About Us

Sigma Nu Delta Rho is the oldest Fraternity at Colorado State University, receiving our charter in August of 1915. One hundred years has taught us how to develop our men into the best they can be. We are a values based organization focused on Love, Honor, and Truth.

Our History

Sigma Nu was founded nationally in 1869, when three brave men chose to stand up against hazing at Virginia Military Institute. Sigma Nu carries this tradition on today, we are and always will be an ANTI-HAZING organization. We believe that hazing degrades a brotherhood and we instead ask our new members to prove themselves through campus leadership, scholarship, and honor.

Our Vision

Sigma Nu’s executive board is dedicated to building the chapter into the best at CSU. Our visionary leaders challenge the chapter to grow and make meaningful changes in the lives of our brothers and in our community. Keeping that in mind, brothers in Sigma Nu remember to have fun along the way. Our ultimate goal is our brothers leave CSU knowing that Sigma Nu was the best decision they ever made.
