Long-time Atlanta businessman and developer Tom Bell will serve as interim chairman of the Grady Health Foundation board of directors.

He is temporarily replacing departing chair Peter Andruszkiewicz, former president of Kaiser Permanente of Georgia. Bell is a founding member of Grady Memorial Hospital’s corporate board. He retired as CEO of development firm Cousins Properties Inc. in 2009.

The nonprofit Grady Health Foundation supports the safety net hospital, which cares for many of Atlanta’s poor and uninsured residents.
