Sources familiar with the matter confirm that Tamy Harms, who’s spent the last eight-and-a-half years at Digitas’ Detroit office, most recently as SVP/managing director, has “decided to pursue other opportunities outside the agency.” Harms joined Digitas in 2004 as VP/marketing and subsequently moved up to SVP four years later. Prior to Digitas, Harms spent nearly four years at Carlson Marketing Group (which rebranded under the name Aimia last year), where she led strategic planning for various GM brands.
