Alpha Psi Omega is the national theatre honor fraternity. The William & Mary chapter is called the Alpha Delta Nu Cast - we take new members every Spring who exhibit exemplary skill and passion for the performing arts. Members work with the Department of Theatre, Speech, and Dance in collaboration with the Theatre Student Association (TSA) to help our performance community thrive.

The purpose of this, the Alpha Delta Nu chapter of Alpha Psi Omega is to stimulate interest in theatre activities at the College of William & Mary and to secure for the college all the advantages provided by a large national honor society. By electing students to membership, the society provides a reward for their participation in theatre activities of The College. The chapter is not intended to take the place of any existing theatre organization.
