Areas Of Operation

Ghilotti Bros., Inc. has operated in Marin County and the North Bay area counties since its beginning in San Rafael in 1914. As the company has grown and customers’ needs have increased over the decades, GBI has expanded into the East Bay and South Bay counties. GBI generally works within a 50-mile radius from the home office, but will go beyond those borders for attractive projects.

In 2006, GBI opened satellite regional offices in Cordelia (East Bay) and Rohnert Park (North Bay), in addition to the existing San Francisco (South Bay) office to reinforce their commitment to the areas where they work and better serve their clients. Currently, GBI’s span of influence includes 11 Bay Area Counties.
