Grand Plan: Help brands and celebs effect social change. 

Making Headlines: The Propper Daley agency has landed on the speed dial of many a Hollywood star and exec thanks to its founders' expertise in politics, business, and the nonprofit sector. Clients range from Bradley Cooper (eradicating blood cancer) to John Legend (ending mass incarceration) to the Clintons (the agency helped their foundation's Too Small to Fail initiative integrate content about the importance of reading and talking to infants into TV shows like Orange Is the New Black).

She also displays an impressive nose for talent: Beneficiaries have included Oscar Isaac, Cary Fukunaga, and Leslie Odom Jr.
