September Song Musical Theatre (SSMT) has organized and performed a Broadway musical for the past thirty-eight years. Founded by two educators, Arnie Hayes and Robert "Doc" Kersey, September Song is a non-profit community theatre based in Carroll County Maryland that annually draws a talented cast and production staff from Carroll, Baltimore, Howard, Anne Arundel, and Frederick Counties, as well as Baltimore City and Pennsylvania. We are dedicated to spreading a quality gift of the arts through musical theatre to all of our participants on and off stage as well as to our audiences of all ages.

September Song is a 501(c)3 non-profit organization as a component fund of the Community Foundation of Carroll County.
