A group of committed Catholic parents and then-Bishop of Yakima, Cardinal Francis George, worked to found the high school.

[5] Students at Lasallian schools gather regularly for prayer and Mass (liturgy of Catholicism), and are encouraged to participate in campus ministry activities.

Four service "immersion trips" are offered annually, which expand service-giving opportunities and provide social justice issues education to students.

La Salle activities offered throughout the year include Dances, Homecoming, Prom, weekly video announcements, lunchtime intramurals, and rallies.

The forty acre campus includes a soccer, baseball, fastpitch, practice football field and large gymnasium, as well as a number of tennis courts and a weight lifting facility.

On far end of campus near the Ahtanum Creek, La Salle has built a full service fish hatchery in cooperation with the Yakama Nation.

The hatchery is completely managed by La Salle students and teachers and is helping to re-establish important salmon runs on this area of the watershed.

Nearby the hatchery students operate beehives that produce Lightning Honey each year and serve as a resource for scientific study.
