Marney is a writer, teacher, farmer, and burgeoning podcaster for Critter Chat. Fulcrum Farm (Grass Valley, CA), now in its 22nd year, grew out of a love of food and nature. Marney, along with Lisa Bjorn, manage a comprehensive CSA that included dried goods, beef, turkey, fruit, and milk. Separate from the CSA they make Biodynamic compost for the nearby community, selling over 1,000 cubic yards annually. Before creating Fulcrum Farm, Marney started and managed a large-scale Biodynamic composting operation for the Presidio Trust, located in the National Park of the Presidio. The facility created compost for habitat restoration projects and provided a growing medium for all of the plants in the native plant nursery.

Lisa has spent her life in Nature. If she is not hiking, she is working outdoors. Once she found wood, she was enthralled by the feel of wood. Constructing all types of structures piqued her curiosity towards this amazing living medium.

Wood turning is like building, but instead exposing the empty space, the eternal space. “I Turn To Explore The Dark Inner Wood and Reveal the Inner Light of Trees.”

Before Lisa started turning wood, she was a Biodynamic farmer for over 24 years. Fulcrum Farm was a build from the ground up along with her partner Marney Blair.

Mac mentors Threefold Community Farm staff and interns. Mac began farming in 1975, when he had the “privilege and good fortune” to learn biodynamic methods directly from former co-workers of biodynamic pioneer Ehrenfried Pfeiffer at the Fellowship Community. In 2006, Mac became the Program Director of the Pfeiffer Center and is the core instructor of our Biodynamic Course.

Sea-Anna has been teaching eurythmy internationally since 2011, after graduating from the four-year eurythmy training at Eurythmy Spring Valley here in Chestnut Ridge, NY. She first encountered eurythmy through her work with biodynamic agriculture and has continually been inspired by the living relationship between biodynamics and eurythmy. Sea-Anna earned her MA in Performance Eurythmy from Alanus Hochschule (Germany), and is currently a member of the Eurythmy Spring Valley faculty and ensemble.

Jennifer teaches Speech Formation (Creative Speech) for the Steiner School of Speech Arts, the School of Eurythmy, Sunbridge Institute, and the Fiber Craft Studio. She directs community speech ensembles for local festival performances and performs with Eurythmy Spring Valley’s touring ensemble and in various local projects.
