My mother's father was "a peasant" - he grew what he ate, bartered the food he grew for goods, and used his skills and knowledge to grow a living on a small parcel of land and bring his family forward. In contrast, I grew up in a city, and had lost touch with the traditions my grandfather knew so well. I wanted to regain that connection, and in 2000, I felt a strong need to begin cultivating the land - almost as though my grandfather was calling out to me. But I wanted to do it in a way that was friendly to and respectful of nature.

After attending several workshops and investigating different low-impact cultivation methods, I was lucky enough to discover the GROW BIOINTENSIVE method, and from there I had a clear idea of what I wanted to do. In the beginning, I was teaching myself and, thanks to the good soil of my farm, the results were amazing from the start.

Later I had the good fortune to meet Julio Cesar De La Garza and Juan Manuel Martinez Valdez, as well as other good biointensivistas across Mexico, who helped and supported my learning process and allowed me to delve deeper into sustainable Biointensive farming.

Here's a picture of me in my thriving garden!

Felicia HermosoFelicia Echeverria Hermoso - San Jose, Costa Rica
fecheverriahermoso [at]

First of all, I am a mother and grandmother and am concerned about the future of children. I am also in love with life.

I have worked for nearly 20 years in organic agriculture, including seven years in the Costa Rican Ministry of Agriculture and Animal Husbandry as Manager of the National Program for Organic Agriculture; the remaining 13 years were spent working in private initiatives and on my own projects. During all these years, I gained valuable experience and received training in many areas related to sustainable development, organic agriculture (with emphasis on GROW BIOINTENSIVE) and permaculture while working with various community-based organizations to generate policies and support programs. I also managed to develop a wide network of contacts and friends who work in these areas, both in Costa Rica and internationally.

In 2006, I bought the land that today is the El Casquillo farm. I have spent the last six years investing the savings I generated while working as a consultant to construct the infrastructure necessary to build this wonderful space, as well as living here while organizing networking and training activities. During the past year and a half I have been working on the recovery of the farm’s soils and on the development of the partnerships necessary to make a reality of my vision of a simple, abundant and happy life. My dream is to share the experience, expertise and contacts that I have accumulated with local communities, with volunteers and other stakeholders. I also dream of having a space where others can share their own knowledge, experiences and vision while enjoying and learning together.

Felicia is an enterprising person, optimistic and full of dreams. That's why she visualized, founded and directs the Cultura Verde project (find it online at


Mateo González López - Tepotzotlan, Estado de Mexico, Mexico Mateo Gonzales
: mgonzalez[at]

I am 32 years old, happily married to my wife Pryscila, and enjoying our baby girl of 10 months. I currently work at Xochitla Foundation A. C., a civil society organization located in Tepotzotlan, Mexico. The foundation's mission is to develop, consolidate and guarantee the permanence of an urban green area for public benefit and to encourage public participation in creating an area where humans can reunite with nature, in a way that we can all learn from and enjoy. I have been working as a field technician at the foundation for five years, and am responsible for the areas of production and information for maintaining green areas in Xochitla.

I graduated from EARTH University of Costa Rica in 2006, with a degree in agricultural engineering. In October 2008 I attended my first three-day GROW BIOINTENSIVE workshop. In April 2009 I was selected to attend the six-month internship training at Ecology Action.  During my internship, I learned about the philosophy and principles of Biointensive agriculture, reinforcing concepts that I could use for teaching the method through the Xochitla Foundation. On my return to Mexico, I began to establish a 500 m2 Biointensive orchard for teaching and training, research and production, with a capacity for 44 Biointensive growing beds.

This achievement through a conference “Primer Encuentro Latinoamericano de Biointensivistas” organized in May 2010 organized by Ecology Action, Cecadesu, Ecology and Population and Xochitla Foundation, the latter being host. This event marked the formal beginning of the activities of our Biointensive garden, which meant we had a responsibility to provide training courses to different groups, such as seniors (INAPAM), school groups, social, business and international instructors CECADESU scholarships from SEMARNAT. To date, we have educated a total of 1191 people; 32 courses have been given, with an average 37 people attending each course.

In 2011, I started training for basic-level teacher certification; I received my certificate in 2012 and am currently working toward certification at the intermediate level, which will allow me to train others as basic-level teachers.

Gustavo CamposGustavo H. Campos - Zapopan, Jal., Mexico
Email: gustavoh41[at]

I was born in june the 6th, 1941 in Guadalajara, Jalisco, México.

I graduated in 1966 as a Certified Public Accountant from the State Universidad de Guadalajara. I practiced accounting and finance for 34 years. Since my job was performed mainly in toxic environments, I was seriously ill since 1989, so I became semi-retired in 1991.

Christine Einung, an excellent homeopath, cured me by means of a diet based in vegetables, water, exercise and yoga. She strongly recommended that I begin producing my own food; unfortunately, I had not the slightest idea how to do so. Then, in 1993, while learning “How to draw with the right hemisphere” at Kimball College in Meriden Massachussets, I saw for the first time in my life at a truly marvelous garden. My generous hostess left a copy of “How to grow more vegetables” in my room, and I immediately felt in love with the method. I immediately set out to get a copy of my own, which I found in New York.

In 2004, I attended a 3-DAY GROW BIOINTENSIVE Workshop given by Ecology Action in Willits, CA.

