World champion.
33 professional world titles across forms, weapons, and point sparring. A competitive career built through years of practice and a return to the sport after spinal surgery.
Explore the competition record ↗I’m Jarrett Leiker. From the competition floor to the courtroom, my work is rooted in preparation, resilience, and helping others move forward.

Martial arts has been part of my life since I was three, learning from my parents, Jill and Bob Leiker.
Competition took me around the world. Coaching gave me a way to help others find their own potential. Law gave that same drive another purpose: standing beside people when they need an advocate.
Across each chapter, the through line is simple—show up prepared, keep growing, and put the work into something that matters.
