Having spent the past 15 years studying women leadersand building Most Powerful Women into Fortunes second-biggest brand, after the Fortune 500Pattie Sellers has gained unparalleled access to Americas top women leaders and has keen insights into what makes women successful (and not) in business, philanthropy, government and beyond.
