Our founders join together to establish a sorority that prioritized the lifetime experience as a woman of similar ideals, building lasting friendship, and fostering personal growth. Our AU chapter, Gamma Delta, was founded in 1978. Today there are SDT chapters nationwide focused on each sister reaching her fullest potential through intellectual, leadership, and social opportunities.

Sigma Delta Tau has various social and sisterhood events each semester, creating a strong bond within our chapter. Sisters are provided with many leadership opportunities, positions available on our choppers executive in general board, as well as opportunities within our national organization.



Both our national office and our local organizations are deeply involved in philanthropy. Nationally, SDT is partnered with three unique philanthropies; Prevent Child Abuse America, JWI, and Sigma Delta Tau Foundation. In addition to our national philanthropy, we have local philanthropic partnerships. Each philanthropy we support ties in with our overall goal of empowering women of all ages.
