After a three-year absence, Davide Rettore will be returning to the Marcolin Group as chief executive for North America. Marcolin's U.S. business has been without a CEO since January, when Fabrizio Gamberini departed. Rettore returns from Kering Eyewear, where he served as global brand director. North America is a key market for Marcolin as it represents almost 45 percent of its global sales. Rettore previously worked as brand manager for two licenses of Marcolin, Roberto Cavalli and Just Cavalli. He also spent two years as Marcolin's group brand manager.
