Police Department

South Texas Independent School District established its own standalone district police department in the summer of 2025 through the hiring of its first-ever chief of police, Chief Steven Cortez. With the support of the STISD board of directors, Chief Cortez has worked alongside Dr. Marco Antonio Lara, Jr., STISD superintendent of schools, to expand this department to include a police captain and eight officers to oversee safety and security and law enforcement operations at the campuses on a day-to-day basis.
