About The President

Maria Czyz - President Of One Training

Maria Czyz began her career as an educator, working for the school district from which she graduated. She was inspired to give back to this community and to encourage disadvantaged youth, just as her teachers had done for her. Although safety was always a primary concern, when introduced to active assailant training, she quickly realized the realities of a deadly threat. Not only did she recognize that she was not equipped to deal with such a situation, but she also realized that the training could be improved. 
 
As an educator, she understood what it meant to be on the front lines daily. She wanted training for teachers by teachers. Maria Czyz left her teaching career to join Armoured ONE Training, where she quickly rose to become president. In her new role, she rebranded the company as ONE Training, working closely with school leaders—principals, superintendents, directors of facilities, transportation, and security, as well as teachers— to ensure that their training programs are tailored to every employee in a school district. 
 
Under Maria’s leadership, the training has expanded by over 200%, focusing on empowering educators with practical, non- intimidating strategies. The effectiveness of her approach was proven when one of their schools faced an attack, and thanks to the training provided by ONE Training and the security measures implemented by Armoured ONE, no one was injured or killed. The school district credited their survival to the comprehensive safety protocols Maria and her team had implemented.
About The Founder

Tom Czyz - Founder Of One Training

On December 14, 2012, 20 first graders and 6 adults were tragically murdered at Sandy Hook Elementary. As a father, husband, active shooter expert, SWAT operator, and homicide detective, Tom Czyz realized he couldn’t protect his own family.

Determined to safeguard America’s schools, he founded Armoured ONE and ONE Training with the mission to end the threat of active shooters.

The active assailant training for school staff provided by these organizations is meticulously crafted, recognizing that over 80% of the time, the shooter is a student or former student. The training offers options-based strategies that exceed the federal guidelines of “Run, Hide, Fight,” by incorporating the enhanced strategy of “Barricade.” This approach is grounded in data and analytics from over 50 years of school shootings, enabling the provision of the most effective strategies to maximize safety and save lives during these critical incidents.

Tom is nationally and internationally recognized for his expertise in active shooter scenarios, school security, and motivational speaking, featured by major media outlets. He is also the author of “Staying One Step Ahead: Ending the Story of Active Shooter in America’s Schools,” published by Forbes Books.

Additionally, Tom has assembled top experts from SWAT, military special forces, federal agencies, and school staff to save lives. Since then, his team has responded to over sixty K-12 school shootings, including Sandy Hook, Parkland, Santa Fe, Uvalde, Newport News, and Nashville.

How Our Training Saved Lives During An Attack In 2015

In 2015, a former student carried out an attack at one of the schools we had provided training for. However, due to the physical security enhancements and the staff's swift implementation of their training, no lives were lost, and no innocent individuals were injured. The assailant roamed the premises for approximately 8 minutes before law enforcement arrived and apprehended him at gunpoint. Promptly responding by initiating a lockdown and following the Run, Hide, Barricade, Fight protocol as taught, the staff demonstrated preparedness, ensuring the attacker could not reach any victims. This incident vividly underscored the effectiveness and significance of our training program.
