Stephen Badger serves as Chairman of Mars, Incorporated’s Board of Directors. He was a key investor in Seeds of Change, an organic seed and food company, and also served as President. As Global Director of Corporate Affairs, Badger led Mars to be the first company among its food and confectionery peers to eliminate marketing its products to children under 12, a move which has since shaped industry-wide practices. Badger also financed and produced the film Muscle Shoals which premiered at Sundance to a standing ovation in 2013.
