Jordi Constans stepped down from his position as chief executive of Louis Vuitton due to medical reasons, just one month after taking over from Yves Carcelle, who helmed the French house for more than two decades and is currently serving on LVMH's executive committee. Constans, who first joined Vuitton in September 2011, has been replaced by Michael Burke, former chief executive of Bvlgari and a longstanding member of LVMH's staff. Burke is an American executive who started his career with the French conglomerate in 1980, working at various other firms controlled by Bernard Arnault before joining Christian Dior in the U.S. in 1986. He was president and chief executive of Louis Vuitton North America from 1993 until 1997. In that capacity, he oversaw the construction of the LVMH building on 57th Street in New York. He was then named worldwide managing director of Christian Dior Couture, but moved to run Fendi in 2003. He joined Bvlgari last February, soon after its takeover by LVMH.
