As a high school teacher in Nevada, Lance Sargent understood the utter importance of securing classrooms from the threat of a hostile invader.

After participating in ALICE Training for active shooter situations, Lance decided to design a product which eliminated the potential for human error from securing interior school doors.

Upon its launch in 2016, the product was met with enthusiastic reception on both traditional and social media coverage. The Guardian Barrier team went on to secure consultation from the SCORE program and have since delivered Guardian Barriers to protect classrooms nationwide.
