In every endeavor, we aim to cultivate growth of the mind, body, and spirit. Like our Founder, St. John Baptist de La Salle, we guide our students to become all God made them to be, and a strong partnership with parents is essential in achieving this goal.


A dedicated, competent, and caring faculty is at the heart of Justin-Siena. Inspired by the work of our Founder, St. John Baptist de La Salle, the Patron Saint of Teachers, our faculty and staff breathe life into our mission to provide educational excellence in a Christ-centered community.
