About
Built from experience, not theory alone.
SENTINEL was developed by Luke Wiltshire, the creator of the SENTINEL Framework and a violence, behavioral risk, and personal safety educator based in British Columbia, Canada.
The framework comes from three areas that rarely get taught together: combat sports, frontline work, and behavioral risk analysis. It is designed for people who need practical tools for reading risk, making decisions under stress, and leaving before violence becomes unavoidable.
Luke's background in MMA, boxing, Muay Thai, jiu jitsu, and competitive fighting shaped the physical side of SENTINEL: distance, timing, anatomy, pressure, and the difference between sport violence and real-world violence.
His frontline work in mental health, addiction, outreach, and clinical support shaped the human side: distress, escalation, volatility, shame, manipulation, and the limits of verbal de-escalation.
His experience in security and confidential high-stakes environments shaped the operational side: preparation, pattern recognition, discretion, threat assessment, and exit planning.
SENTINEL exists because people should not have to become paranoid, aggressive, or physically dominant to become harder to harm. The goal is simple: see earlier, think faster, and leave sooner.
