GREENVILLE, Texas — Greenville ISD has approved the hiring of a new athletic director and head football coach, selecting a veteran South Texas coach with more than two decades of experience.
During a called board meeting on March 5, 2026, the Greenville ISD Board of Trustees approved the hiring of Christopher Castillo to lead the district’s athletic programs.
Castillo most recently served as defensive coordinator at Somerset High School (in Bexar County), where he helped guide the team to a 42–17 record over five seasons. Under his leadership, the program made four consecutive playoff appearances, winning three bi-district championships and one area championship.
Prior to that role, Castillo helped rebuild the football program at Mission High School, leading the team to three straight playoff appearances, a district championship, and its first playoff victory in six years.
In addition to football, Castillo has overseen successful boys and girls powerlifting programs, increasing participation and producing multiple regional and state qualifiers, as well as state champions.
District officials said Castillo brings experience in program development, staff mentorship, UIL compliance, and community engagement, with a focus on strengthening athletic programs and supporting student success.
“I am truly honored and incredibly excited to serve as the Athletic Director and Head Football Coach at Greenville ISD,” Castillo said. “I look forward to investing in our student-athletes, helping them grow on and off the field, and becoming an active part of the Greenville community.”
Castillo holds a bachelor’s degree in kinesiology from Cal Poly Humboldt and is certified in social studies and physical education by the Texas Education Agency.
He and his wife, Leora, have three children.
District officials said they look forward to Castillo’s leadership and the future of Greenville ISD athletics under his direction.
