Article content
Elizabeth Harris has expanded her remit to Head of Client Operations UK across the broader Omnicom Media Group portfolio, marking a significant leadership expansion across some of the industry’s leading media agencies.
In addition to her continued work with UM London, Initiative UK, and Mediahub Worldwide, Elizabeth will now also support agencies including PHD, OMD UK, Hearts & Science, and MG OMD.
Her expanded role reflects the growing importance of integrated operational leadership as media organizations increasingly align cross-agency collaboration, client delivery, technology operations, and workflow management across larger network ecosystems.
As media, data, AI, and customer engagement strategies continue converging, operational leadership is becoming increasingly central to how agencies scale efficiency, maintain consistency, and support enterprise client relationships across multiple business units.
Omnicom Media Group continues evolving its operational and agency structures to support increasingly connected media ecosystems where collaboration, agility, and integrated client experiences are critical competitive differentiators.
Elizabeth’s expanded remit highlights how operational leadership is now playing a far more strategic role in driving agency transformation, cross-functional alignment, and long-term client success.
