Aleph Gimel Chapter

The Acacia International Fraternity was founded in 1904 as a Masonic fraternity, and still hold strong ties to Free Masonry. We first chartered on CU campus over 100 years ago in 1911, making us one of the oldest fraternities at CU. Academics are always put as the first priority as an Acacian. We are active on campus in intramurals such as flag football, basketball, and softball. We embody our motto, "Human Service", by actively participating in numerous philanthropy and service projects within the Boulder community, including Hill cleanups, homeless outreach, and our own Acacia Clause toy drive every Fall. Our house is the most recently built and largest Fraternity house on campus, located at 1715 Aurora Avenue. Brotherhood is a huge part of our lives, and it is what makes us so successful in the classroom and in life. We are seeking well rounded, successful men to take strong leadership positions and to be active on campus and within the Greek community.

It was founded at Jefferson College, Pennsylvania, in 1848. Our beleifs: 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.
