Another Tribal SF departure, you say? Well, after two tours of duty at Tribal DDB, the last one being a two-and-a-half year stint as both president of U.S. operations and managing director of the network’s Bay Area branch, Mike Parker is now leaving the agency. Sources familiar tell us that Parker is winding things down over the next few days at Tribal and eventually heading over to McCann Erickson’s San Francisco branch to take on the role of chief digital officer. No official date, though, has been set for Parker’s arrival at McCann.

The exec’s relationship with Tribal dates back to 2000 when he joined up with the agency’s Canadian operations, where he spent seven years and last served as managing director. In between his two stints at Tribal, Parker spent two years as director of digital strategy at Goodby.
