Marcus Williams was formally sworn in as assistant chief of police for UT San Antonio’s Health Science Center April 7, marking a milestone in a career defined by strong leadership and operational excellence.
Williams brings more than 18 years of campus law enforcement experience to his role. Much of his career has been dedicated to public safety and police operations within a complex academic health environment, where he has cultivated a deep understanding of the specialized demands of campus and healthcare-based law enforcement.
Williams’ appointment as assistant chief follows 16 months of service as interim chief for UT Health San Antonio. In recognition of his exemplary leadership in this role, Williams was honored with the Executive Director Distinguished Command Award, presented by Michael Parks, executive director of police for The University of Texas System Police.
“[Assistant Chief Williams] stepped into the role of interim chief of police during a period marked by organizational change and operational complexity,” Parks wrote in his commendation. “Despite the challenges, [he] led with calm resolve, strategic clarity, and a focus on mission readiness.”
Officers at academic health centers are trained to operate in sensitive clinical and research settings, respond to high-risk medical emergencies, support patient safety and coordinate with inpatient and outpatient staff, first responders and administration, all while maintaining regulatory compliance and continuity of care.
