Changing behavior through the power of creativity since 1935

Leo Burnett exists to be the ultimate partner in the creation of ideas and brands that truly move people. We believe that every great brand has purpose, and when we combine this sense of purpose with an obsessive attention to people and their behavior, we create more than just ads – we create acts. Acts are human centric brand ideas, gestures or experiences that have the ability to transform the way a person thinks, feels and ultimately behaves.

Our Chicago roots continue to shape our culture. From the city that first split the atom and invented the skyscraper comes a population of dynamic dreamers with ideas that change the world. That’s why in 2008 Leo Burnett was the most-awarded agency in the “All Gunns Blazing” category of the Gunn Report. We create meaningful results for our clients. In fact, Leo Burnett was the most effective agency for 6 consecutive years (2001-2007), winning more Effies than any other agency.

Leo Burnett opened its doors on August 5, 1935, in the midst of the Great Depression, and we’ve been helping clients like Kellogg, Proctor & Gamble, and McDonalds thrive during tough times ever since. Perhaps that’s why the average tenure of these client relationships is 47 years.
