Armed Security Services in Orange County

Welcome to Treston Security Services

Premier provider of professional armed security solutions for schools, churches, hospitals, and other sensitive institutions throughout Orange County, CA. From private school campuses in Irvine and Newport Beach to houses of worship in Anaheim and Santa Ana, and medical centers in Mission Viejo and Orange, we understand that protecting vulnerable populations requires more than just a presence; it demands a strategic, client-first approach grounded in specialized training, deep sensitivity to the environment, and an unwavering commitment to safety.

That’s why we offer armed security officers specifically trained for educational, religious, and healthcare environments, along with security assessments, emergency response planning, and ongoing coordination with local law enforcement. Our team is built on a foundation of excellence, comprised of veterans with military and law enforcement backgrounds, as well as ASIS Certified Protection Professionals (CPP) and Business Continuity Certified experts. By leveraging real-time analytics and maintaining a steadfast commitment to transparency and accountability, Treston Security doesn’t just provide security—we provide absolute peace of mind for the institutions that matter most.

The presence of an armed officer at a school or house of worship must never feel militarized or intimidating to children, families, or congregants. Our approach emphasizes concealment, professionalism, and integration. Officers assigned to schools typically wear business casual attire or plain clothes with concealed weapons rather than tactical uniforms, and they focus on relationship-building with students, staff, and parents so they become a familiar, trusted presence rather than an alarming one. At churches, our officers coordinate with clergy and lay leadership to position themselves discreetly at entry points and during services without disrupting the spiritual atmosphere. We train our armed personnel extensively in de-escalation and verbal engagement, with the understanding that a weapon is a last resort, never a first response. The goal is to be prepared for the worst while ensuring the daily experience of students, worshippers, and patients remains welcoming and normal.

Healthcare security requires officers who understand the unique vulnerabilities of medical settings, including the presence of controlled substances, distressed patients and family members, and the need to protect both staff and patients during emergencies. For large hospital campuses, armed officers are typically deployed at entrances, emergency departments, and high-risk areas such as pharmacies and psychiatric units, where they serve as a visible deterrent and rapid response capability. For smaller specialty clinics, armed coverage may be more discreet, with officers stationed at reception or conducting periodic patrols rather than maintaining a constant fixed post. In all healthcare settings, our officers receive specialized training on HIPAA awareness, patient privacy, crisis intervention, and coordination with clinical staff during behavioral emergencies. We also work closely with hospital security directors and local law enforcement to ensure our protocols align with facility emergency operations plans.

Every armed officer we deploy holds a current California Guard Card and a valid firearms permit issued by the Bureau of Security and Investigative Services (BSIS), which requires completion of a firearms training course, psychological evaluation, and background check. Beyond the state minimum, our officers assigned to schools, churches, and hospitals complete additional training in active shooter response, threat assessment, de-escalation, crisis intervention, trauma-informed engagement, and emergency medical response. Many of our armed personnel bring prior military or law enforcement experience, and all officers receive ongoing training on legal updates, scenario-based response, and institution-specific protocols. We also conduct regular requalification and performance reviews to ensure every armed officer maintains the highest standard of readiness and professionalism. Before deployment, our team conducts a thorough security assessment of each facility and coordinates with leadership to customize post orders that reflect the specific needs and culture of the institution.
