Founded in 2005, Theatre Horizon is an organization presenting plays and musicals in Norristown, PA. In addition to performances at its 120-seat venue, Theatre Horizon offers classes and camps for children, as well as a drama program for individuals on the autism spectrum. The company received American Theatre Wing's National Theatre Company Award in 2017, one of only twelve companies in the nation to be honored with this award from the organization that presents the Tony Awards. In recent years, it has presented the world premiere of Pew Fellow James Ijames’ White and regional premieres of The Color Purple: An American Musical and The Few by Samuel D. Hunter. In 2020, Theatre Horizon received a Center Project grant for Our Norristown, a large-scale play with music that draws on the varied stories of Norristown’s residents as it challenges the myth of American small-town homogeneity.
