NEW YORK, USA – Omnicom Media Group’s (OMG) flagship agency OMD has named Ellen Griffin as President and Global Chief Operating Officer, a newly created role designed to spearhead the development and deployment of customized, future ready operating models across its worldwide client portfolio.
The appointment underscores OMD’s commitment to its brand promise, “We create what’s next,” and reflects the agency’s focus on enabling brands to thrive in an increasingly complex marketing landscape.
Griffin, formerly OMD’s Global Chief Client Solutions Officer, will leverage the collective capabilities of OMG and the broader Omnicom network spanning media, data, CRM, commerce, content and creativity to help clients navigate transformation and drive 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.”
Since joining OMD in 2018 as Global Innovation Director, Griffin has been at the forefront of shaping the agency’s model, talent and capabilities. As Global Chief Client Solutions Officer, she played a pivotal role in designing bespoke 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, reporting directly to Manas.
Her appointment follows a string of global accolades for OMD: the agency was recently named #1 media agency globally in the COMvergence Global & Regional Billings report, with $23.6B in worldwide billings, and earned Media Network of the Year honors at the 2025 Cannes Lions—its third win in four years, and second in a row.
