The way Iowa Mennonite School will use $50,000 in contest winnings will be revealed tomorrow. Last fall IMS won the money through U.S. Cellular’s Calling All Communities contest, and at an open house the school is holding, a discussion will be held on where that money will go. Director of Enrollment Candi Schmieder says the event titled Celebrate IMS! will also include a tour of the campus and classrooms. The open house runs from noon to 3pm and includes a free lunch.
