Aaron Walton, co-founder, Walton Isaacson

The co-founder of 14-year-old agency Walton Isaacson first went to work for the brand side in 1983 — Pepsi specifically. As it happens Pepsi at the time was working with a singer by the name of Michael Jackson. Walton's job would take him on tour with Jackson. Now, some 35 years after that first incredible gig, Walton is not only still in the business of telling brand stories, he's still at culture's cutting edge. It was Walton Isaacson client Lexus that teamed up with Marvel for the Black Panther ads that ran during this year's Super Bowl. More recently the agency added the New York Police Department to its roster, where the mandate is to help the department integrate its ranks.
