KATY, TX — In the annals of Texas high school football, few coaches have left a mark as indelible as Mike Johnston. The visionary leader who turned the Katy Tigers from perennial underachievers into a state powerhouse passed away on January 10, 2026, at age 79. His legacy endures not just in the five state titles Katy has won since his arrival, but in the timeless principles of discipline, preparation, and teamwork he instilled—principles that continue to inspire programs across the Lone Star State, from the Houston suburbs to the wide-open fields of West Texas.
