The Kappa Sigma Fraternity has a long and distinguished history, both as a national fraternity and as an organization on the Oklahoma State University campus. Kappa Sigma can trace its roots back over 600 years to Bologna, Italy and over 130 years back to its American founding at the University of Virginia in 1869. The Gamma-Psi Chapter of Kappa Sigma at OSU (and formerly Oklahoma A&M) has been a fixture in the Greek community for over 80 years. With continued successful rushes and the strong support of out alumni base of over 1600 men, Kappa Sigma will thrive on the OSU campus for years to come as well. Please take the time to read more of the history of the Kappa Sigma Fraternity and of the Gamma-Psi Chapter at Oklahoma State.
