Neil J. Moore is the new president and chief executive of Dimensions Healthcare System in Prince George's County. Moore, who appointment was announced Thursday after a unanimous vote by Dimensions' board, stepped in last month as acting chief to replace Kenneth Glover. Glover resigned after he became the focus of an internal investigation into alleged kickbacks while Jack B. Johnson (D) was county executive. Glover left the healthcare company as federal officials investigated Johnson's dealings and spinoff cases. As he took charge after Glover's departure, Moore dismissed Glover's public relations chief, Louise Ross, and his chief of staff, Linda Currie. Moore has been Dimensions' CFO for nearly seven years. From 1989 to 2005, he served in senior leadership positions in healthcare organizations in New York City.
