“What helps people helps business.”

Guided by these words of our founder, we’ve never lost sight of what, for us, is the plainest truth in the world: clients grow their business by creating value for the people they serve.

Helping people has paid off.

Ad Age named us an “Agency to Watch” in 2019, and three of our clients (Samsung, Nintendo and Coca-Cola) have recently appeared on the publication’s “Marketer of the Year” list. We’ve been recognized for 422 prestigious global awards over the last two years and seven Cannes Grand Prix in the past decade; were ranked No. 1 for retail specialty by WARC two years in a row; and were named “Agency of the Year” in 2020 by the American Advertising Awards.

And what Leo started in 1935, in a Chicago hotel suite with eight employees, has grown into an always-evolving agency with a full suite of integrated services and 59 offices across 49 countries.
