Trinity has many offerings in the theatre department. A highlight of the year, the Upper School Spring Musical is an annual favorite, performing to a capacity-filled Willett Hall on all three nightly performances. Each year, over 100 students participate in Trinity School’s production of a musical. Trinity’s annual musical is a unique opportunity for students. Any 10th-12th grader can be in the play and it is completely student-run—from the set design, lights, sound, props, makeup, and choreography. It is a culmination of their work done during classes taken at Trinity.
