Welcome

Hello! I’m Kaja Sadowski, a martial arts instructor and writer based in Vancouver, Canada. I teach people of all backgrounds how to fight with fists, feet, and swords, and I write about coaching, self defense, and community building. I want to make fighting and the strength it brings accessible to everyone. Join me.
