“As a philanthropist constantly grappling with how I can achieve more impact, I found Jonker and Meehan’s insights to be provocative and engaging. They go beyond the typical rhetoric regarding ‘what the nonprofit sector can learn from business’ and give these organizations their due—with great advice. Nonprofits are dealing with often intractable societal problems of enormous complexity and uncertain revenue streams. These authors appreciate the weight on leaders’ shoulders, while offering a detailed roadmap to maximize their impact. A must-read.”
