Omnicom Public Relations Group

One of the world's largest PR networks, significantly expanded through the Omnicom-Interpublic merger to include Weber Shandwick alongside FleishmanHillard, Ketchum, and Porter Novelli

Omnicom Public Relations Group (OPRG) is the public relations and communications division of Omnicom Group, one of the world's largest advertising and marketing services holding companies. Led by CEO Chris Foster, OPRG encompasses a portfolio of some of the most recognized PR agency brands globally, including FleishmanHillard, Ketchum, Porter Novelli, and — following Omnicom's acquisition of Interpublic Group — Weber Shandwick, one of the world's largest PR firms. This consolidation makes OPRG arguably the largest PR network in the world by headcount and revenue. OPRG agencies collectively serve Fortune 500 companies, government entities, nonprofits, and emerging brands across virtually every industry sector. Their capabilities span corporate communications, crisis management, public affairs, brand strategy, digital and social media, healthcare communications, and integrated marketing. The group operates across dozens of countries, providing both global scale and local market expertise. The addition of Weber Shandwick and other IPG PR assets through the Interpublic acquisition significantly expanded OPRG's footprint and talent base, intensifying competition with rival PR networks such as Edelman, WPP's BCW (now Burson), and Publicis Communications. OPRG represents a critical pillar of Omnicom's broader integrated marketing services offering, enabling cross-disciplinary collaboration between PR, advertising, media, and data analytics.
