Gamma Sigma Sigma National Service Sorority was founded by six organizations: Alpha Gamma Chi, Booster Squad of Brooklyn College, Gamma Sigma Sigma, Omega Service Sorority, Phi Gamma and the Women’s Service Organization.In October 1952, representatives met for the Constitutional Convention at Beekman Towers in New York City.
During the weekend, the group decided on a name, colors, and the first charters were given to the schools in attendance. October 12, 1952 is recognized as the national Founder's Day of Gamma Sigma Sigma National Service Sorority.
While many sororities and fraternities attribute their founding notable individuals, Gamma Sigma Sigma recognizes its founding schools. Margaret Zimmerman, second National President said, “We recognized that it took many people....” All those in attendance on the final day of the Constitutional Convention are recognized as the founding schools.
