Congregation Kol Shofar, Conservative synagogue in Tiburon, California, US.

Congregation Kol Shofar occupies a renovated former school building that houses a large community hall and a modern sanctuary space for services. The facility serves as a gathering place for regular prayer services, religious education, and family celebrations.

Founded in 1962, Kol Shofar met in borrowed spaces around Marin County for two decades. In 1984 the congregation acquired 215 Blackfield Drive in Tiburon, a site that had housed Reedland Woods Middle School from 1970 to 1976. A 2006 expansion bid drew opposition from the Tiburon Neighborhood Coalition over traffic and noise; the town council approved a reduced plan, and a 2008 court ruling let construction begin in April 2009.

The congregation's name, Kol Shofar, means "voice of the shofar," the ram's horn sounded on Rosh Hashanah and Yom Kippur. Its rabbis have been ordained at the Ziegler School of Rabbinic Studies, and Rabbi Paul Steinberg has led the congregation since 2017, following Rabbi Susan Leider (2012–2022) and Rabbi Chai Levy (2002–2018).

The synagogue stands at 215 Blackfield Drive in Tiburon. The town council's 2006 approval capped event hours, parking and the number of gatherings, so parking can be tight during services and events. Check the congregation's website or call ahead to confirm service and event times before visiting.

Before the congregation moved in, 215 Blackfield Drive housed Reedland Woods Middle School from 1970 to 1976. The 2009–2010 work cost $17.5 million and was designed by Herman Coliver Locus Architecture of San Francisco, adding an 8,300-square-foot social hall, four classrooms and extra parking.
