Sigma Pi Fraternity at Colorado State University

Sigma Pi Fraternity at Colorado State University This is the page of Eta-Sigma chapter of Sigma Pi at CSU. We are a fraternal organization of friends called brothers.

Sigma Pi Fraternity was founded in 1897 and stands as one of the strongest and most respected organizations in the Greek letter world with over 135 chapters & colonies; standing as a top ten organization in size, leading college campuses all across North America. Sigma Pi is also the only social Greek-letter organization in North America with a service project designed to give back to our host ins

titutions through our ACE Project (Altruistic Campus Experience). While getting a college degree is their first priority, they balance academics with a variety of activities such as intramural sports, camping, skiing, and other social gatherings. They also raise money for charity and participate in events with other clubs and Greek organizations. There are many benefits and opportunities that Sigma Pi brothers enjoy by becoming part of a larger community including leadership, academic assistance, community service, and others.
