In this article the authors present the full interview conducted with George Grob in 2011 at the American Evaluation Association (AEA) Conference in Anaheim, CA. George Grob is former Director of the Office of Evaluation and Inspections in the Office of Inspector General. Prior to serving in that Office, he was Director of Planning and Policy Coordination in the Department of Health, Education, and Welfare (HEW). Grob's career in public service is noteworthy for its productivity and policy impact. Under his direction, the Office of Evaluation and Inspections produced a remarkable number of evaluation studies, numbering over 1,000. Grob and his staff have had positive impact on a wide range of national policies and initiatives from nursing home care to child support enforcement to human tissue transplants to anti-bioterrorism. Reflecting his long-standing belief in the importance of mentoring others, he continues to train junior evaluators who work in a variety of federal agencies. Indeed, contributing to the development of the next generation of public services evaluators is among his greatest passions. In the edited transcript that follows, Grob describes his path from his first internship at the Department of Defense to Directorship of the Office of Evaluation and Inspections. Grob's unwavering belief in the potential of every person to make a positive impact on government and his indefatigable excitement about learning from every new situation he encounters are keys to his long, successful public service career.
