Popcorn Hat Players (PHP) Children’s Theatre has been entertaining children and their families since 1993, bringing fairy tales, folk tales and fables to new audiences every year. Using creative comedy and improvisation, the Players write original adaptations and breathe new life into unforgettable stories.

Harrisburg Shakespeare Company (HSC) has been providing a unique and widely praised cultural resource to the Central PA community since 1994. HSC produces shows at Gamut Theatre's Select Medical Mainstage and tours a Shakespeare work annually to high schools, middle schools and colleges, in addition to the annual Free Shakespeare in the Park.

T.M.I. is Gamut Theatre Group’s in-house improv comedy troupe, and is peopled by some of the most decent, charming and sweet-smelling folk you’d ever want to meet.

Stage Door Series complements and builds upon Gamut’s Mainstage season, through the presentation of engaging and educational workshop productions that highlight the essential elements of theatre: the text, the story, and the action.
