MASC is a founding member of the Monroe County Arts Alliance.
Due to the government mandated restrictions on public gatherings, the MASC board of directors has cancelled the remaining events of the 2019-20 season. This includes the season's two remaining shows and the summer camps. The board is still deciding what to do about the MASC membership meeting and the Gala. The board has moved the remaining two shows of this season into the 2020-21 season. The lineup for the 2020-21 season is, in no particular order, Young Frankenstein (musical), Moon Over Buffalo, Bright Star (musical), Watch on the Rhine, and Footlight Frenzy. The dates of these shows has not yet been determined.
Monroe Actors Stage Company is a community theater located in the Historic Capitol Theatre in downtown Waterloo, Illinois. Serving Southern Illinois and the greater St. Louis metro area, MASC produces five shows a year with the purpose of bringing enjoyable and affordable live theatre to the area's residents.
