Trinity's congregation meets Sundays at the Novato Seventh-day Adventist Church at the corner of Simmons Lane and San Marin Drive. The Reverend W. Reid Hankins presides over a small but spirited group that will celebrate its 40th year in 2011. The church's denomination is the Orthodox Presbyterian Church, or OPC, which is confessionally reformed and conservative in its approach to theology. A men's prayer group meets at 9:45 a.m. Sundays and a children's Sunday School starts at 10 a.m. There are midweek prayer sessions, monthly community groups and Bible studies that take place in member's homes.
