Sigma Nu Anniversaries

Honoring Our Legacy Through the Years

For over a century, the Gamma Kappa Chapter of Sigma Nu at the University of Colorado has built a tradition of excellence, brotherhood, and honor. Each anniversary represents not just a milestone in time, but a celebration of the values and individuals that have shaped our chapter’s enduring legacy.

From the dedication of our bronze buffalo “Sluggo” at the 120th Anniversary to honoring icons like astronaut Vance Devoe Brand and CU basketball legend Burdie Haldorson, these gatherings unite alumni, active brothers, and future leaders to reflect on our history and look ahead to our future.

Below, explore highlights from each major anniversary, including historic dedications, memorials, and the remarkable brothers we’ve honored over the years.
