His approach is grounded in systems thinking, equity, and practical field implementation.

The ecological, social, and economic crises of our time aren't three separate problems — they're one, seen from different vantage points. That thread has shaped over twenty years of Jessi Grillo's work across 30 countries, with farmers, communities, corporations, and governments. It runs through a career that includes leading climate-related livelihood risk modeling and disaster intelligence for USAID's Famine Early Warning System; integrated landscape and sustainable sourcing programs with the Rainforest Alliance; and co-designing a community-led carbon standard for Equitable Earth that channels finance directly to forest communities. She has advised more than 20 multinational companies — not just on what to commit to, but on how to make those commitments real across complex supply chains. Jessi specializes in translating technical and policy complexity into strategies that are both credible and equitable. 

Jessi holds a Master's Degree in International Development from Clark University, Department of Sustainability and Social Justice.
