St. John Baptist de La Salle, Pray for Us

Welcome home, Mustangs.

Mullen High School has built a family of over 8,000 alumni who share in the love, pride, and tradition of our beloved school. Whether you are a former student, a parent of a Mustang or a friend of our school, we welcome you back and encourage you to engage with your alumni family.

The Alumni Office is honored to offer events throughout the year that will spark nostalgia, connect old friends and refresh your pride for Mullen. We loved having you walk our campus then, and we would love to have you back, if only for a short while. Browse our “Upcoming Events” tab to connect with us.

We are always eager to hear what our alumni have built on the strong foundation of their Mullen career. We want to celebrate your joys, grieve your losses, and strengthen our bonds by staying connected. Click on “Share Your News" tab to keep us informed.

Mullen High School has taken different forms throughout the years. Whether you lived at the boarding school, were fond of Brother Bernard or Sister Brendan, graduated in an all-boy class or raced onto the field in your beanie freshman year, one thing has stayed constant: our love and affection for Mullen High School. We would love for you to reconnect.

I’ll close with full faith that you can complete these words:

Live Jesus in our hearts…
