In a management shuffle announced Feb. 6, Greenberg Traurig has promoted Miami shareholder Hilarie Bass to co-president, making her one of the highest-ranking women at a major U.S. law firm.

Bass moves up from global operating shareholder. She shares the presidency with Brian L. Duffy, a Denver shareholder who has been global litigation chairman. Cesar L. Alvarez and Matt Gorson move to co-chairmen from executive chairman and president, respectively. Firm CEO Richard Rosenbaum also named four vice presidents, including Ernest Greer, managing shareholder of the Atlanta office.
