Principal's Message

Dear La Salle Community,

Our Lancer Pride is evident from the moment you step on campus. From our rigorous academic offerings to our liturgical celebrations, our diverse population of students, our championship athletic teams, the creativity of our arts programs, and our Student Life experience, it is easy to see why many of us call this place home.

Here at La Salle, we are not just an educational institution. We are a community of learners bound by the Lasallian Core Principles that guide our every endeavor. Our commitment to the Lasallian mission is unwavering, and it is this mission that serves as the compass for our collective journey. As a community, we reflect daily on the Faith in the Presence of God, Respect for All Persons, Inclusive Community, Quality Education, and Concern for the Poor and Social Justice.

As we embrace these principles, I invite you to join us in fostering an environment where our students can thrive, where their hearts, minds, and spirits are nurtured, and where they are inspired to be the change-makers of tomorrow. Together we are more than just a school; we are a transformative force in the lives of our students and the wider community.

As a graduate of Catholic schools and a parent of Catholic school graduates, I’m very much aware of the value of a faith-based education. Our faculty and staff are committed to the tenets of our namesake, St. John Baptist de La Salle, who regarded a school as a community of believers working cooperatively to achieve a shared vision. We look forward to promoting that vision with our entire Lasallian community: past, present and future.

Please feel free to reach out and say hello.
