It is located at a theatre complex called the Mead Center for American Theater since its opening in 2010 after extensive renovation; this included construction of a third small theater in a complex with two stages: one a theatre in the round and the other a proscenium style. The Artistic Director is Molly Smith and the Executive Producer is Edgar Dobie. It is the largest company in the country dedicated to American plays and playwrights.
It commissions and develops new plays through the American Voices New Play Institute. Established in 1950, the company now serves an annual audience of more than 300,000.
Its productions have received numerous local and national awards, including the Tony Award for best regional theater.
