Ghilotti Bros., Inc.

If you have lived or worked in the Bay Area in the last 100 years, you probably have heard of the success story of James Ghilotti, the Italian immigrant, who coming to San Rafael in 1910, started a small construction company in 1914.

The fruits of his labor, Ghilotti Bros., Inc. employs more than 225 individuals working in 11 Bay Area counties and generating annual revenues in excess of $100 million per year.

Along the way, GBI has contributed not only monetarily but with our time and resources to several hundred organizations in our community. To further enhance this effort, GBI employees established the GBI Giving Back Program in 2009. These efforts following the footsteps of our founder James Ghilotti’s philosophy, “Earn respect by doing a job well, treat employees with courtesy and respect, and do good work for the community in which you live and work. “

GBI is proud to be entering a new era with our 4th generation, Mario Ghilotti joining the firm as a Project Manager.

We continue to support our founder’s philosophy to do quality work, treat employees with respect and give back to where we live and work.

While celebrating our 105th year of business, we reflect on the good fortune of living and working in the most beautiful place on Earth and appreciate the legacy of doing quality construction in Marin. We believe it is our privilege and our responsibility to help others in our community and it’s why we are so excited to be a partner in the “Giving Marin” program, where in each month GBI will support two to three deserving non-profit organizations by sponsoring their outreach in the Marin IJ and on
