Who We Are
In 1978 our Founder, Dave Leff, discovered a better way to build that aligns every voice surrounding a project—client, architect, engineer, interior designer, and builder—organizing a typically complicated process into a singular, holistic approach. This Design-Build philosophy—the first in Sonoma County—led to hundreds of better lives and happy homeowners. Today our history of crafting enduring homes carries on through the next generation of leaders at LEFF Design Build.
