I have worked with Kasper and witnessed pieces his life. I have met no teacher to date who has grasped the concept of education better than he has. His work will get you to your own personal place of empowerment and creativity.

Kasper taught me to listen to the body and respond to my needs, while growing control of my fight-or-flight vs. rest-and-recover systems to my needs. The truly great thing about learning from Kasper is the effectiveness of his explanation and teaching. By lifting the curtain of the science so simply and understandably, I found it super easy to decide which methods could be used where in my training and performance preparation.

Kasper always asks the right questions, quickly discerning where the patterns of behaviour have been formed and which solutions there are for certain life blocks. He is pragmatic, yet playful, serious, yet childlike, well informed yet not fixed in his thoughts. And he understands that being a teacher is being a student, which is why his passion in teaching really shines.

I have been testing the most cutting edge biohacking methods for over 20 years. However, what I learned from Kasper in a single weekend inspired me to dedicate myself daily to these tremendously effective principles. Not only to propel my successful dance career further, but to enhance my life in all areas. Kasper breaks down the complex into the practical, in an inspiring way. If you are serious about personal development, find this guy!

I invited Kasper to teach at one of the Ziva Meditation retreats and he rocked it! His ability to communicate a large amount of complex knowledge in a short period of time is stellar. Everyone who experienced the breathing exercises were moved by their intensity and how great they felt afterwards… including me. I am personally inspired by his story of dealing with his own pain and healing. Watching him dance the dance between father and entrepreneur has been a lesson for me as I move into motherhood. I highly recommend working with him!

Kasper is not only an amazing, humble, kind, generous human being… but he is also one of the best all around teachers I have ever encountered in all my days of education. The Deep Dive Retreat was hands down one of the most profound and life changing things I have ever done. It was not just his ability to explain and show his methods, but it was his attention to each individual.  He has all the knowledge in the world, but he allowed us all to find our own method and take away from it what we needed. I could say this again and again, but there is nothing better than Kasper’s teaching.

Kasper has the advantage of seeing the underlying principles and putting them into plain English. As an experienced science teacher, he’s trained in breaking down complex ideas into bitesized and digestible chunks. He’s probably the best person to learn this stuff from.

Through all of the education in my life in the fields of science, biology and chiropractic school, Kasper has excelled as one of the best. He is masterful at taking complex topics and making them simple. He uses innovative education techniques to teach in creative and empowering ways. If you want to be a better human and optimize your potential, just spend some time learning from this guy.

Kaspers inspiring teachings opened my eyes to some amazing abilities of the human body that I had never even heard of. His applicable techniques and clear cut explanations of the scientific background were highly impressive to me and my athletes. The applications for athletic performance, active recovery and general well-being make for an absolutely invaluable set of tools for any athlete.

Kasper is one of my top life teachers! I felt total support and trust in Kasper’s instruction. He has an amazing depth of knowledge and was able to inspire me to want to know the science that supports these methods. Whether we were practicing breath, meditating in 33 degree water or studying biology, Kasper knew his stuff and in the end, made sure we did. My training with Kasper has been transformative and life changing.

Kaspers combines knowledge, cleverness and humor with a direct yet compassionate attitude. I remember thinking “man, this guy really gives a sh*t.” I follow several key players in the biohacking scene and Kasper is by far the most authentic, articulate, and insightful. As much as he has changed his own life for the better, he has also unlocked the ability to share those methods in fresh and impactful ways. He is a teacher as well as a role model, and that is truly a gift in this modern day and age.
