Bill Dietel has 50 years of experience consulting foundations, organizations, families and individuals about philanthropy.
He believes that the services that we provide today are more important than ever. At a time when government, at all levels, is increasingly sclerotic, nonprofits have a unique opportunity to provide creative leadership. But, to realize the full potential of that leadership, the sector needs philanthropic financial support.
Bill is a former teacher, principal and dean who entered philanthropy in 1970 with the Rockefeller family. He served as Executive Vice President and President of the Rockefeller Brothers Fund from 1970-87. In 1987, he established a consulting practice that became Dietel Partners in 2007 when his daughters joined the firm.
He retired from full partnership in 2016 and now advises the organization on select matters concerning philanthropic strategy, client relationships, governance and institutional strengthening.
Prior to serving the Rockefeller family, he was Principal of the Emma Willard School in Troy, New York for nine years. Before that he served as Assistant Dean and Assistant Professor of the Humanities at Amherst College, after teaching history at the University of Massachusetts, Amherst.
Bill earned a PhD and MA from Yale University, and a BA in the Special Program in the Humanities from Princeton University. He is a graduate of the Phillips Exeter Academy.
