Our Leadership Circle
Director of Programs & Partnerships
Leah joined MESA in 2004 and now serves as Collaborative Director. Her Humboldt farmland roots instilled a love for food and farming practices that nourish people and the planet. Leah moved to the Bay Area in 1999 to pursue degrees in Environmental Policy and Spanish at UC Berkeley. She has lived in South and Central America as well as Southeast Asia working on behalf of social, environmental and food justice initiatives. As a result of her travel and work experiences she gained insight into myriad traditional agricultural practices, implications of a globalized corporate food regime and the value of farmer-to-farmer knowledge exchange, agroecology and unconventional multi-interestholder collaboration. Her past work experience includes program development for the International Institute for Bengal Basin which focused on pollution mitigation for farmers and rural communities in Bangladesh, fund development for the East Bay Sanctuary Covenant and supply chain review for Scientific Certifications Systems. Leah is a co-founder of Wild and Radish, LLC, and developing a 10-acre urban farm and eco-village in El Sobrante, CA. She currently serves on the Board of Directors of Planting Justice, an Oakland non-profit creating green jobs and democratizing access to affordable, nutritious food. Climbing rocks, yoga, milking goats and befriending bees are frequent sources of fascination.
Natalia Pinzón Jiménez
Director of Programs & Education
Since late 2013, Natalia has been a devoted to MESA’s network both online and on the ground. Now as Collaborative Director, she spearheads the development and management of MESA’s Social Learning Network for Social Change as well as the Certificate in Applied Agroecology and the Climate Course for Farmers. Natalia supports MESA through grant writing and research design. In 2015, Natalia supported the fundraising and development for MESA’s beginning farmer training program, to support fellow immigrants in realizing viable farm business. Natalia immigrated to the US from Colombia at a young age. She comes from a lineage of software developers and agriculure enthusiasts. She’s blessed to be able to combine these two interests at MESA; where her respect for agroecology need not be held back. As secretary of the Latinamerican Scientific Society of Agroecology she frequently looks for ways to integrate agroecology research & education into MESA’s work. Natalia is currently working on her PhD at UC Davis in the Geography Graduate Group. Off hours Natalia can be found late-nite scheming with colleagues and friends or milking her goats at midnight.
Development & Strategy
Alexandra combines a passion for food sovereignty with a mind for organizational development in her role with MESA. First introduced to MESA when working side-by-side with Stewards at an organic farm in Long Island, she was intrigued by MESA’s education and engagement work and strong global network. Her own path has taken her across Latin America working with social justice issues in the region, to various farms and gardens where she learned about agroecology, and to a number of nonprofit organizations. Always drawn to social change work, she realized her best contribution could be through strengthening her organizational and management skills, and completed a Master’s in Public Affairs with a concentration in Nonprofit Management. To build her perspective on the history and context of this work, she also completed a Master’s in Latin American Studies with a focus on food policy and social movements in Latin America. With this basis, she launched into the food sovereignty movement in the Bay Area and now in Cusco, Peru. She looks forward to creating links in MESA’s global network and advancing the mission of the organization, in harmony with her own values and goals.
Founder, Director of Programs & Operations
With a career devoted to cultural exchange and experiential learning, Lauren served nine years as assistant director at a “conventional” agriculture exchange program before founding MESA. Inspired after speaking with an organic farmer, and alarmed by the increasing incidence of pesticide-related medical claims made by trainees in her old program, in 1994 Lauren founded MESA to promote sustainable farming alternatives throughout the world. Lauren’s Lithuanian grandmother’s wonderfully inventive cooking, coupled with a B.A. in Russian Language & Literature from the University of New Hampshire at Durham, sparked her initial interest to pursue a career in cross-cultural exchange focused on food and agriculture. In 1996 Lauren successfully negotiated the Kafka-esque designation process for MESA to become a J-1 Training and Cultural Exchange Program with the U.S. Department of State. Lauren served as Executive Director until 2013. Lauren now delightedly shares director duties under MESA’s newly minted shared directorship model.
