Sigma Nu’s Epsilon Mu chapter joined the Butler community in 1926. Chapter members volunteer in the community at organizations such as the U.S. Dream Academy, Special Olympics, and Gleaner’s Food Bank. Sigma Nu’s annual Snuperbowl—a powder-puff football tournament among Butler sororities in the spring—benefits Habitat for Humanity. Around Halloween, the gentlemen put on Voodoo Week, which is dedicated to raising money for the U.S. Dream Academy, and they also hold an annual Dodgeball Tournament in the fall.
