Brian Pedersen
Co-Founder | Operations & Strategy
Brian Pedersen brings a multidisciplinary background spanning horticulture, engineered systems, and the creative arts. His path into agriculture was not linear. He began his professional life in audio engineering before discovering, somewhat unexpectedly, that working with plants offered the same blend of precision, rhythm, and creative problem-solving that first drew him to music.
Over time, that interest became a vocation. Brian has led large-scale agricultural development projects across a wide range of environments, including advanced hydroponic production facilities, urban high-rise farms, correctional institutions, and projects in the Caribbean. His work has focused on program leadership, infrastructure design, and building production systems that translate ambitious ideas into reliable, day-to-day operations.
He is drawn to agriculture because it bridges science and stewardship, pairing technical rigor with meaningful, tangible impact.
At West Marin Landscape Nursery, Brian oversees production planning, infrastructure development, and long-term strategy, helping build a resilient operation that supports both professional contractors and home gardeners throughout the region.
