Sigma Delta Tau
American University
The Gamma Delta chapter of Sigma Delta Tau is a sorority committed to individuality, connection, engagement, and community. Since 1987 we have lived by these guiding values through our philanthropy supporting Prevent Child Abuse America, Jewish Women International, and The Sigma Delta Tau Foundation. You’ll see us on campus celebrating our community and raising awareness for these causes at our spring philanthropy event, Sig Delt Survivor, and our fall philanthropy event, Light the Night. At SDT, we empower each member to reach their fullest potential by building lasting relationships, promoting civic responsibility, and fostering personal growth.
