Kaja is the quality of teacher that makes you want to move to a different country just so you can train more with them. Kaja teaches in a way that is accessible to anyone, on any day. If you aren’t feeling top notch, she will work with you to make sure you get the most out of her class you can. The book Fear is the Mind Killer is a must have for any martial arts instructor. The chapters on understanding fear were especially useful to me as, due to several privileges, I haven’t had to confront those situations. Now I can recognize signs in my students and help create a space where they feel safe enough to participate and better themselves.

She has built a world class training school, created hundreds of passionate martial arts students and works tirelessly to make martial arts a better and more inclusive place. She is kind, compassionate and dedicated to making her students the best they can be. I am proud to call Kaja a colleague and mentor.
