In 1993 Jeff Phillips started Trinity Builders to build and remodel homes with two focuses: the client and building high quality homes without the extra management that drives costs up. Trinity has grown into one of the premier family owned construction companies in Marin. Today Jeff and his son Sean guide their clients through each project. Clients have direct contact with the principals. Our quality craftsmanship, attention to detail, innovative thinking, open communication, and close relationships with clients set us apart.
