Rush University Medical Center in Chicago has announced a $20 million gift from John M. Boler and his wife, Mary Jo, to create imaging centers to better diagnose and treat patients for everything from heart attacks to cancers.

The new facility, which will be named the Mary Jo and John Boler Centers for Advanced Imaging in honor of the couple's gift, will be located in new hospital and ambulatory care units that will be built in the coming years as part of the center's redevelopment plan. The gift also will establish an endowment fund in the Bolers' name to ensure that Rush is able to take full advantage of the rapid evolution of the science and technology of imaging.

"We are deeply appreciative of the Boler family's generosity and commitment to Rush University Medical Center," said Rush president and CEO Larry J. Goodman. "This is a landmark contribution that substantially helps us fulfill our ambitious plans for transformation of the Rush campus. The Boler family will forever be remembered for their generosity and how they helped Rush improve care by making available the best possible imaging for our patients."

John Boler is chairman of the Itasca-based Boler Company, one of the largest privately held firms in the trucking industry.
