Publicis Groupe is appointing Diana Littman as chief executive officer, U.S. for the Groupe's PR network MSL, replacing Ron Guirguis who departs after three years to pursue other opportunities. Littman joins from Marina Maher Communications where she was chief integration officer.

Unlike her predecessors, Littman will report directly to Arthur Sadoun, chairman/CEO of Publicis Groupe, and serve on the Publicis Groupe USA executive committee as Sadoun seeks to better integrate PR into the Groupe's broader Power of One strategy.  

“Building brand influence that drives impact for our clients is more critical today than ever," says Sadoun. "Within Publicis Groupe’s transformational model, MSL plays a vital role in delivering on this front. Diana is an exceptional leader, bringing a stellar track record, depth of expertise, breakthrough-thinking, and focus on results that will propel our clients and MSL USA forward."

Littman's day-to-day oversight will run across all of the network’s U.S. offices in Atlanta, Boston, Chicago, Detroit, New York, Seattle and Washington D.C. and span all facets of the company’s capabilities including corporate communications, consumer marketing, social purpose and sustainability, employee, and crisis/reputation management. 

The agency’s U.S. operation has 300 employees and the global network has more than 3,100 people across more than 107 offices.

Littman brings extensive consumer, healthcare and corporate marketing experience, including spending the past 11 years at MMC and a decade at Cohn & Wolfe.
