We offer leadership positions that let you learn and grow while being supported by your siblings and alumni. Penn ADPhi Society is the newly formed Penn chapter of the national co-ed fraternity established in 1832 (and separated from the Alpha Delta Phi fraternity in 1992). It is the only nationally recognized co-ed fraternity on the Penn campus which offers a strong alumni network and tight bonds
with other undergraduate chapters (such as those at Brown, Wesleyan, Stanford, Binghamton, and the University of New Hampshire).
