Wieden+Kennedy Amsterdam has promoted Clay Mills to Managing Director. He follows up Lee Newman, who was appointed as MD in 2008. Newman will become president at O&M Chicago. Mills was hired by Wieden in 2010 as Group AD on Heineken. Since his hiring Heineken became one of Wieden’s more profitable and successful accounts, making the agency even lead this year’s Gunn report. Prior to W+K Amsterdam, Mills worked at JWT New York, and BBH in New York and London. ECD’s Mark Bernath and Eric Quennoy about Mills’ appointment: “Spending the last two years making the Heineken work with Clay has been one of the more enjoyable experiences of our careers. You have to work with people who make work feel more like having fun. That’s when the best stuff happens. Of course, you can’t have fun without being dead serious and smart about what you’re doing. A balance that Clay gets as good as anyone.
