I've been a landscape designer for more than 25 years, specializing in using native plants, sustainable formats, and low-impact development on public and private sector projects. I design for commercial and mixed-use developments and for community spaces. Researching ecological and historical origins to provide cultural context, matching the right plant with the soil type, and choosing the most disease-resistant species are ideologies that I consider on every project. I develop tree assessment plans, urban forestry management plans, and city/county tree inventories.
I have a lot of experience with environmental resource permitting for activities relating to inland and coastal design, wildlife and vegetation surveys, and completing landscape designs for a diversity of projects. I've also enjoyed teaching university classes on biology, native biota, biodiversity, and sustainability.
