It looks like Goodby Silverstein & Partners is set to lose another longtime staffer. Just a day after reporting that Linda Harless was leaving the agency after 25 years, we’ve received confirmation from sources familiar with the matter that GS&P ACD/copywriter Craig Mangan is also taking off to join up with sister Omnicom shop BBDO as the new EVP/ECD of its San Francisco office.

Mangan, who will assume his new position at BBDO SF in the first week of July, succeeds Mike McKay, who left the agency last fall for the CCO job at fellow Bay Area operation, Eleven. BBDO San Francisco’s soon-to-be creative boss, who will lead creative for clients including Gallo, Mars, Caesars Entertainment and Vail Resports, spent approximately 16 years at Goodby, moving from the account side to creative over a decade ago. Mangan subsequently penned work including the memorable split-screen spots for the NBA from a few years ago. If you need a refresher (and since they’re currently battling in a series right now), here’s one example starring LeBron James and Kevin Garnett. Update: After the jump, you can peep the short ‘n sweet note from BBDO SF chairman Jim Lesser that confirms matters.

Gang,

Craig Mangan is our new ECD.

He’s been at Goodby for 17 years.

Yes, really.

He’s worked on a huge range of accounts from fast food to telecom to the NBA and won every award there is to win.

He’s an awesome guy and a great talent and he’ll be starting at the beginning of July.

Onward.

Jim
