About me
Stephanie S. Jarvis, BSc, MSc, WE-9457A, PNW CTRA-1563 has been farming truffles and medicinal fungi in California for nearly 15 years. She holds an MSc in Ecology, Evolution, and Conservation Biology (mycology focus) from San Francisco State University, where she completed a monograph on the Lycoperdaceae (puffball fungi) of California, and a BSc double major in Plant Physiology and Organic Chemistry from Sonoma State University, where she worked on the Sudden Oak Death research team.
A Certified Arborist and Certified Tree Risk Assessor since 2010, Stephanie developed a CEU-accredited training for the ISA Western Chapter focused on fungal pathogens and assessing trees at risk of failure due to decay.
Her applied cultivation background includes an internship at Aloha Medicinals (Carson City, Nevada) and professional training with Paul Stamets at Fungi Perfecti (Olympia, Washington). More recently, she spent two years leading Mycology Research & Development at a leading functional mushroom farm. Today, Stephanie works as a Value Architect—helping mushroom-centric companies map value, strengthen partnerships, and build scalable workflows that support sustainable growth.
Stephanie founded Pacific Truffle Growers (PTG) to support truffle orchard planning and rehabilitation through soil and root assessment, host tree health strategies, and truffle-focused management. She manages truffle orchards across the West Coast and beyond, consulting with growers and landowners throughout the U.S.
Stephanie serves on the Board of the Sonoma County Mycological Association and the North American Truffle Growers Association, and is a member of the Functional Mushroom Council. As a teacher, she brings warmth, precision, and a builder’s mentality—offering tools audiences can use, from foragers to growers to formulators, where the science stays accurate and the magic stays intact.
