Richard Client

Boot Barn incorporated the ALIVE active shooter survival training into the onboarding for all employees in 2023. We chose ALIVE for its dynamic and potent nature. It inspires a conviction for survival with practical methods. We want our employees to have the confidence to take lifesaving actions should they experience a mass shooting in the workplace or anywhere else. ALIVE has given us the edge we were looking for.
