Omnicom Media Group (OMG), the media services division of Omnicom Group Inc has announced that OMG CEO EMEA Guy Marks will succeed Philippa Brown as CEO of PHD Worldwide.

โGuy is one of our industryโs most entrepreneurial leaders, with an approach that transformed first OMDโs and subsequently Omnicom Media Groupโs offering in EMEA over the past six years,โ said OMG global CEO Florian Adamski. โBy enabling our agencies to quickly identify, adapt and respond in real time to the challenges of a dramatically changing consumer marketplace, heโs unlocked growth for our clients and made OMG the #1 media agency group for net new business in the EMEA region for the year-to-date, according to the most recent COMvergence reporting.
Adamski continues, โThe fact that – at the same time – he was also one of the networkโs key people coordinating Omnicomโs boots-on-the-ground Ukrainian relief and rescue efforts tells you everything you need to know about both his character and his leadership skills.โ
Brown, who has served as PHDโs global CEO since 2019, is stepping down following almost four decades in the media industry โ including 16 years in leadership positions with OMG – to focus on non-executive advisory roles at both the corporate and advocacy levels.
Commenting on Brownโs contributions, Adamski said, โAs CEO, Philippaโs passion for great work that advanced our clientsโ business goals was matched by her dedication to helping young talent advance their career goals. After leading the agency through the Covid crisis, she brought PHD back stronger than ever, earning Media Network of the Year honors at the 2021 Cannes Festival; winning Diageo, Chanel, Unilever, and most recently, the $300 million Grupo Bimbo account. She also launched and oversaw OMGโs Talent Management Community, an initiative offering professional development across the entire career life cycle.
โWe are deeply grateful for her tireless leadership, creative vision, and unwavering commitment to meeting the needs of her clients and her people, and we wish her all the best as she redirects her singular energy, experience, and expertise to an exciting new chapter in her career.โ
Marks joined OMG in 2014 following Omnicomโs acquisition of Mobile5, the global UX, design and tech consultancy service that he co-founded. As CEO of OMG EMEA, he helped establish Omnicomโs Transact connected commerce and retail media consultancy in the region; and co-architected the expansion of OMGโs TRKKN analytics and cloud consultancy from five European countries to 20 markets across APAC, EMEA and North America.
โThe thread that can be pulled through all my professional experience is driving growth through transformation,โ said Marks. โAs the CEO of PHD – an agency that was born from a transformative concept of media as a strategic tool – my priority will be assuring that every PHD account team around the world have the talent, tools, technology and collective commitment to excellence they need to deliver the transformative ideas, solutions and service that drive growth for our clients, our agency, and our people.โ
Marks, whose appointment is effective October 1, will be headquartered in London, reporting to Adamski. His successor as leader of OMG EMEA is expected to be named next week.
