraternity, combines the characteristic brotherhood philosophy with the benefit of giving back to the Norman community.

“APO can offer students who are wary of joining an expensive, sometimes exclusive and often homogenous Greek organization an opportunity to build those lifelong friendships and attain the kind of exciting social life that fraternities and sororities provide,” Pledgemaster Deanna Strafuss said.

“The social aspects are important, but we all recognize that what really unites us is our dedication to helping others,” the College of Arts and Sciences senior said in an e-mail.

Both organizations are holding events through Sept. 12. Phi Sigma Pi’s Bid Party is Sept. 10 and Alpha Phi Omega’s Pledge Pinning Ceremony is Sept. 12.
