Top Phillips rainmakers Cheyenne Westphal and Jean-Paul Engelen to leave auction house

Two top executives at Phillips auction house, global chairwoman Cheyenne Westphal and president of the Americas Jean-Paul Engelen, are stepping down. Westphal, who joined Phillips from Sotheby's in 2016 and has been called the most powerful woman in contemporary art, plans to start her own business working directly with private collectors and artists. Engelen is moving to Acquavella Galleries in New York. Their departures follow the resignation of executive chairman Ed Dolman in December and deputy CEO Amanda Lo Iacono at the end of last year, marking a significant leadership exodus.
