What's in a name?
We serve more than 580 students from the Napa Valley as well as the neighboring Solano County and Sonoma Valley. We have a strong commitment to serve those who could not otherwise afford a quality Catholic secondary school experience with one third of our student body receiving tuition assistance. The school operates a small on-campus boarding program for both domestic and international students as well as an international host family program. We offer a college preparatory curriculum, a competitive interscholastic athletic program, a highly regarded performing arts department, and an array of co-curricular opportunities. The campus is comprised of 40 acres and situated in northwest corner of the city of Napa.
As a part of the Diocese of Santa Rosa, Justin-Siena is accredited by the Western Association of Schools and Colleges (WASC) and the Western Catholic Education Association (WCEA). Justin-Siena serves a variety of students from Napa, Sonoma, and Solano Counties.
In 1966 two schools opened on adjacent campuses--Justin High School (for boys) sponsored by the De La Salle Christian Brothers and Siena High School (for girls) sponsored by the Dominican Sisters of San Rafael. The schools merged in 1972 and were co-sponsored until the end of the 2005-06 school year when the Dominican Sisters transferred their sponsorship to the De La Salle Christian Brothers. Justin-Siena High School continues today as part of a world-wide network of almost a thousand Lasallian schools found in 84 countries.
The School is administered by a President and Principal and is staffed by a dedicated community of De La Salle Christian Brothers, Dominican Sisters of San Rafael, and lay men and women.
