Program Information Theatre Experience of Southern California has been providing exemplary extracurricular musical theatre opportunities for the youth of your community since 1993. Our program offers participants the unique opportunity to become part of the cast of a large musical theatre production on a non-threatening, non-competitive basis.All children who register become part of our cast and receive training in voice, dance and acting technique. At the completion of 14 weeks of rehearsal our cast takes part in production week rehearsals and performances. In addition to exposing children to the arts and music, participation in a program such as ours assists students with concentration, comprehension, focusing skills, while building the self-esteem and self-confidence of the child.
