Dennis Millirons, who guided Libertyville, IL-based Condell Medical Center in Libertyville through a challenging period in the hospital's 80-year history, is resigning effective Jan. 13. The news comes weeks after the hospital paid a huge healthcare fraud settlement and was purchased by Advocate Health Care. The problematic deals with physicians were largely negotiated before Millirons arrived at Condell and during a period of financial unrest for the hospital.
