Hi, I’m Thaddeus.

I’m a Dutch-born physiotherapist and manual therapist who moved to Norway, fell in love with a mountain in Aksdal, and decided that the medical system wasn’t the best place to actually help people get healthy.

That might sound strange. Let me explain.

The problem with healthcare

In 15 years of clinical practice, I noticed something. The medical system is excellent at diagnosing disease. It’s terrible at creating health. Those are two completely different things.

Sometimes the best intervention is no intervention. Sometimes the system designed to help you is the thing keeping you stuck.

I started studying Human Movement Sciences at university, but quickly figured out I didn’t want to spend my life in a laboratory wearing a lab coat. I wanted to work with people, not petri dishes. So I became a physiotherapist instead — and eventually a master manual therapist.

After 15 years in clinical practice, I left the clinic. Moved to a CrossFit, functional fitness, and Hyrox gym. And started helping people from the other direction — not by treating what’s wrong, but by building what’s right.

What I actually do

My work sits at the intersection of three things:

Clinical depth. I’m a registered physiotherapist and master manual therapist. I spent a decade and a half learning to read bodies — how pain works, why it persists, and what changes the conditions that keep it alive.

Performance science. Whether it’s CrossFit, functional fitness, or Hyrox, I understand how to push performance safely, how to scale intelligently, and how to coach movement with precision and care.

Flow neurobiology. I’ve studied the neuroscience of peak performance — the neurochemistry behind it. The five chemicals that make flow states possible, and the triggers that produce them reliably.

How I think

I read. A lot. Not for motivation — for mechanisms.

Chronic pain is a systems problem, not a thing to fix. You don’t catch the flu because a virus attacks you; your body sets up the conditions for it to flourish.

Humans get stronger from the right kind of stress. But well-meaning interventions can do more harm than good. Before adding anything, ask what you can remove.

Peak performance isn’t random or reserved for the gifted. It’s a neurobiological process with specific triggers. Biology scales. Personality doesn’t.

And the question that changed everything for me: instead of “what makes people sick,” ask “what keeps people healthy?” That’s the lens behind everything I do.

The personal bits

I live on a mountain in Aksdal, Norway with my wife, three kids, and a flock of Silkie chickens. I use a dumb phone by choice. I have a wood stove that I feed every morning. I believe sleep is the lead domino — before nutrition, before stress management, before exercise.

My core value is simple: do the right thing, as good as only you can. You’ll know what that is in any given moment.

And you might as well have fun while you’re here.
