Alpha Sigma Tau was the first national Greek organization for women to be established at Belmont University. The sisters of AST focus on academic excellence, leadership, and service. Members of Alpha Sigma Tau strive to be active, self-reliant, and trustworthy women. ASTs can be seen on homecoming court, in SGA, as RA's, starring in musicals, in Fall Follies, in the Honors Program, and well as other campus activities.
