Ken Berger joined Charity Navigator in 2008 after almost thirty years experience working in the charitable non-profit sector. He has held leadership positions at a variety of human service and health care agencies, both large and small, and has operated programs serving many underserved populations including the homeless, the developmentally disabled, the mentally ill, substance abusers, the medically needy, and persons with HIV/AIDS, among many others. Ken earned his Bachelor's degree at the University of Buffalo. He went on to obtain a Master's degree in Psychology from Antioch University and a Master's degree in Business Administration from Rutgers University. Ken has a deep passion for helping donors become wise social investors (charitable givers who see their donations as a long term social investment) by learning how to identify and then support high performing nonprofits. He also has a deep interest in encouraging charitable non-profits to perform effectively and thrive even in challenging times. He is a regular presenter at conferences on both the domestic and international stage, is frequently interviewed by regional, national and international media on nonprofit issues and has published numerous articles on issues affecting the nonprofit sector's effectiveness. In addition, he is the author of Ken's Commentary, a blog about his thoughts on the non-profit sector. He is a member of the Alliance for Effective Social Investing and was a founding member of the Social Impact Analysts Association. He was also a member of the CFC-50 Commission which was formed under the U.S. Office of Personnel Management to strengthen the integrity, operation and effectiveness of the Combined Federal Campaign (the largest workplace giving campaign in the world).
