Tribal DDB New York confirms that managing partner Tim Pantello (pictured) and management supervisor Hillary Cooley have both left the agency. Pantello spent nearly five years at Tribal, and considering he joined the Digital Health Coalition, his move to take a leadership position come January at Digitas Health’s Philly HQ doesn’t look like the most illogical transition.

Cooley, meanwhile, spent four years at Tribal DDB NY, moving up from account executive to her most recent position. Like Pantello, she will assume a new job in 2012 as director of advertising at the American Precious Metals Exchange in Manhattan.  Spies add that management supervisor and four-and-a-half year Tribal NY vet Kim D’Aloise may have also left the agency, but we’ve yet to receive official word on that.
