Suraya grew up close to nature in Hawaii and moved to California to start college when she was 17 years old. She has degrees in Agricultural Business from Feather River College and Sustainable Agriculture from University of California, Santa Cruz. She found her love of nature through watching sunrises on the beaches of Hawaii with her mom, riding horses through forests and beaches, growing her own food, and exploring the redwoods. It is a passion of hers to teach the importance of environmental and food justice through farming. She is excited to continue her journey at Ecology Action.

Laurie spent most of her career working at various botanical gardens immersed in the fields of horticulture and botany with an emphasis on plant identification, classification and conservation. Organic gardening has been a personal interest since college and more recently she discovered the importance of gardening with heirloom varieties with a particular interest in growing heirloom tomatoes.

Dan Miller, Building Site Operations and Maintenance
Dan works part-time for Ecology Action in charge of building and site operations and maintenance. He is Ecology Action’s go-to person for anything requiring a creative solution. His responsibilities include taking care of the grounds; repairing fences, buildings, solar systems, generators and pumps; painting, fixing and oiling squeaky things; as well as being the resident expert in FileMaker Pro and taking care of the computers, printer, networking and satellite dish issues. He joined the ranks of small-town living after a career as sound engineer in San Francisco, doing sound for concerts, and as one of the founding organizers of the Burning Man Festival.

David Troxell, Communications Director
For as long as he can remember, plants have played a role of sacred importance in David’s life.  He spent his childhood growing redwood saplings and saguaro cacti in his family’s backyard in Southern California, then worked as a horticulturist and arborist for many years in Florida, before moving back to California to homestead with his wife, growing vegetables and managing the forest around their home. Although our current system rewards certain professions over those that work with the soil, David envisions a time coming soon when there will be no more valuable skill than the knowledge of how to grow one’s own food and medicine for oneself. Knowledge of plants, their culture, and their usage, is real power.

Janét has always been drawn to nature and to growing. Growing up north of Seattle, she ran a small organic market farm with her mom for a time. She studied Soil Science and worked for the NRCS after college for several years mapping soil. Before joining EA in 2022, she lived in Coos Bay, OR working voluntarily on environmental issues that impact the area, namely timber, including conducting citizen science surveys. For many years Janét was the organic produce manager of the co-op there, working with local growers. During the last few years she also owned and operated a small nursery. Janét has recently been acquiring soil microscopy skills and knowledge of the soil food web. She is very happy to be able to work with EA and learn the highly productive resource-conserving GB methods in-depth to help create a better world!

Jake Ellsworth Farmer/Teacher/Trainer I recently graduated from the University of Wisconsin Milwaukee with a degree in Architecture. I moved out to California as soon as I graduated in order to learn hands on the best methods of sustainable agriculture which I also studied in college for a year. I have a permaculture certification from Midwest Permaculture. I'm interested in empowering communities through sustainable local agriculture. I believe it is incredibly important to have a close relationship with our food and communities in order to repair the social fabric and natural environment of our country.
