David Brenner

Founding Principal & Lead Designer

Working at the intersection of botany, architecture, interior design and urbanism, 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 from California Polytechnic University at San Luis Obispo. He credits his time spent studying at the Royal Botanic Gardens in Kew, London, with setting him on the path to living wall design. It was at Kew that he came to appreciate the beauty of epiphytic plants – those which have naturally evolved to grow vertically on trees.

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, designing 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.
