What drives social change? Big Impact is about change-makers who have found solutions to some of society's greatest, most vexing problems. These dynamic leaders are implementing solutions in their communities, across the U.S. and around the world. It also explores the qualities these leaders possess, their profound insights on lessons learned, and the solutions they are implementing.

Authors Vivien Hoexter and Linda Hartley interviewed nearly 50 leaders of organizations such as the Rockefeller Brothers Fund, William and Flora Hewlett Foundation, Skoll Foundation, PBS, Nature Conservancy, Goodwill Industries International and Share Our Strength.

The book combines the authors' findings and recommendations from the interviews on what drives social change, along with some of the top interviews portraying compelling, successful social change leaders. Hartley and Hoexter see this book as a way to amplify the leading voices of the nonprofit sector, to share the secrets of successful social change and to inspire readers to make change in their own communities.
