Featured Seminar: COMMUNITY PREPAREDNESS AND How to Survive an Active Shooter Incident

Learn from the expert on how to identify the warning signs and the most effective ways to survive

The number of Active Shooter incidents occurring in the workplace, school grounds, and public spaces continue to increase. Communities throughout New York are recognizing that more training must be done to prevent and mitigate these tragedies. This seminar provides instruction in the tactics and techniques one needs to know in order to survive the the first few critical minutes of an incident. It also covers vital information on how to recognize a potential incident and prevent it from occurring in the workplace and in schools, as well as the importance of establishing “Safe Rooms”, taking other pro-active measures, and detailed instruction in the three areas you need to know to survive…Run – Hide – Fight.  This is our most popular seminar offered.

Hauppauge Public Library Theater

Our Active Shooter Training Has Been Showcased On:

Active Shooter Response Drills

Schools and workplaces tend to only teach “lock-in-place” methods in response to an active shooter incident. This technique only covers one aspect of surviving an active shooter incident and is not the most effective. It can create a “sitting duck” scenario if the shooter is already in the building.

Our active shooter seminars cover the more robust “run-hide-fight” technique, and we put them to practice in our active shooter drills. See below for an example of a real drill performed for a local library on Long Island:



Our Other Anti-Crime Seminars

International Travel Anti-Crime Techniques and Tactics
Anyone who travels abroad for business or pleasure should attend this seminar! In addition to the ever-increasing number of terrorist attacks occurring overseas, the number of criminal incidents involving violent crime against Americans has increased. These incidents include theft, robbery, assaults, larceny, kidnappings, car jackings, and abductions. These workshops teach how to become a “hard target” in order to deter criminals from attempting a crime, as well as safe and effective reactive defense techniques to be employed should an incident occur. This seminar is a variation of the workshop required of all U.S. government officials, employees, and their families prior to posting to an overseas assignment.
Everyday Anti-Crime Avoidance and Reactive Techniques--Lower Your Victim Profile
This is a basic anti-crime workshop on simple yet effective techniques to help you and your loved ones avoid being victims of violent crimes. Topics include: Embracing the Gift of Fear, Employing Situational Awareness, Becoming a Hard Target, and Safe and Effective Reactive Techniques. Workshop includes survival techniques and demonstrations of reactive and protective tactics.
Recognize Warning Signals in Children-The Real Story of Columbine High School
This seminar covers the series of events leading up to the tragic Columbine shootings and how it could have been prevented. There is also key information for parents, teachers, and education administration on recognizing warning signs in children and how to avoid these incidents. We offer the option to have this seminar presented in conjunction with our active shooter seminar.
Verbal Judo
Originally designed for police officers to enable them to defuse potentially violent situations, and to use language to gain compliance without resorting to physical force, this workshop is available to the public and is ideal for schools, churches, and security personnel, as well as for those in the business world.  The use of these techniques is a great asset when engaged in negotiating, and provides one with the benefit of leverage. This program teaches the use of tactical language that allows one to generate compliance and cooperation when dealing with difficult people, or when engaged in verbal conflict.  Students are taught to employ these techniques in order to maintain focus and control, defuse a potentially volatile situation, negotiate, and ultimately direct or alter a person’s behavior in order to obtain a desired result.
Staff Response Tactics & Techniques
The program provides guidelines for dealing with a number of possible workplace occurrences. Students are taught to employ safe tactics and proven effective techniques for dealing with incidents such as: Disgruntled PatronDisturbanceIntoxicated or Emotionally Disturbed PersonMissing/Abducted ChildDomestic Violence Incident/Fight; Illness/Injury; Theft; Active Shooter Incident. Because dealing with the public often requires knowledge of Conflict Management techniques, this program features a brief block of instruction on the use of Verbal Judo. Since it is a sobering reality that Active Shooter Incidents are increasing and can occur anywhere, a brief segment of that program is also included.
Senior Scams: Avoid Becoming a Victim of Scams that Target Seniors
This program explores a number of scams and confidence games that are routinely used to target senior citizens, including some of the newest con games. This workshop provides information on how to recognize, avoid, and respond to these scams.
