Pec Playhouse Theatre (PPT) was formed in 1991 by a group of Pecatonica High School students and recent graduates who wanted to continue performing in theatre after high school. With the help of some supportive adults, PPT was organized and produced its first show, Out of the Frying Pan. This show was funded entirely by membership dues and proceeds from a car wash.
In these early years, shows were performed mostly at Pecatonica High School and occasionally at the American Legion Hall. By 1994, PPT began producing summer musicals starting with The Wizard of Oz. In the summer of 1995, PPT mentored the newly-formed Byron Civic Theatre in presenting its first production, Annie Get Your Gun. PPT was incorporated as a not-for-profit corporation in 1997 and two years later, became a 501(c)(3) tax-exempt organization, making most contributions to the Theatre tax-deductible.
