Justin-Siena High School

Justin-Siena is a Catholic high school in the Lasallian tradition called to provide educational excellence in a loving, Christ-centered community that prepares students to serve and to lead in an ever-changing world. Born of a collaboration between the Dominican Sisters of San Rafael and the De La Salle Christian Brothers, Justin-Siena has served families in Napa, Solano, and Sonoma Counties since 1966. Although firmly rooted in Napa, we are part of a Lasallian ministry that spans continents, centuries, and generations.
