New York: Omnicom Media Group (OMG) agency OMD has announced the appointment of Ellen Griffin as President, Global Chief Operating Officer — a newly created role aimed at accelerating the development and adoption of customized, future-ready operating models for the agency’s global client portfolio.
Griffin, who most recently served as OMD’s Global Chief Client Solutions Officer, will leverage the breadth of capabilities across OMG and the wider Omnicom network to help brands navigate business transformation and unlock marketing-led growth.
“Earlier this year, OMD made a bold new promise: We create what’s next,” said OMD Worldwide CEO George Manas. “With this new role, we’re delivering on that promise by building solutions that tap into Omnicom’s full advantage across media, data, CRM, commerce, content, and creativity. Ellen brings the vision and operational leadership to help our clients win in an increasingly complex and challenging business environment.”
Joining OMD in 2018 as Global Innovation Director, Griffin went on to become Global Chief Client Solutions Officer, where she played a pivotal role in evolving OMD’s model, talent, and capabilities. She was instrumental in designing custom client solutions powered by Omni — Omnicom’s global marketing intelligence platform — contributing to more than $2.5 billion in net new business wins.
Commenting on her new role, Griffin said, “In a time of accelerated disruption, even the most seasoned marketers are challenged to keep pace. This role is about accelerating and scaling transformation—ensuring OMD delivers the expertise, tools, and operating models that give our clients a competitive edge today and resilience for tomorrow.”
Her appointment is effective immediately and she will report directly to Manas.
The announcement follows a series of global accolades for OMD, including being ranked the #1 media agency worldwide in the COMvergence Global & Regional Billings report with $23.6 billion in billings, and securing Media Network of the Year at the 2025 Cannes Lions — its third win in four years and second consecutive title.
