Trinity Church was founded in 1867, with a clear sense of mission and ministry to the community of Santa Barbara. The current church building was constructed between 1912 and 1919, based on plans developed by Philip H. Frohman, noted supervising architect for the National Cathedral in Washington, D.C.

The solemn beauty of Trinity Episcopal Church has provided solace and consolation to people in grief, in trouble, and in transition. It is also a place of celebration, and thanksgiving for life's many blessings and sacraments, including Eucharist, Baptism, Matrimony, Confirmations, and other rites. Trinity is a place where parishioners, community members, and others on The Way can turn to worship, pray, reflect, and find hospitality.
