Interpublic’s McCann Worldgroup is reshuffling the leadership at its Detroit operations and giving its dedicated Chevy agency a new name.   

Commonwealth//McCann, the dedicated Chevrolet agency, will be renamed McCann Detroit. The old name is a throwback to the origins of the agency when it was a joint venture with Goodby Silverstein & Partners. Earlier this year the agency laid off a number of its Detroit staff.  

As part of the reorganization, Grant Theron, who previously served as global CEO of Commonwealth//McCann and led the company’s General Motors business globally, has been appointed global CEO of MRM, MWG’s customer relationship agency.    

Theron succeeds Kate MacNevin who will continue as global chair of MRM, in addition to her role as global chief operating officer of McCann Worldgroup.   

Taking over Theron’s responsibilities on GM will be Belinda Leworthy, who has been elevated to a dual role of global business lead for GM and president, McCann Worldgroup Detroit. She previously led Commonwealth//McCann’s North America operations.   

Theron and Leworthy are both based in Detroit. While McCann has made significant layoffs in the market this year, global CEO Daryl Lee indicated in a statement that with the reorganization, “we reaffirm our commitment to this important market.”
