Mariana O’Kelly is joining Leo Burnett Chicago as Executive Vice President/Executive Creative Director.

O’Kelly reports to Britt Nolan, President-Chief Creative Officer, and is charged with running the Kellogg’s portfolio for the agency. The client relationship began in 1949.

Previously, she was executive creative director at Ogilvy, South Africa, before moving to Ogilvy Chicago as Global Executive Creative Director in 2019.

Britt said O’Kelly had a “reputation for growing world-class teams.”

Two week ago, Leo Burnett Chicago retained the top spot in The One Club For Creativity’s Global Creative Rankings 2022. The agency’s performance is largely based on wins for “The Lost Class” on behalf of Change the Ref.
