Justin-Siena is a Lasallian Catholic college preparatory community that serves young men and women in grades 9–12. At Justin-Siena, students are nurtured and challenged to become the best version of themselves and truly realize their full potential. Our students learn and grow in an inclusive community of faith, representing a 300-plus-year Lasallian tradition of respect, welcome, and hospitality that makes it easy to "be you." Our students have different passions, gifts, personalities, and backgrounds. Our students have some things in common in their diversity: they love each other, and they love their school. They are ALL HEART. 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 the Napa Valley and beyond since 1966. Although firmly rooted in Napa, we are part of a Lasallian ministry that spans continents, centuries, and generations. We celebrate our Lasallian Catholic heritage as an independent college preparatory school. We serve as sisters and brothers to our students, celebrate God's holy presence, and commit ourselves to ensure access to those who seek this experience. To transform lives and communities is our vision. The Strategic Plan represents the culmination of many hearts, hands, and minds whom all brought forth their ALLHEART spirit to ensure that Justin-Siena boldly tackles a bright future.