Taking what I had learned, I developed many workshops in the northern and central states of México and the Sierra Madre in Jalisco, (Reserva de la Biósfera de Manantlán). I keep the records and photos for my personal satisfaction, and a certain feeling of happiness in my heart.

So far I am working in a 3 bed garden for my daughter Geo in addition to my own 6 beds.

I am in debt to my teachers John Jeavons, José Manuel Martinez, Marisol Tenorio and Agustín Medina.

Omar Garcia RamírezOmar Ramirez

Omar is a Mexican biologist and biointensive enthusiast, from a family of farmers. His parents came to settle in Tepotzotlán Estado de Mexico in the early 70's. As the fourth of five children, Omar attended basic studies of primary and secondary school next to his brother Alexander, in his beloved village of Tepotzotlán. He studied in the upper town where he was born, in Tlalnepantla de Baz, at the School of Advanced Studies at UNAM Iztacala, where he received a degree in biology, graduating in 2009 and joining work at the ecological park established by the Xochitla Foundation A. C., in Tepotzotlan, Mexico.

In Xochitla, Omar worked in the organic Biointensive nursery and demonstration garden since 2008. He got his start taking care of the Biointensive garden while his friend Mateo Gonzales (also a Biointensivista) attended a 6-month internship at Ecology Action. And the work paid off: in October 2011 Omar was able to attend the teacher certification workshop held in Patzcuaro Michoacán CREDES where he achieved Basic-Level Teacher Certification after one year.

At the end of 2012, Omar left Xochitla to start a new profession and formed the group Colectivo Centli Hombres de Maíz promoting organic farming through Biointensive farming and its benefits, and working with productive projects such as the local womans group growing Coyotepec dahlias, forming the group Esmeraldas en la Dalia.

Alma MolinaAlma Isabel Guzmán Molina

Born in Querétaro city, México, I grew up in the city but, because of my grandfather, I was always near to the countryside and I learned to love nature. I studied agronomy but I realized how bad the impact of industrialized agriculture is to the planet and therefore to life, and also realized how little awareness we have of this. After graduating, I start to learn and implement urban agriculture by making an edible garden at home and teaching family, neighbors and friends why it was important, and how to do it.  Then, I had the opportunity to have an entire field, and I began to grow corn, beans and zucchini in an organic way.

I have been always close to rural communities and to the most marginalized people of the State. I could see their reality and their needs, so I learned to use Biointensive methods, and started a program to promote this kind of agriculture with 2,500 families. Now, I am working in a civil movement called “El Maíz Más Pequeño” participating in a project to include sustainable agriculture in upper secondary-level education as a tool against climate change. I am also involved in other sustainable projects in the city with other groups, and am trying to make a transition to true sustainability in my own life.

Marisol Tenorio Lopez
Master-Level Certified GROW BIOINTENSIVE Teacher - Aguas Calientes, Ags., Mexico

Marisol has lived all her life in the city of Aguascalientes. She and her father volunteered in the NGO, Aguascalientes Ecological Conscience for 15 years. They organized recycling campaigns and pressured the state government for better policies on land use and environmental and water pollution. They also investigated a region where many people had kidney problems, which they suspected were due to conventional agricultural practices. This work led her towards a more sustainable agriculture. With a university degree in Biology, Marisol´s job is with the State Environmental Protection Agency. However, her real passion is for her volunteer work.

Jose Agustin Medina Macias
Advanced-Level Certified GROW BIOINTENSIVE Teacher - Aguas Calientes, Ags., Mexico

Agustin has also lived his whole life in Aguascalientes. However, he used to go into the countryside with his father, who worked as manager of a state natural reserve. He could see that life was simpler there and he also began to understand the people´s problems. He studied Agribusiness at the university, but didn´t agree with the Green Revolution. His emphasis was on Ecology and Rural Development, where he started learning about ecology issues. After university he took a six-month course from a Biointensive teacher and also started teaching Agustin and Marisol, Intermediate GROW BIOINTENSIVE teacherssustainable development on a volunteer basis.

Allan LaValierAllan LaValier
Stillwater, Minnesota  
email: firetrios [at] 

Allan attended two-Three Day Workshops with John Jeavons,one in Iowa and one in Wisconsin. In addition, he attended the 5 day Basic Level training in Willits with John Jeavons and Carol Cox. He presently maintains a plot at a local community garden and in his own back yard. He teaches gardening classes through River Market Co-op in Stillwater, MN. The community garden is located on a large tract of land two miles from Stillwater. Adjacent to the garden are two other small-scale farms. Allan is working with one of the farmers who grows heirloom dry beans for local restaurants. They will be exploring ways to commercially grow heirloom pole beans and peas including The Dutch Capucijners pole pea, Potawatomi pole lima bean from the Potowatomi Nation, and Good Mother Stallard pole bean.

Allan is presently painting homes and teaching for his family's income needs.  

Allan was asked to establish a garden for a family a few years ago, and, with the assistance of the owner's daughter removed sod and double-dug about 450 square feet. There were plenty of resources available to him to perform the ground preparation with a machine but then the opportunity to learn would have been lost. He was also the director of a small Montessori School in northern Minnesota. During his Montessori training in the 1980's, he was introduced to the book How to Grow More Vegetables… and found that young children are naturally drawn to nature and establishing relationships with plant and animal life. He found that children, when exposed to work in a garden, will often insist on having one established at their home.

GROWBIOINTENSIVE gardening, meditation, and spiritual growth are some of the most important experiences in his life.
