Jeffrey Fleury has been in the security industry for more than 33 years, of which 11 years were with the Singapore Police Force. He received the prestigious Long Service and Good Conduct Medal when he left.
He holds a specialised security science degree apart from other international security accreditations. He is an International Crime Prevention Specialist (ICPS) and a Certified Supply Chain Security Specialist (CSCSS). He has served as the Country and Regional Security Manager for established multinational companies for over 22 years, with security coverage and responsibilities spanning the Asia Pacific region — including Japan and Australia.
With regards to martial arts and other forms of combat training, Jeffrey has been involved with the arts for about 30 years. He holds black belts in Hapkido and Hanmudo and is versed in various other forms of martial arts and self-defense techniques. In 2018, he trained with knife combat expert Jim Wagner in Vancouver, Canada, and obtained his certification as a Knife Survival Expert Instructor.
What makes JF Self Defense different from other martial arts schools is what Jeffrey brings into the room — three decades of operator field experience, not just mat hours. The same situational reads that worked on the street, on protective details, in convoy and crowd management, become the curriculum. Civilians walk out with the same decision tools an operator uses, scaled to the situations they actually face.
The self-defense techniques he teaches are simple, direct and applicable. He believes that if you have to use physical self-defense you are already in damage-control mode. The best self-defense is improved self-awareness — not putting yourself in harm's way in the first place, so you are less likely to be selected as a target. The next best is to avoid the fight when one materialises. When neither avenue is left, you need to know how to fight to win.
That is why his workshops emphasise the soft skills first — posturing, communications, distance management — to prevent escalation into the physical stage whenever possible. Jeffrey has conducted programmes for multinational companies, schools, banks, aesthetic clinics and legal firms, in addition to the ongoing self-defence classes run from the JF studio on King George's Avenue. Most students arrive looking for technique. They leave with judgment.
