Western Michigan University School of Medicine is a collaboration of Western Michigan University and Kalamazoo's two teaching hospitals, Borgess Health and Bronson Healthcare. It has been in planning since 2008 and was granted preliminary accreditation from the Liaison Committee on Medical Education in 2012. Welcoming its first class in fall 2014, the school is a private 501(c)(3) nonprofit corporation supported by private gifts, clinical revenue, research activity, tuition from students, and endowment income. In March 2011, Western Michigan University received a gift of $100 million for the medical school from anonymous donors. The home of the new medical school includes the WMU School of Medicine Clinics, a modern 60,000 square foot clinical building on the Oakland Drive Campus, and a seven-story 350,000 square foot educational building in downtown Kalamazoo that was donated by MPI Research. Located on the new W.E. Upjohn Campus, the educational building is undergoing a $68 million renovation and expansion project that opens in June 2014.
