Working at the intersection of horticulture, art and architecture, David has applied his passion for plants to a growing list of innovative projects, building a broad variety of modern, human-centric spaces with abundant plant life at their heart.
David is a pioneer in the field of vertical gardens. He holds a degree in Environmental Horticulture Sciences and Psychology from California Polytechnic University at San Luis Obispo. He credits his time spent apprenticing at the Royal Botanic Gardens in Kew, London, with setting him on the path to living wall design.

David sees his work as an integral part of a public shift in consciousness towards a renewed desire for closeness with nature and an appreciation of the restorative effect of plants, especially in urban environments. For David, creating living walls affords the chance not only to promote awareness of native and endangered plant species, but also to have a direct impact on quality of life.
David speaks on the benefit of living walls in urban architecture and his work has been featured in publications such as Fast Company, CBS, Wall StreetJournal, Dwell, Architectural Digest, The Los Angeles Times, Wired, Work Design Magazine, San Francisco Chronicle, andSan Francisco Magazine. In 2019 he was honored to join the 2019 Class of the “Top 40 Under 40” by The San Francisco Business Times.
