Overland Park-based Sunderland Foundation has donated $2 million to the Kansas University Hospital to support the construction of a new 92-bed facility.

The grant is the largest in the foundation’s more than 60-year history. It will add to the $3.5 million in private funds raised for the building. In February the hospital announced initial gifts from Greg and Deanna Graves and the Burns & McDonnell Foundation.

Sunderland Foundation awards grants to help nonprofits with building projects. The foundation was established by Lester T. Sunderland, one-time president of the Ash Grove Cement Company. Charles Sunderland, current CEO of Ash Grove Cement and great grandson of Lester Sunderland, has been a longtime member of KU Hospital’s board.

The grant will support a proposed facility for neurosciences and oncology at the northeast corner of 39th and Cambridge Street at the hospital’s Kansas City, Kan., campus.

Neuroscience and oncology services at the hospital have grown by 40 percent in five years, the hospital said.
