Jef Moore is being promoted to senior vice president, chief creative officer at Mosaic.

Moore takes on expanded North American creative leadership as Mosaic grows its creative team across Canada and the U.S.

Justine Greenwald served as Mosaic’s previous CCO, departing the agency in early 2025.

Moore joined Mosaic as a copywriter 12 years ago and has risen through the agency’s creative ranks, most recently serving as vice president, executive creative director. Over the past year, his remit has expanded from leading the Canadian creative team to overseeing creative and design across Canada and the U.S., including design and production design.

Moore also led Mosaic’s spring agency-wide evolution and rebrand, “Where Every Piece Stands Out,” which repositioned Mosaic from an XM shop to a broader brand experience agency.

“Jef understands that great creative work isn’t just about ideas. It’s about creating experiences that move consumers, strengthen brands and deliver business results,” says Todd London, president, Mosaic North America. “His ability to bring together strategy, creativity, operations and client partnership has made a lasting impact on Mosaic.”

“I’ve always believed the best work happens when you put talented people in the right environment to succeed,” said Moore. “Bringing our strategy, creative and design teams together across North America gives us one cohesive vision that has become our mandate: to do work that will stand out.”

Marisa Faustino has been promoted to group creative director, overseeing integrated commerce, while Dan Berzen has been promoted to group creative director, overseeing the experience portfolio and leading innovation, AI and technology initiatives.

The agency has also added James Kirchner as creative director, B2B; Darren Marranca as associate creative director, integrated commerce; Matt Camara as creative director; and welcomed back Julia McCrae as senior designer.

Mosaic added new clients including BMO, OtterBox and Nespresso U.S. XM, while expanding its work with existing partners including ESPN, Buffalo Bills, LEGO, Labatt, Google and Verizon.
