“I started with Tjeerd quite a while ago and had already written a review back then. But after many follow-up workshops I feel it’s important to share again: this is something you really need to experience.

What I’ve encountered with Tjeerd goes far beyond a ‘breathing exercise’. It’s a journey inward. He guides you with so much calm, knowledge, and trust that you can fully surrender to the process. The setting is safe, pure, and healing — everything is allowed to be there.

For me personally, this breathwork has opened doors I kept closed for years. I’ve released what was stuck, found new energy, and gained clarity about my path. It feels like I’m not just breathing anymore, but finally truly living.

If you’re doubting: give this to yourself. Breathing sounds simple, but the way Tjeerd guides it is genuinely unique. This is not a luxury or a hobby — it’s an investment in yourself.

Thank you, Tjeerd, for your dedication and the special experience you offer time and time again.”

Nico van Velsen

“Pleasantly surprised by the results after seven insightful sessions on breathing related to stress. Learning how to bring yourself into a state of calm using something you do all day long.

Thanks to the great guidance and clear explanations about breathing and its positive effect on your mindset through The Breath Wave, it has had a big impact on my well-being and awareness.

Thank you so much, Tjeerd!!”

Annemarie (The Hague)

“I followed a 6-session coaching program with Tjeerd. He is an incredibly warm and grounding coach with a calm, relaxed energy. The personal guidance he offers felt exactly right, and he made sure I felt completely at ease during every session.

Thanks to his extensive knowledge, I gained many new insights and now experience much more inner peace. If you’re interested in breathwork techniques, I can wholeheartedly recommend Tjeerd. His calm approach and broad expertise have given me valuable tools for everyday life.”

Marcel (Nieuw Vennep)

“I completed a coaching program with Tjeerd that included breathing exercises, ice baths, and personal conversations. It was a beautiful inner journey that helped me reconnect with my feelings.

Tjeerd’s guidance is excellent. He explains clearly how breathing works and gives exercises I can do at home. He is open and honest. I can recommend this to everyone!”

Ferry ten Brinke (Amsterdam)

“After joining a Wim Hof group workshop led by Tjeerd, I followed several 1-on-1 sessions with him. My breathing was too shallow/high, and through Tjeerd’s techniques I’ve learned to bring it under control.

We ended the six sessions with an ice bath, again a great experience. I can recommend Tjeerd’s sessions to everyone. They have helped me tremendously.”

Sjef Klijberg

“Tjeerd deserves a full five stars for the 1-on-1 session we did. His attentive guidance and his ability to sense exactly what was needed at each moment gave me a lot of trust and confidence during the session.”