Research & Education
Paul joined MESA in 2016 as the Co-lead Farm Educator for the Bay Area Farmer Training Program. In addition, Paul is a lecturer at UC Berkeley where he teaches a course called Community Engagement in Food Systems. Paul has been involved with organic farming & marketing, agroecology, and social movements for the past 15 years in CA and abroad (Brazil, Mexico, Mali, and Malawi in particular). As a Research Associate at Michigan State University, Paul studied the potential for perennial staple seed and pulse crops in smallholder farming systems of Mali and Malawi. His doctorate at UC Berkeley involved participatory research on climatic variability and rainfed agriculture with CEDICAM, a civil society organization in the Mixteca Alta of Oaxaca, Mexico that uses the farmer-to-farmer training methodology. Paul’s experience in organic farming & marketing comes from his membership in a Bay Area worker’s collective, as well as working for ALBA and several other organic farms.
Outreach & Engagement
Katie has worked for over a decade in the food movement as a researcher, writer, educator and beginning farmer. She ran an international, solidarity travel program for four years bringing people to the frontlines of the global Food Sovereignty movement, working with affiliated partners from La Via Campesina, The Basque Farmer’s Union and The Korean Women’s Peasant Association. After advocating for farmers internationally for many years, she decided it was time to get her hands dirty in local soil and completed the 6 month apprenticeship program at the University of California, Santa Cruz Center for Agroecology and Sustainable Food Systems, where she graduated with a Certificate in Ecological Horticulture. She also holds a B.A. in International Studies from the University of California, Santa Barbara which grounds her work in global systems and social justice.
When she is not at MESA, Katie farms at Singing Frogs Farm in Sebastopol, CA, growing food and sequestering carbon!
Agroecology Alumni Educator
Lauren developed an interest in food and agriculture during her time as a geography and political science major at Bucknell University. She later went on to get a graduate degree in geography from Penn State, where the focus of her research was agricultural supply chains and stakeholder decision-making for farm-to-school programs. She now feeds her passion for agriculture through participating in an Oakland community garden and serving on MESA’s board of directors. Lauren currently works as a Program Manager for Environmental Defense Fund’s Oil & Gas Program.
Mary Collins aka “Mary from Maryland” has worked with animals ranging from cattle to cheetahs. Working in wildlife conservation made her question its connection to sustainable agriculture, so she joined the Peace Corps to learn first-hand how people farm and eat. In Panama, she worked side-by-side with famers and families to implement sustainable agriculture techniques. She extended a third year to serve as Regional Coordinator, a role in which she served as a bridge between Peace Corps, local government agencies and communities. Currently she is getting a Master of Public Policy at University of California, Berkeley and plans to work with sustainable agriculture and environmental conservation.
Bill’s entire working life has had some connection to the family farm. Childhood chores on the farm progressed to adult responsibilities and eventually Bill managed the dairy and walnut operation for the family. Meanwhile he ran a photography studio in Gustine for 30 years and spent short stints with the US Postal Service and the local newspaper.
As the family phased out of “conventional” farming Bill began growing and selling vegetables from about 2 acres carved out of the original family farm. Using regenerative practices, Bill has cut outside inputs to a bare minimum while reducing pest and disease problems. Contented Acres Produce operates a semi-weekly farmstand, and runs a small CSA.
Bill has hosted five different MESA stewards from four countries with financial support from Gustine Rotary Club. Working with farm stewards has amplified Bill’s passion to support small farms feeding their local communities worldwide. MESA programs facilitate the commingling of the best of ancestral knowledge and modern sustainable technologies.
Soon Bill will have a somewhat different experience to share with MESA stewards. Bill and his wife, Marybeth have moved a century-old farmhouse onto a city lot. While the original garden at Contented Acres Produce will continue, Bill will also be growing produce in a large backyard garden within the city limits.
