Raquel Guillory, a longtime aide to Gov. Martin O’Malley (D), is leaving her job as communications director in the governor’s office for a post at the Department of Business and Economic Development.

Guillory will start next month as an assistant secretary at DBED overseeing marketing and communications. The department is responsible for recruiting new businesses to Maryland and fostering a positive environment for those already in the state.

In a statement, O’Malley said he was “thrilled” with the move.

It is the latest turnover in the governor’s office for O’Malley, whose second and final term ends in January 2015. In recent months, O’Malley, who is weighing a 2016 presidential bid, has lost his chief of staff, chief lobbyist and director of public affairs as well.

Teddy Davis, who joined the governor’s office in February as its “strategic communications” director, is expected to take over many of Guillory’s responsibilities.

Guillory worked for O’Malley during his days as mayor of Baltimore. She served as communications director for Attorney General Douglas F. Gansler (D) before rejoining O’Malley in the governor’s office two years ago.
