Omnicom Media Group (OMG) announced on Tuesday a significant leadership transition at PHD Worldwide, one of its core media agencies. Guy Marks, who has been serving as CEO of OMG's Europe, Middle East & Africa (EMEA) region, will take over from Philippa Brown as CEO of PHD Worldwide effective Oct. 1.
Marks joined OMG in 2014 following Omnicom’s acquisition of Mobile5, a global UX, design, and tech consultancy service that he co-founded. As CEO of OMG EMEA, he played a crucial role in establishing Omnicom’s Transact connected commerce and retail media consultancy in the region. He also co-architected the expansion of OMG’s TRKKN analytics and cloud consultancy from five European countries to 20 markets across APAC, EMEA, and North America.
Florian Adamski, OMG's global CEO, praised Marks for his transformative approach that has driven growth for the agency's clients and made OMG the top media agency group for net new business in the EMEA region year-to-date, according to COMvergence. Adamski also highlighted Marks' role in coordinating Omnicom’s Ukrainian relief and rescue efforts as indicative of his leadership skills.
Philippa Brown is stepping down after almost four decades in the media industry to focus on non-executive advisory roles at corporate and advocacy levels. Brown served as PHD’s global CEO since 2019 and led the agency through the Covid crisis, bringing it back stronger than ever.
Adamski also credited Brown with launching OMG’s Talent Management Community, an initiative offering professional career development within the company. "We are deeply grateful for her tireless leadership, creative vision, and unwavering commitment to meeting the needs of her clients and her people," said Adamski.
Marks will be based in London in his new role as CEO of PHD Worldwide and will report to Adamski. His successor as leader of OMG EMEA is expected to be named next week.
