Sigma Pi was founded in 1897 at Vincennes University. Through the Sigma Pi ACE project (Altruistic Campus Experience), Sigma Pi aims to stay close to those initial values through extensive philanthropy. Along those lines, Sigma Pi hosts an annual Easter Egg Hunt for low-income youth and blood drives on-location at the house, among other projects.
The Alpha Phi chapter at UGA began in 1948 as one of 113 national chapters of 90,000 total initiates. Sigma Pi maintains a strong scholarly tradition with brothers represented in Golden Key ODK, Phi Kappa Phi and Delta Epsilon Iota.
