Master Instructor Torin Hill began the TORIS organization to categorize the research findings from disparate fields related to human injury, and develop training curricula to use that research for tactical advantage. By recognizing the value of injury biomechanics, sports injury and emergency medicine as empirical data sources, he has refuted historical soft-science and martial mythology—and instituted a paradigm shift from self-defense and fighting to the objective goal of debilitating injury in lethal force settings.

In addition to the requisite training and teaching to become a Master Instructor, Mr. Hill has had direct involvment in the training and examination of 30 Instructors, collaborated in the development and evaluation of 4 Master Instructors, and directly trained law enforcement, military, and civilian sector clients numbering in the thousands—which uniquely qualifies Mr. Hill as an expert in human movement mechanics, as it applies to teaching debilitating injury.

Mr. Hill founded the criteria for written personal accountability and risk management testing in personal lethal force training. He also pioneered both the uniquely-integrated firearms and personal lethal force training and the use of human motion synthesis animation for the prescriptive teaching of debilitating injury and resulting body dynamics that define the TORIS product offering.

The chief editor of Practical Injury: Sites, Mechanisms, and Results and co-author of Human Collision Injuries, Mr. Hill has authored monographs on the Criteria for High-Density Training and co-developed monographs on Striking, Joint-Breaking, and Throwing. He is a principal developer of the distinction between Antisocial Aggression and Asocial Violence in this domain.

Using programs created through TORIS, Mr. Hill has taught members of multifarious Military and Law Enforcement agencies, including the Federal Bureau of Investigation, the Department of State Diplomatic Security Service, California Highway Patrol, and the US Border Patrol. He created and delivered a presentation entitled: "The Sites of Injuries and Their Effects" to top US Customs and Border Protection personnel, and has taught multiple seminars domestically and internationally: New York, Dallas, Phoenix, Las Vegas, San Diego, Hong Kong, and at the Federal Law Enforcement Training Center in New Mexico.

Mr. Hill is a NRA Certified Instructor and Range Safety Officer, and currently the Director of Training for the TORIS organization.
