The Feb. 1 retirement of Susan Rosenbaum as director of Howard County's Department of Citizen Services has set in motion a chain reaction of promotions.
Department deputy director Lois Mikkila was named to replace Rosenbaum. Dale Jackson, who now runs the department's Office of Children's Services, will take Mikkila's post as deputy director, and Keri Hyde, director of the Howard County Children's Board, will take Jackson's post.
Rosenbaum, director since 2004, is retiring after 34 years with the county. Mikkila became her deputy in 2007, after years spent as a consultant and official of various nonprofits. She has lived in Howard County for nearly 30 years and will earn a salary of $127,858, county officials said.
