Capricia Penavic Marshall spoke to Bill Wills about her new book Protocol: The Power of Diplomacy and How to Make It Work for You. Capricia, President Obama’s former United States chief of protocol looks at why diplomacy and etiquette matter—from the international stage to everyday life. History often appears to consist of big gestures and dramatic shifts. But for every peace treaty signed, someone set the stage, using hidden influence to effect the outcome. In her roles as chief of protocol for President Barack Obama and social secretary to President Bill Clinton and First Lady Hillary Clinton, Capricia Penavic Marshall not only bore witness to history, she facilitated it. From arranging a room to have an intended impact on the participants to knowing which cultural gestures earned trust, her behind-the scenes preparations laid the groundwork for successful diplomacy between heads of state around the world and tilted the playing field in her team's favor.
