- Amy Arbreton Evaluation Officer, William & Flora Hewlett Foundation

"During his term as part-time consulting program officer for the Hewlett Foundation, David effectively commissioned and managed a summative evaluation of the Foundation’s Nuclear Security Initiative. David’s management and leadership on this effort were stellar, contributing to the use of, and learning from, the findings in myriad ways for multiple audiences."


- Julia Coffman, Director, Center for Evaluation Innovation

“David Shorr has been a professional colleague of mine for at least a decade. Recently, as part of a larger evaluation project for the Corporation, David exhibited a professional, detailed, and well-honed understanding of both the nongovernmental and philanthropic arenas. He is enormously capable and dedicated to this field.”

- Patricia Nicholas  Program Officer,  Carnegie Corporation of NY

“We worked with David on an evaluation of a program to build bipartisan relationships and negotiation skills among senior staff on Capitol Hill. The evaluation was fast-tracked and on a deadline. David's high-level knowledge of the policy arena, excellent data collection and writing skills, and conscientiousness and professionalism ensured that the evaluation came in on time and delivered useful insights to the client. We look forward to working with David again.”

David Shorr is a strategic thinker and seasoned advocate who enjoys helping organizations that work in policy arenas such as Congress. David draws on extensive experience shaping debate and decisions in a variety of settings from high-level diplomacy and presidential politics to local land-use. Recent clients have asked David to: check the overall health of a major Washington think tank; gauge the performance of two grantees working to improve bipartisan cooperation in Congress; and conduct an 'evaluate the evaluators' review of one of the pioneers in the evaluation of advocacy and policy change. Most recently he evaluated Ford Foundation grantee TechCongress, looking at their first three classes of Congressional Innovation Fellows. Earlier in his career David served in senior roles with some of the policy community's leading philanthropies, think tanks, and advocacy groups: the William & Flora Hewlett Foundation, Stanley Foundation, Human Rights First, Refugees International, Search for Common Ground, British American Security Information Council, Arms Control Association, and Physicians for Social Responsibility.
