Our Team

The Greenleaf team brings a variety of backgrounds and perspectives to our work– we believe this enables us to engage more effectively with our collaborators to integrate disciplines and apply their research towards tangible results. A shared passion for supporting a sustainable, healthy world by addressing environmental causes of preventable human ailments is what brings us together and keeps us moving forward.

Our ability to effectively further our mission comes from the depth and variety of knowledge and expertise brought to programmatic work by our board of directors and service partners. We collaborate with the staff, service partners, and board at our affiliated organization, Greenleaf Advisors. They include leading researchers in the fields of human health, resource management, environmental sciences, economics, and other disciplines. Greenleaf staff provides the operational support and research project management to guide our service partners working together across disciplines to address primary environmental threats to human health. In this way, Greenleaf produces sound scientific recommendations to inform policies and practices.
