Dear Future Mustangs,

Welcome to Mullen High School.  Thank you for your interest in learning more about becoming part of our Lasallian community.  Founded in 1931, in the tradition of St. John Baptist de La Salle and the Brothers of the Christian Schools, Mullen is a Catholic, college-prep high school whose graduates embrace God’s gift of learning, devote their lives to seeking ceaselessly for His learning, and commit themselves to using His learning in the service of others.  Mullen’s hallmarks are exemplary teaching, strong community of faith, rigorous academics, and the care and vigilance displayed for each student.

Centered in the three hundred year legacy of the Christian Brothers, Mullen is dedicated to the Five Core Principals of Lasallian Education:

  • Respect for all Persons
  • Participation within an Inclusive Community
