There’s a reason why Bobby Hershfield is all smiles judging by his headshot as the four-year Mother employee has been promoted to group creative director at the agency’s New York office. During his tenure at Mother, Hershfield has worked on accounts including J&J, Target, Sweet ‘N Low and Tanqueray. Prior to joining the Mother-ship, the creative spent two years at Ogilvy and worked on IBM and Yahoo and spent nine years at W+K before that. In a statement, his boss, Mother founding partner Paul Malmstrom, says “Bobby has been one of the fine ingredients in the Mother pancake we haven’t talked that much about. From today, we add an additional teaspoon of Hershfield, and smile.” Yeah, we get the “smile” part.
