Alpha Delta Gamma
Alpha Delta Gamma (ADG) is a Catholic Greek-letter fraternity in the National Interfraternity Conference (NIC). It was founded on October 10, 1924, at Loyola University Chicago by four students who wanted a brotherhood based on Christian ideals, true manhood, sound learning, and unity.
The fraternity grew slowly and conservatively, chartering a total of 32 chapters in its history. Today, nine chapters are active at private and public colleges across the United States, from Los Angeles to Atlanta. Most chapters are at Catholic universities, but there are no religious requirements for membership.
ADG began as the National Catholic-College Fraternity, then became the National Catholic Social Fraternity as it expanded beyond Catholic schools. The Beta chapter was created on October 26, 1927, when Delta Theta from Saint Louis University affiliated with the Loyola Chicago chapter.
