Bio
John Wren is the Chairman and Chief Executive Officer of Omnicom Group Inc., the world's largest advertising and communications holding company by revenue. He entered the advertising industry in 1986 as a senior vice president of finance and administration at DDB Needham Worldwide, which that same year became part of the newly formed Omnicom holding company. He subsequently served as CEO of Omnicom's Diversified Agency Services division, then as president of Omnicom Group, before being named CEO in January 1997. When his mentor Bruce Crawford stepped down as chairman in 2018, Wren added that title to his role. In November 2025, Omnicom closed its $13.25 billion acquisition of Interpublic Group, producing a combined entity with pro-forma annual revenue of approximately $25 billion — making Omnicom materially larger than WPP, Publicis Groupe, and Dentsu at the holding-company level.
