Profile

Guillermo Castilleja leads and oversees strategy for the Gordon and Betty Moore Foundation’s Environmental Conservation Program, which seeks to protect critical ecosystems and balance long-term conservation with sustainable use. The program includes an interlinked trio of market-based approaches to conservation (the Conservation and Financial Markets Initiative, Forests and Agricultural Markets Initiative, and Oceans and Seafood Markets Initiative) as well as initiatives that focus on the Andes-Amazon, Marine Conservation and Wild Salmon Ecosystems. 

Before joining the foundation in 2010, Guillermo worked for World Wildlife Fund-International (WWF), most recently as Executive Director for conservation. In that capacity, he directed and coordinated its global conservation efforts, leading the development of global priorities for the network, overseeing implementation of its activities and monitoring progress. He has also worked for the World Bank and the National Wildlife Federation. 

Guillermo graduated from the National University of Mexico and received a Master’s degree in Forestry, a Master’s degree in Philosophy and a doctorate in Forest Ecology from Yale University.
