School Leadership

Dear Friends,

Since 1966 Justin-Siena High School has provided a unique, college preparatory experience to our students and families from Napa, Solano, and Sonoma Counties. At the heart of our educational mission is a deep sense of community, centered on the message of Jesus Christ and animated through the tradition of the De La Salle Christian Brothers. This sense of community, along with a commitment to quality education, is the hallmark a Lasallian education, a mission shared by more than fifty-six Catholic high schools across the United States, and thriving in eighty-four countries around the world. We encourage you to review our history, mission, philosophy, and what it means to be a Catholic school in the Lasallian tradition as you explore what Justin-Siena has to offer.

If you are a prospective parent or student, please enjoy exploring information on our unique programs, college matriculation information, our academic departments and curriculum, as well as the wide array of co-curricular programs that challenge our students and allow their best selves to emerge.

If you are a current Justin-Siena student, parent, grandparent, alum, or benefactor, you will find helpful information throughout the school year such as daily announcements and news, faculty and course information, and communication related to athletics, arts, alumni, and school-wide special events.

For many people, high school represents four of the most formative years of their lives. It is our honor to, in unity and association with the dedicated faculty and staff, serve the young people entrusted to our care. Together, in partnership with parents, we develop the spiritual, intellectual, and personal capacity of each student. For they enter to learn, and leave to serve. This is the gift of Catholic education in the Lasallian tradition. Come be a part of the Justin-Siena experience today!
