Dave Leff

Dave Leff is the founder, president and CEO of LEFF Construction Design Build, which is celebrating 40 years of serving Sonoma County homeowners. Leff was born in London, where he lived until moving to San Francisco at the age of 9 years old.  He attended Sonoma State University, graduating with degrees in Psychology and English. Leff was on his way to law school when he decided to stay a little longer in Sebastopol, California, to improve his carpentry skills. In 1978, Leff formed LEFF Construction as a sole proprietor, and was joined by his father in 1987 when they incorporated the company.

Leff is a Certified Green Builder, and over the decades has become an expert in solar and sustainable building, historical renovation and infill real estate development. He’s dedicated to alternative building approaches, and his passion for building and remodeling homes that are beautiful and functional—and that integrate sustainable principles with new technologies—has informed his company vision and the development of his design/build approach to all projects.

Leff has been an instructor of the remodeling process to homeowners and contractors. He and the LEFF team hold remodeling workshops for homeowners at the new LEFF Design Center several times a year. He serves on the Board of Directors and heads up the Green Building Committee of the North Coast Builders Exchange, and he participates as a speaker and panelist in conferences and events about sustainable building practices.
