John Hiester is a social impact leader dedicated to expanding opportunity and strengthening the organizations and teams that make it possible. In 20+ years working in the nonprofit and public sectors, he has helped teams and communities navigate growth, change, and impact across youth development, workforce development, educational access, and human services. His leadership is guided by a belief that lasting change happens when people feel seen, supported, and empowered to do their best work together.

Prior to GreenLight, he was Executive Director of Breakthrough Silicon Valley, where he guided the organization through growth, setting strategy and vision, and building a purpose-aligned coalition to support first-generation college students on their path to and through college. Earlier, he worked with Year Up Bay Area as Silicon Valley Site Director and Director of Operations and Strategic Planning, helping the organization manage change and scale its model to serve more young adults seeking economic mobility. He has been working in support of communities in San José for the past 15 years.
John holds a Bachelor’s degree in Spanish from Kenyon College and an MBA from the Boston University Questrom School of Management.
