St. Thomas's only full-fledged semi-professional theater has been presenting full-length plays and musicals since 1991. Since 2000 it has been located in an air-conditioned 140-seat facility (which used to be a print shop) on the grounds of the Tillett Gardens arts center. Past seasons have seen productions of Hair, Rent, One Flew Over the Cuckoo's Nest, and The Importance of Being Earnest. There are also semester-long workshops for children and teens, and a film series.
