Matt Ryan, global CMO of Euro RSCG, has risen to president of global brands for the shop and global CMO of corporate parent Havas Worldwide.
Filling the agency CMO role is Naomi Troni, who previously was Ryan's No. 2, as global new business director. Both executives will continue to be based in New York.
The moves "reflect a period of major successes and expansion," with Ryan (pictured) and Troni making major contributions, according to a Havas statement.
During Ryan's two years as CMO of Euro RSCG, the agency won U.S creative and digital duties on Heineken, global digital duties on IBM.com and global creative duties on Pernod Ricard's Jacob's Creek, among other assignments.
Last year, Unilever also added Euro RSCG to its roster of digital agencies.
As president of global brands, Ryan fills a vacancy created in February when Pete Zillig became co-CEO of the shop's New York office, succeeding Andrew Benett, who shifted to global CEO of sister shop Arnold.
In this role, Ryan, 49, will oversee management of worldwide accounts and seek new global business. The shop's largest clients include Kraft and Nestle.
Other executives who have held this role in the past include David Jones, now global CEO of both the agency and Havas, and Esther Lee, who also was North American CEO and left the shop in 2008.
As Havas CMO, Ryan will counsel the company's creative agencies on their pursuit of new business and manage so-called holding company pitches.
Troni, 33, had been global new business director since 2008. Before that, she was client development director at Euro RSCG in London and business development director for the U.K. region. Troni has worked at the agency since 2004.
Reflecting on Ryan and Troni, Jones said: "They are two of the company's brightest stars and these appointments reflect their achievements and our ambition."
Havas this week reported improved financials for Q1 after recent declines.
