LA Johnny is a landscape architecture and consulting arborist firm specializing in trees. My “tree” practice draws on my experience across multiple disciplines: landscape architect, consulting arborist, construction manager, senior estimator and technical writer. You can’t just plant an urban forest, you have to engineer it. I help owners create beautiful trees and healthy urban forests.

Landscapes and urban forests are human habitats, subject to the same trade-offs and rules as natural habitats. It is a timeless principal – designing with nature. Trees are the charismatic mega-flora of these unique human habitats. I help owners and designers pick the best trees to save and the right trees to plant. I help them promote tree health and manage tree risks.

Many trees in southern California are protected by local laws. I help owners and designers understand the laws and make informed decisions. I prepare the various documents and plans needed to comply with these laws.

My services fall into the following six categories. If you need a landscape architect or consulting arborist, contact me to see how we can work together!
