    What We Provide

    Our responsibilities extend far and wide. Beyond providing training to district staff in emergency management, we are dedicated to safeguarding the well-being of our stakeholders and assisting school administrators in bolstering safety across a broad spectrum of scenarios.  

    Our communication hub manages an impressive volume of over 30,000 service calls each school year, while also meticulously monitoring all radio communications between our command personnel and partol staff. 

    We place a significant emphasis on extensive training in collaboration with the Denver Police Department, preparing for a diverse range of situations. Thanks to our robust radio communication system, we maintain the ability to seamlessly connect with every police district in the city, as well as Denver dispatch. 

    Furthermore, we engage in fruitful partnerships with various jurisdictions across the metro area, collaborating closely with esteemed entities such as the U.S. Department of Homeland Security, the FBI, and the Secret Service to fortify our commitment to safety and security.
