The Epsilon Epsilon Chapter at Oklahoma State University was founded in 1920. In 1929, the Epsilon Epsilon Chapter built a chapter house, where the active brotherhood still resides to this day. Since 1920 Sigma Nu has established a reputation of initiating OSU’s strongest undergraduate men. Becoming a Sigma Nu at Oklahoma State has proven to be more than just a 4 year college experience. Throughout history our brotherhood has maintained close relationships, among alumni and active brothers, that demonstrates commitment to Sigma Nu fraternity at OSU and on a national scale. It is no question that our Alumni involvement remains one of the strongest on campus as well. This is evident by our recent $2.1 million house renovation completed in 2004 made possible by their support.
