Hi, I’m Jonathan Hewitt.


Welcome to Life Ki-do, where martial arts meets inner well-being. I’m so honored you found your way here.


The path to my own inner well-being was a long journey. Like many others, I grew up thinking that my happiness was dependent on how well I performed.


As an actor in television commercials, captain of three sports, and state wrestling champion, I was consistently  recognized for my accomplishments and accolades.


I soon realized my identity was wrapped in who I needed to be for other people. It was wrapped in what I needed to do to receive the attention in order to feel okay. It masked my insecurities and lack of self-love.


This realization kickstarted my journey into discovering the meaning of life and what it truly means to be happy. I delved into learning everything about meditation and mindfulness.


Through that journey, I learned that true happiness flows from the inside out. I learned what it means to become your own best friend and to truly love and respect yourself.


I discovered how to have intrinsic motivation to become who I wanted to be vs. having to rely on external validation.


I no longer felt the need to compare, compete, or control.

Instead, my consciousness grew and I became more compassionate and cooperative. As a result, my relationships with myself, others, and the world grew stronger and healthier.


I found my inner power — my River.

And now it’s my life’s work to help other people find theirs.


I’ve combined my 30 years of study in meditation, mindfulness, and the brain-body connection with a lifetime of martial arts training to create the Life Ki-do curriculum.


It truly lights me up the moment students discover the inner power they never knew they had access to.


It’s something you have to experience for yourself. Hope to see you soon!
