Established in 1902, Sigma Nu is the oldest fraternity at the University of Colorado. The chapter has initiated over 2,000 members, including bandleader Glenn Miller, astronaut Vance Brand, and many other influential men. Our historic property is one of the largest fraternity compounds in the country, occupying an entire block only a five-minute walk from campus. We invite you to explore our website to learn more about our housing, enrichment programs and long tradition of “excelling with honor”. To be a Sigma Nu is to become something more and to make friends who become brothers for life.
