Building on trust Building an outstanding reputation for construction in the San Francisco Bay Area is a challenge fraught with pitfalls.

Nibbi Brothers General Contractors was established back in 1950 when Marino Nibbi, who at the time worked as a carpenter for another general contractor, decided to start his own construction company. Shortly thereafter, his brother Pete joined the business, as did his son Sergio in the late 1950s.
