Reginaldo (Regi) Haslett-Marroquin

Chief Strategy Officer for Main Street Project

Regi is the principal architect of the innovative poultry-centered regenerative agriculture model that is at the heart of Main Street Project’s work. As CSO, his focus is on the development of multi-level strategies for building regenerative food and agriculture systems that deliver social, economic and ecological benefits. He leads Main Street’s engineering and design work and currently oversees the implementation of restorative blueprints for communities in the US, Mexico, Guatemala and Honduras.

A native Guatemalan, Regi received his agronomy degree from the Central National School of Agriculture, studied at the Universidad de San Carlos in Guatemala and graduated from Augsburg College in Minneapolis with a major in international business administration and a minor in communications.

Regi began working on economic development projects with indigenous Guatemalan communities in 1988. He served as a consultant for the United Nations Development Program’s Bureau for Latin America and as an advisor to the World Council of Indigenous Peoples. He was a founding member of the Fair Trade Federation in 1994.

Regi served as Director of the Fair Trade Program for the Institute for Agriculture and Trade Policy from 1995 to 1998, and led the creation, strategic positioning, start-up and launch of Peace Coffee, a Minnesota-based fair-trade coffee company.

Regi currently lives in Northfield Minnesota with his wife Amy and their kids William (21), Ana Nicktae (17) and Lars Decarlo (12).
