• Love, Honor and Truth!

    The Epsilon Epsilon Chapter at Oklahoma State University was founded in 1920. In 1929, the Epsilon Epsilon Chapter built the 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 but one that lasts a lifetime. Throughout history the brotherhood has maintained close relationships, among alumni and active brothers, that demonstrates a commitment to Sigma Nu fraternity at OSU as well as nationally. 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.
