- 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

“I have engaged David as a consultant to our policy program administration team at the Aspen Institute as part of our program review process. David worked with directors of three disparate Institute programs to understand their learning questions and develop thoughtful, sometimes individualized interview protocols. He interviewed Members of Congress, prominent legal scholars, fellow evaluators, and foundation program officers. His summary reports contributed to the internal review process and helped strengthen the programs' strategies and tactics. He is thorough, conscientious, and an easygoing partner in what can be challenging and potentially tense review processes.”

“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.”
