A decade ago, Thomas J. Tierney left Bain & Company to cofound The Bridgespan Group, a nonprofit focused on helping donors and nonprofit leaders to develop and execute strategies to accelerate social change. In Give Smart, Tierney pools his hands-on knowledge with Duke professor Joel L. Fleishman’s expertise to create a much-needed primer for philanthropists and the nonprofit organizations they support. Drawing from personal experiences, research spanning twentieth- and twenty-first-century philanthropy, contemporary interviews, and Bridgespan’s extensive field work, Give Smart presents the definitive guide to engaged philanthropy.
