The men of the Nu Associate Chapter of Sigma Chi at Northwestern University would like to thank you for visiting our website. Sigma Chi Nu is the present name for what was formerly the Sigma Chi Omega Chapter. The Omega Chapter was founded in 1869 at Northwestern and has been involved in campus leadership, academic excellence, and community service for over 150 years. During that time, over 2,500 Northwestern students have expanded their college experience through their membership in Sigma Chi. Sigs are involved in every aspect of campus life, from business fraternities to theatre, and from sports to religious groups. Our Chapter believes in the Spirit of Sigma Chi, which states that “different temperaments, talents, and convictions” are key to any organization’s success. We invite you to explore our website and see if Sigma Chi could be a good fit for you.
