All Gregory School students have opportunities to become involved in theater, and to participate in performances and productions. Starting in Middle School, the arts are integrated into the academic curriculum, and students learn the basics of the creative process and develop performance skills. As they move into the Upper School, those foundational skills are developed, and all students can audition to act, sing, and/or dance in every school production. Additionally, technical theater students design and create sets, costumes, and lighting and produce the shows backstage, including running the lighting and sound systems in the theater. All interested students then work together to produce several main-stage productions each year. Facilities include a 370-seat theater with professional sound and lighting equipment, orchestra pit, green room, lobby, and ticket booth.
