Join us for classes after school

Our classes are over for the 22-23 school year. Look for registration for fall classes soon.  We will start the week of September 11, 2023.

Grandstreet Theatre School helps develop young actors between the ages of 5 and 18. Students attend classes once a week during the school year with others in the same age group.

Grandstreet’s Theatre School expands student skills in character development, improvisation and playmaking while providing practical experience in rehearsal techniques. Class work is aimed at building character – both on and off the stage.

The Theatre School’s goal is to provide training that inspires creative thinking, self-confidence, effective communication skills, fluid movement and vocal control. Each student receives training in acting, voice and diction, singing, movement, dance improvisation, musical theatre and directing.

Attending Grandstreet’s Theatre School Session 1 qualifies the student to audition for the popular Christmas show running in December.

Make sure you join our BAND
