C: O: A: C: H stands for Castorian & Overdurfian Advanced Conversational Hypnocoaching!

Developed by John Overdurf and Martin Castor

Even more tools in one!

Master C: O: A: C: H is a fusion of the best tools found in modern professional hypnotherapy, NLP & HNLP, Coaching models, Body language, and small speech-based change processes.

These methods can be facilitated as hypnosis sessions with closed eyes or ordinary conversation with open eyes.

The master part is a powerful handful of extra and more advanced tools so you can handle any client situation successfully.

Three years of well-worked structure!

In the many years we have taught C:O:A:C:H in both Europe and the United States, we have always known that there would be a superstructure.

As we place great value in trying out and testing all the tools we use, we have spent three years making sure that the superstructure works and is 100% compatible with the COACH Practitioner. The tools must work, be practical and be free of anything "just" filling or indifferent knowledge. Therefore, the tools have been tested in coaching and hypnotherapeutic environments, with inspiring and lasting results. Even better is that all the techniques can be used individually in ordinary conversation. So our whole C: O: A: C: H model is an excellent tool for businesses and the like that do not necessarily have to do with therapy.

What is Castorian & Overdurfian?

John Overdurf is a legend in modern NLP, but the variant he calls HNLP. As one of Richard Bandler's first students, he is the only one allowed to have all of his students approved by Bandler. John Overdurf is also the favorite mentor internationally when talking about top 10 teachers like Melissa Tiers, Ken Guzzo, Steve Roehm, Martin Castor, and Igor Ledochowski.

Hence the term "The Overdurfian method" is a tribute to John Overdorf's way of thinking.

Castorian" comes from Martin Castor. It was named by many of his dedicated students from lectures and courses all over the world.

John and Martin have known each other for many years, and Martin is one of John Overdorf's few certified HNLP Instructors. Their common mindset and philosophy are the backbone of C: O: A: C: H. effect.
