Meet Louise Leff

Louise Leff has combined a lifelong love of the outdoors with her creative intuitions to design site sensitive gardens made to suit each individual client. Her formal education began at Merritt College, where she studied horticulture, and continued at the University of Oregon (Eugene, OR) and Rutgers University (New Brunswick, NJ) where she studied landscape architecture.

After receiving her degree in landscape architecture, Louise returned to Sonoma County to practice her talent for design on residential and public landscapes in Sonoma county, Marin county and Napacounty.
