Arnold N.Y. Hires Staffen as ECD

Former DDB creative John Staffen last week joined Arnold in New York as its executive creative director, the agency said. Staffen, 43, took over the Havas shop’s 50-person creative staff from Rochelle Klein, who left in November. Staffen was co-ecd of Omnicom’s DDB in New York before leaving in October. (He had three other stints at DDB before his most recent post.) Arnold failed to convert on several pitches last year, and president Mary Baglivo said Staffen’s task is to help “win a few big ones.”
