A Message from the Principal of John Horn High School
At John Horn High School, we believe in the power of potential, the strength of community, and the promise of every student’s future. Whether you are a returning Jaguar or new to our campus, you are an important part of a vibrant school family where excellence is the standard and growth is the goal.
Our staff is committed to the values that define who we are as Jaguars:
ROLE: We believe every Jaguar has unique talents and abilities, and everyone belongs here.
RESPONSIBILITY: We take initiative, hold ourselves accountable, and protect the family.
RELATIONSHIPS: Our bonds run deep—we invest in building strong, meaningful connections.
RESPECT: We always show respect to our school, each other, and our community.
As principal, I am honored to serve our students, families, and the Mesquite ISD community. I look forward to a school year filled with achievement, celebration, and meaningful connections. Let’s make it a great year—together.
With Jaguar pride,
Deeadra Brown
