CEO Brian Morris, a 26-year veteran of the agency, has been replaced by Vice Chairman Bruce Miller, 54. Mr. Miller's former agency, Suissa Miller, was purchased by Interpublic in 2000 and later merged with Dailey.
Upper-level management will remain the same: Cliff Einstein continues as chairman and will still work on the agency's anchor client, Southern California Ford Dealers, and Steve Rabosky, who was hired in March, remains president-chief creative officer.
Dailey's clients include Princess Cruises, Intuit, Nestle and Weyerhaeuser.
Mr. Morris, who has been active in the Los Angeles agency community and was the area's advertising association leader of the year, could not be reached for comment.
