Rockland County's Oldest Non-Profit Theatre, @antrim.playhouse AntrimPlayhouse.com The Antrim Playhouse has been a staple of Rockland County and the surrounding communities for over 100 years. As a non-profit organization, our mission has always been to bring people together through the power of theatre. Each year we produce a season of full-scale productions of both plays and musicals, as well as smaller-scale productions that focus on the works of local artists. Antrim is committed to telling stories that reflect our diverse community, as well as being a place that provides a creative outlet - not just for performers - but for designers and those who wish to be involved in any aspect of theatre.
