For decades, women have dealt cards or served drinks in casinos, but they rarely got the chance to run the joint. But women now run four of Atlantic City’s nine casinos in what some industry executives and observers say could be the future of the gambling industry. Caesars Entertainment hired Jacqueline Grace last week to run the Tropicana casino as its senior vice president and general manager. She is one of two Black women in charge of casinos in Atlantic City, joining Melonie Johnson, who took over leadership of the Borgata this year as its president.
