David’s career is centered on helping effective change makers increase their positive social impact. With more than 25 years of experience working with organizations in the nonprofit, public, and private sectors on assessing the social value they create and finding ways to improve it, his work demonstrably and measurably drives initiatives towards ‘what actually works’. As an economist and consultant for public and nonprofit organizations in New York City, Washington, D.C., London and Luxembourg David evaluated and modeled programs to ensure they were an efficient and sustainable use of public and philanthropic resources. In recent years, he directed a team of measurement and evaluation specialists at New Philanthropy Capital, a research organization and consultancy in London that advises nonprofits on how to maximize the impact of their work. He led the team that won the Social Impact Analyst Association's 2014 Challenge on how to create a social impact report.
