Weber Shandwick

One of the largest global PR networks by revenue and geographic reach, now integrated into Omnicom's consolidated PR group

Weber Shandwick, now operating within Omnicom's unified public relations group following the completion of the Omnicom-IPG mega-merger, is one of the world's preeminent global public relations and communications agencies. The firm was formed in 2001 through the merger of The Weber Group and Shandwick International, two established PR powerhouses, and grew under the Interpublic Group (IPG) umbrella to become a flagship network known for its creative, data-driven communications work. With offices spanning more than 80 countries, Weber Shandwick serves a broad range of multinational clients across corporate, consumer, healthcare, technology, and public affairs sectors. The agency has long been recognized for its integrated approach to communications, blending traditional media relations with digital strategy, content creation, influencer marketing, crisis management, and social impact work. Its proprietary tools and analytics capabilities have helped distinguish it in a competitive landscape, enabling clients to measure and optimize earned media performance alongside paid and owned channels. Weber Shandwick has consistently ranked among the top PR firms globally by revenue and has accumulated numerous industry accolades, including repeated recognition as PRWeek's Global Agency of the Year. Following the EU's clearance of the $13 billion Omnicom-IPG combination, Weber Shandwick was folded into Omnicom's consolidated PR structure, which unifies several major PR networks under a single organizational umbrella. Despite leadership transitions — including the departure of longtime CEO Jim O'Leary — the Weber Shandwick brand has continued to operate as a distinct entity within the Omnicom ecosystem, maintaining its global footprint and client relationships while adapting to its new corporate home.
