Founded in 1865, the Alpha Tau Omega fraternity has become one of the most extensive Greek Life organizations in the nation. Founded three days before COVID hit Boulder in 2019, the Nexus Chapter of ATΩ in Boulder is one of the fastest-growing fraternities on campus. As the National Leadership Fraternity, ATΩ is constantly striving to develop college men into the premier frontrunners both CU and the United States need. Every brother consistently lives the Creed, but specifically the line, “To know no North, no South, no East, no West, but to know man as man”. Every member of the Fraternity can recite it, and it establishes a standard for what ATΩ‘s honor is, including the uniqueness and value of every Brother. Embracing each other’s differences has allowed us to bind like no other on campus. Every semester, we conduct philanthropy events, donating to organizations like Sister Carmen, a local food bank, and charity. Last semester, we held a flag football intermural team and we expect this to be a tradition for semesters to come. During this next semester, our chapter hopes to officially charter and become recognized in the nationwide brotherhood of Alpha Tau Omega.

Phi Gamma Delta (FIJI)
Beta Kappa Chapter
Phi Gamma Delta, commonly known as FIJI or Phi Gam, is a social fraternity with more than 158 active chapters and 13 colonies across the United States and Canada. It was founded at Jefferson College, Pennsylvania, in 1848. Our beliefs: Phi Gamma Delta has chosen not to use the term alumni for members who have graduated; post-collegiate members are referred to as Graduate Brothers, to imply that membership extends past the undergraduate experience. Similarly, one of the mottoes used by the organization is, "Not For College Days Alone".Phi Gamma Delta's mission statement lists five core values for its members: friendship, knowledge, service, morality, and excellence. In addition, members are encouraged to live by three priorities in a specific order: first, scholarship, second, fraternity, and third, self. This ordering is because members attend university with the foremost goal of receiving an education and that Phi Gamma Delta is a fraternity that promotes scholastic achievement amongst its members.
