On December 2, 1920, Alpha Kappa Alpha Sorority,Inc., Gamma Omega, the third oldest graduate chapter in the organization, was first chartered under the name Mu Graduate Chapter in St. Louis, Missouri. In the late 1910s, AKA college graduates, returning to St. Louis or relocating to the City for employment, found themselves in a city without a chapter. Committed to the goals of AKA and the desire to continue her legacy in the St. Louis community, especially in the area of scholarship for African American females attending the Charles Sumner High School, six women gathered and planned the establishment of a graduate chapter at the home of Helen McWorter. With the guidance of AKA National President Loraine Richardson Green and AKA Central and Western Organizer Pauline Kigh Reed, Mu Graduate Chapter was chartered on December 2, 1920. In 1922, Mu Graduate was renamed Gamma Omega.
For 94 years, Alpha Kappa Alpha Sorority, Inc., Gamma Omega Chapter has transcended time in the St. Louis community, enriching lives through scholarship, community betterment, and sisterhood. The original Chapter goals were to (1) vitalize the ideals of Alpha Kappa Alpha Sorority, (2) foster civic and educational movements, and (3) encourage young women to attain a college education. The Chapter has maintained these timeless goals with adaptability, resourcefulness, and updated objectives to improve and expand programs to enhance and augment service to the Community and “Service to All Mankind”.
