As CEO of one of the PR industry's largest agencies, Marcia Silverman has been an example of how to run a firm. Under her leadership, Ogilvy has continued to thrive on the global stage, representing a diverse list of corporations, governments, and nonprofits. The agency is particularly strong in establishing multiple-year relationships with federal agencies, such as the CDC and The National Heart, Lung, and Blood Institute. She has been with the agency for more than 20 years, assuming the CEO role in the wake of the dot-com bust (taking over in 2002 after Ogilvy's revenues plunged 26% compared to the previous year). Silverman is also big on philanthropy, serving on the boards of the Women's Campaign Fund and the Mexican American Legal Defense and Education Fund. She has also won a number of honors, including being named one of Washington Business Journal's "Women Who Mean Business."
