Conill Advertising, the Hispanic agency owned by Saatchi & Saatchi, has reached within the ranks of its parent network to find a new chief creative officer. Mariano Favetto, a multiple Gold Lion winner and most recently creative director at Lautrec Nazca Saatchi & Saatchi in Buenos Aires, Argentina, replaces Luz de Armas, who left Conill here in November. Favetto starts his new job today. “I think there’s lots of room for growing and for doing great advertising,” said Favetto, 31. “Basically, [in coming to New York] I decided to make a big life change.” Favetto will work closely with shop president Nancy Pendas-Smith and Elias Weinstock, creative director at Conill’s office in Torrance, Calif. “We both share the same passion for advertising,” Pendas-Smith said of Favetto. “Advertising is emotional. It’s about the consumer.” Favetto won his first Gold Lion at Cannes in 1996 for a Sony home electronics print ad. He claimed his second gold last year for a 40-second TV spot for Consolidar pension funds. Conill has billings of about $33 million and clients such as Procter & Gamble, Bell Atlantic and Toyota. Separately, Chase Manhattan Bank last week hired the shop to do its ethnic direct marketing and promotion work on a project basis, said Howard Cutler, Chase’s vice president, communications services and marketing. Spending was not disclosed.
