With over 25 years in construction, Brian Gannon has managed a wide range of projects, from building schools and high-end subdivisions to paving parking lots. He is licensed as both a general builder and an engineering contractor. 

In 1999 he left the world of large commercial projects to establish a smaller, more personal operation. Now, through Gannon Construction, Brian brings his expertise and exceptional customer service to Marin County home and business owners.   

A Marin resident for over 35 years, Brian earned a psychology degree from Dominican University before starting his construction career. He began by building houseboats in Sausalito and is still an acknowledged authority in leak detection and repair. In addition to technical skills, Brian attributes his firm’s success to thorough follow-up and communication as well as his reliable, courteous staff.
