The IMA's conservation department was established in 1970 by the museum's first full-time conservator, Paul Spheeris, and quickly became known as a regional center for conservation. In 1978, the department began providing consulting services to regional institutions, taking on contracts from across the Midwest. An early high-profile contract involved the preservation of 45 governors' portraits over the course of 15 months. The 1979 exhibit, "Portraits and Painters of the Governors of Indiana", was held at the IMA from January to March before the portraits were placed on permanent display at the Indiana Statehouse. Other major regional projects have included the conservation and restoration of the Thomas Hart Benton murals, first created for the Indiana Hall at the 1933 Chicago World's Fair and now located at Indiana University, the Wishard Memorial Hospital murals, the Otto Stark and Clifton Wheeler murals in Indianapolis Public School 54, and most recently the restoration of the May Wright Sewall Memorial Torches at Herron High School, the former site of the John Herron Art Institute.
