Exclusively San Francisco, Trinity was founded in 1949 with a singular purpose—to become The City’s premier apartment provider. Seven decades later, Trinity stands “best-in-class” with apartments that offer the best locations, prices, and amenities.

We’ve remained The City’s most prominent provider of apartments, partly because Trinity is and will forever be family run. Founded by Angelo Sangiacomo, his late sister Rosetta and his wife Yvonne, the company has been sustained by two generations.

Think you’d be a great fit for Trinity? We’d love to have you join the team.   Check us out at trinitysf.com/careers
