Karen Costello is returning to Deutsch Los Angeles for the second time, this time to serve as CCO. She arrives with decades of agency experience, after initially joining as one of its first creative hires in 1997.

She joins the agency after over three years with The Martin Agency as executive creative director, leading the Mondelēz account in 2017. She had been promoted to CCO the next year.

Costello told Adweek that the move was “bittersweet,” as she considered the team at The Martin Agency to be like family.
