The Omega Epsilon Chapter of Sigma Pi was founded on the Potsdam campus in March 1981. As a national fraternity, the brothers prided themselves on their progress, as exemplified by their motto: "Quality in all that we do, or we don't do it at all."
Sigma Pi participated in community and social events on campus, along with the help of the Sigma Pi Emeralds.
Sigma Pi was most known in the North Country for their work raising money for multiple sclerosis research, with their annual "Bed Push."
Sigma Pi is no longer recognized by the College.
