Leaders in Prince George's County, MD, have chosen a lawyer and two financial gurus to represent the county on an authority designed to seek new owners for the county's hospital system. The group will be joined by three members selected by Gov. Martin O'Malley and a member chosen jointly by the Senate president and speaker of the House of Delegates. The hospital system is owned by the county and managed by the nonprofit Dimensions Healthcare. The authority will solicit bids from healthcare companies interested in taking over the struggling system.
