Bob Einhorn's contributions to ONN have been deeply valued from the very beginning. He joined at a formative moment, when Laura Rockwood was shaping the Engagement Network and when ONN’s mission and methods were evolving. His experience, judgment and calm strategic perspective have been important to the organisation’s development, and I have always appreciated the thoughtful way he approached our discussions. On behalf of ONN, I thank Bob for his service, his insight and his collegiality. He will always be part of ONN’s history, and he will remain a valued friend of the organisation.
