MayoSeitz Media (MSM) has announced new branding to showcase the word media.

“These are more than symbolic changes,” said Ray Mayo, co-founder of MSM and now Chief Executive Officer. “They reflect the agency we’ve become — agile, data-driven and focused on meaningful outcomes for our clients. We’re building on a strong foundation, led by extraordinary people and driven by a bold vision for what’s next.”

Will Nathanson, a former director of brand strategy for Red Tettemer O'Connell + Partners, designed the new logo.

The visual refresh is accompanied by changes to the executive team, promoting seasoned staffers. 

Mary Tyrrell, an MSM vet, has been named President-Chief Operating Officer. She has been with the agency for 21 years in a variety of roles. Jon Seitz, a managing director, has moved into the General Manager role, overseeing IT, PR and AI integration. He joined MSM in 1997.

The paid media agency's client roster includes NovaCare, Penn Medicine, Citadel Credit Union, The Society of Actuaries and The Florida Aquarium.
