The memories created at Sigma Nu Boulder last a lifetime. They are among the best years of our lives, made so by brothers who become lifelong friends. With more than 2,000 alums, Sigma Nu has one of the largest fraternity alumni groups at CU Boulder.
We invite all alums to explore this section and learn about ways you can get involved with the chapter:
- Come back and visit your old room!
- Become an Alumni Big Brother mentor to a GK upper classman
- Speak to the chapter at a leadership session
- Join our LinkedIn Group to find brothers you’ve lost touch with, connect with new ones, or post a job or internship that will help prepare a Sigma Nu brother for the job market
- Join with your classmates to honor a brother who has passed on with a remembrance plaque on the new Buffalo Brothers Memorial in front of the main house (our new bronze buffalo, “Sluggo”)
