PARIS — LVMH Moet Hennessy Louis Vuitton-owned Guerlain continues to generate news of changes at the top.

Just days after WWD learned of the retirement of the company’s in-house perfumer Jean-Paul Guerlain, the great-great-grandson of the company’s founder, Guerlain announced that Renato Semerari has been named president and managing director of the firm. He will replace Thibault Ponroy, who has resigned.

Semerari will take over his new duties Thursday. He joined LVMH-owned Parfums Christian Dior as international marketing director in November 1999. Prior to that, he was at Procter & Gamble from 1986 to 1999.

“Renato Semerari has done extremely well at Christian Dior for a couple of years,” Patrick Choel, president of LVMH’s fragrance and cosmetics division, told WWD Monday. “[The new position] is a natural promotion for him.”

Neither Semerari nor Ponroy could be reached for comment.

Elsewhere at Guerlain, Laurent Boillot has been named associate managing director in charge of international marketing, a new post. He also starts Thursday.

From 1990 to 2001 he worked at Unilever, most recently as the director of marketing and development in Europe for hair care.

Meanwhile, at Dior, Sabina Belli will replace Semerari as international marketing director. She will leave her position as marketing director of fragrances, which she held since 1996, but will retain the title of director of development for fragrance licenses at LVMH.

Thomas du-Pre de Saint Maur, meantime, will become marketing director of fragrances at Dior.
