Industry veteran Don Parkinson retired April 1 as Monte Carlo and Impala brand manager. His successor, Jim Campbell, was formerly the S-10 pickup manager. Ed Schoener moves from Avalanche to Malibu. Russ Clark, already on TrailBlazer, adds Avalanche.
GM said earlier this year it plans to reduce the number of brand managers.
Separately, Patrick Harrison retired from GM after 30-plus years. He joins Interpublic Group of Cos.' McCann-Erickson Worldwide's Naperville, Ill., office as the Buick account supervisor for the North Central region.
Mr. Harrison supervised training in the region in his last GM post, but his career there included regional Cadillac marketing manager, Buick zone manager and national assistant brand manager of Buick's Park Avenue.
