Our History: A Tradition of Excellence

In 1986, a small, home-based business opened its doors in West Marin. Michael and Bonnie Fontana had a clear vision for their new construction company – to provide an exceptional customer-focused team committed to professionalism, integrity, and a superior product.

30 years later, Fontana Construction has grown into one of the most respected construction companies in Marin County.

His respect and care for the client continue to create an environment that delivers great work on time. That's what sets Fontana Construction apart.
