Corbett made the announcement Wednesday, a day after The Associated Press reported that changes were expected among his top staff.
Veteran Republican lobbyist and political strategist Leslie Gromis Baker will replace Steve Aichele as Corbett's chief of staff. Aichele was Corbett's chief counsel when he took office in January 2011, but became chief of staff last year in a separate shake-up.
Corbett's legislative secretary Christopher Carusone is leaving after a year to become a partner in a Philadelphia-based law firm. Andrew Ritter, Carusone's deputy, will serve as his replacement on an acting basis.
