Sigma Delta Tau has connected 65,000 women since 1917. The National Headquarters, located in Carmel, Indiana (just north of Indianapolis), is home to the sorority’s central business office, the SDT Foundation and the national archives. Meetings and workshops are held throughout the year for collegiate and alumnae leaders.
Visiting the National Headquarters is a special experience for sisters. The unique mix of historical archives and contemporary artwork donated by our talented members, adds to the beautiful decor. Inscribed bricks line the Sisterhood Garden pathway right next to the yellow rose bushes and the national founders’ commemorative wall.
