Meet the Mangiantini’s

Meet John and Jennifer Mangiantini, the proud owners of Mangiantini Home Design and Build. John was born in Sonoma, California, and has been a General Building Contractor for over 25 years. With Jennifer by his side, the two of them shifted their business model to now include planning and design services – creating a complete design and build solution for customers seeking new homes or renovations.

Read Full Bio

Jennifer’s 25+ years as a Business Consultant helped put strong business practices in place which was instrumental in growing the business into one of the top Design-Build Construction companies in Sonoma County.

John’s unwavering commitment to his craft comes from his earlier years living and working in the community. John’s experience as a Supervisor at the Valley of the Moon Water District and overhauling submarines at Mare Island taught him precision and attention to detail – skills that are utilized in all building projects today. After working on several home projects, he realized that construction could be an opportunity to build the dream of living and working in Sonoma for years to come.

John developed deep relationships with friends and families in his local Italian community who helped him gain exposure through word of mouth while building trust along the way. Soon enough, building and renovating in Sonoma was in demand, and Mangiantini Construction was born.

Sonoma has always been John’s hometown, full of beauty, family, and friends. Now it’s home to Jennifer as well. Looking back, there was never any consideration that they would leave it behind – For John and Jenifer there is no better place to be.

Motivated by living their own Sonoma dream, John and Jennifer love sharing the Sonoma culture by building their clients their own custom made dream homes – resulting in the Mangiantini you know today!
