United States – Dentsu Creative has appointed John Mescall as its new global chief creative partner, a move that signals the network’s continued focus on creative development at an international level.

Mescall, who will be based in New York, will work alongside Yasu Sasaki, global chief creative officer at Dentsu, to strengthen creative alignment across markets. His remit includes supporting the network’s global creative community, integrating emerging technologies such as AI into creative workflows, and fostering talent development across regions.

“What drew me to Dentsu Creative is its deep belief in the power of creativity to drive meaningful impact across the board,” said Mescall. “It’s rare to find a global organisation so aligned in purpose, yet so attuned to the unique strengths of its local teams. I’m excited to be a part of a creative culture full of talented, passionate people, that values excellence, fosters innovation, and puts humanity at the centre of everything we do.”

Mescall brings a long track record of creative leadership, previously serving as global executive creative director and president of the global creative council at McCann Worldgroup, as well as chief creative officer of McCann Melbourne.

“John’s creative legacy speaks for itself, but what excites us most is his ability to unite teams around a shared vision,” said Abbey Klaassen, global president of Dentsu Creative.

“He knows how to translate big ideas across markets, unlocking the strongest creative thinking from each region. As a champion of evolution and transformation — not just in the work, but in how we work — John will play a pivotal role in driving creative alignment, elevating our craft, and delivering work that’s both culturally resonant and strategically unified, as we continue to scale our creative impact.”

Yasu Sasaki added: “Transformative Creativity is the driving force that connects our network’s capabilities to create meaningful impact for people, businesses, and society, and John’s commitment to creativity is a reflection of that.”
