I have 2 daughters, one who just graduated from Justin, and the other is currently a senior. After touring many private high schools in the North Bay Area, I found that Justin seemed the most impressive with regard to its focus on the students path to college. Thanks to the excellent education my oldest daughter received, she received a full scholarship to an elite college in New York. The student/teacher ratio is excellent. The communication between the school and parents is top-notch. I couldn't have been happier with the education both my daughters received.

Justin Siena prepares students very well for college. The teachers are very friendly and highly invested in their respective subjects. The food is excellent, and I do not believe that anyone will find a better high school cafeteria. Sport games and other gatherings always make for a fun event. The arts department is excellent, and provides courses in a diverse range of areas. Overall, Justin Siena provides me with an excellent high school experience. Any student would be privileged to call themselves a brave.
