John Leary
Executive Director

After 10 years of working and volunteering for Trees for the Future, John became Executive Director in 2013. John has deep knowledge of international agricultural development and extensive experience living with and among the rural poor in Sub-Saharan Africa. He speaks three languages well (and another three languages not so well) and has lived and worked in 12 developing countries. John has dedicated his life to creating innovative training approaches that empower farmers to rise out of poverty, and he has created award winning high-tech, low-tech, and no-tech training programs that are currently in use throughout the developing world. He is now focused at helping Trees for the Future end hunger and extreme poverty for a million people.

Ashleigh Burgess
Partnerships and Strategic Outreach

Ashleigh came to TREES by way of serving as an Agroforestry Peace Corps Volunteer in Senegal, where she lived in a rural Serrer village and worked with the host community to plant trees and work on a variety of community development initiatives. Previously, she lived in Northern France as an English teacher and worked for the Sierra Club as a legislative affairs intern. She is a graduate of Michigan State University (Go Green!) and studied International Development from the Department of Community Sustainability there (Masters of Science). When she is not talking about TREES’ powerful work and exploring new opportunities and partnerships for the organization, she is all about being outdoors, gardening, speaking French, practicing her yoga moves, and looking for Michigan microbrews in DC.

Gabriel Buttram
Director of Programs

Gabe’s development career began as a Peace Corps Volunteer with an engineering background. He was placed in a village in Lesotho to work in a vocational school but there wasn’t one there. There were no trees either, so he rooted into agroforestry and sustainable agriculture instead, and never looked back. Following Peace Corps, he received a master’s degrees in International Affairs from American University and in Natural Resource Management and Sustainable Development from the UN University for Peace. He now has over ten years of experience managing projects in Africa, Asia, and Latin America, and living and working with small-holder farmers, mainly in Africa. A guy named Muir said that “the clearest way into the Universe is through a forest wilderness.” Gabe agrees with this wholeheartedly and is most at peace when surrounded by trees.

Matthew Eide
Marketing & Communications Associate

Matthew earned his BFA in graphic design from The Art Institute of Seattle. Since then, he has worked in a wide variety of fields—from professional sports teams, to public relations, to international development. A native of Minnesota, Matthew is happiest while outside (preferably near a lake), watching soccer, or planning a road trip across Central Asia.

Corrie Mauldin
East Africa Regional Director

Corrie has years of experience working for both environmental NGOs and the Department of Interior while living in Washington DC. She lived for a couple of years in a remote forest village working with smallholder farmers in Cameroon, helped manage a CSA (community-supported agriculture) organic farm in the Northeast and monitored fish catch on vessels in the Bering Sea. As East Africa Regional Director, Corrie oversees a 16-person staff of Country Coordinators and Project Technicians throughout Kenya, Uganda and Tanzania.

Curtis McCoy
Deputy Director, West Africa Programs

Hailing from the suburbs of Chicago, Curtis studied Biology and Environmental Studies at Grinnell College. He began pursuing his passion for trees when he joined the Peace Corps as an Agroforestry Volunteer in Senegal, West Africa. Staying for more than 3 years, he split time between planting trees with local farmers and training new Peace Corps Volunteers. World travel is one of his passions; despite never tasting foreign soil until living in West Africa (he doesn’t eat dirt anymore though). When not planting trees, Curtis enjoys photography and spending his free time outdoors – biking, hiking, and camping.

Adaobi Okafor
Deputy Director of Finance & Administration

Adaobi moved to the U.S. from Nigeria to pursue her education at Georgetown University. She fell in love with D.C. and its blend of cultures so she stayed to complete her Masters at Catholic University of America and start her career. She is passionate about helping nonprofits maximize their potential by maintaining a healthy financial outlook. When not analyzing spreadsheets and chasing down expense reports, Adaobi loves travelling and experimenting with recipes.

Michael Popp
Global Business Development Manager

Spending the majority of his adult life outside of the United States, Michael identifies with the global citizen.  He developed cross-cultural understanding from trips to places like Senegal and a professional level of international business development through entrepreneurial adventures in China. Combining these assets with a personal passion for social enterprise makes him well suited to manage our corporate partnerships!

Daniel Schall
Business Development Associate

Daniel is a Maryland native who’s lived in Switzerland, Senegal and Guinea Conakry. He has a Masters in Geography and Environmental Systems and has spent more than five years working in environmental development. Aside from his penchant for wanderlust he also enjoys supporting the Washington Wizards and Baltimore Orioles!

Kendall Swenson

After finishing graduate school, Kendall joined the marketing and communications team at TREES. She is thrilled to help us make an impact on our projects by telling the world about what we do. She’s lived in Italy and loves living in the district, but her roots lie in Mississippi where she can’t get enough of, you guessed it, the sweat tea and cornbread.  Outside of the office, you can find her hiking with her pup, at a Nationals game, hanging with her 7 siblings, and traveling.

Andrew Zacharias
Director of Monitoring and Evaluation

Andrew grew up in a small farming community in central Ohio. After studying Political Science at Miami University, he moved to Tanzania to volunteer with the Peace Corps. His professional and cultural expertise allowed him to then work for Trees for the Future, managing agroforestry programs across East Africa. Today, he uses his knowledge of data collection and geographic information systems to direct the department of Monitoring and Evaluation. He lives in Columbus, OH with his wife, Mary.
