Why ONE Training LLC? 

Active Shooter Attack Investigation

ONE Training LLC travels to the scenes of  shootings across the nation to obtain valuable information which can be used to help thwart future attacks. Our training evolves as incidents do. We carefully study each shooting scenario to build on our knowledge of active shooter attacks, and keep our training relevant and effective. Our investigators report their findings to our training staff who in turn apply them to our training methods and lifesaving solutions. 

The right training for the right people

We focus on providing the appropriate training to the correct staff member in accordance with their role. Every role in your organization has its own unique set of vulnerabilities that must be met with bespoke safety solutions. For this reason, ONE Training LLC offers customized programs that tailor the training to specific roles. ONE Training LLC covers it all; from support staff to executive leadership, we ensure comprehensive preparedness at every level. 

Provide Counseling and Resources to Survivors

Our company Chaplain Josh Czyz is part of our investigative traveling team and is on site to counsel survivors and loved ones who are affected by the shooting. His Faith in God and his extensive training in Critical Incident Stress Management allow him to effectively offer comfort for those who are grieving from unimaginable loss.
