Our team

The Faculty on the journey, Frédéric Cherri

By nature, I’m not very fond of labels or titles. However, if I had to describe my path I would say that I’m mostly a practitioner of the shamanic arts, a therapist with 30yrs of clinical practice and tutoring in the field of cranial osteopathy, specialising in trauma, immune disorders and perinatal issues. I’ve also trained extensively for the last 25 years in the shamanic arts, and dedicated much of my time to living and studying with indigenous communities in many parts of the world.

I’m finally an entrepreneur, a retreat leader, a program teacher, a ceremonialist, a shamanic practitioner, an entheogen integration specialist and a personal coach. Years of study and practice on the path of workshop facilitation, field research and clinical & therapeutic work have led me to believe we can heal anything.

I’m also aware of being a bit of an ‘oddball’ in the realm of ancestral medicines, as I’ve trained (and keep training) in a variety of medicines and within different traditions. A medicine man or woman is usually a one-medicine specialist and trains in one sole tradition. I have answered the specific calls from some of these remarkable medicines and travelled wide and far to different jungles and mountains to work and study with varied first-people communities on this planet.

I believe there is a need for people like me to help bridge, protect and disseminate to a western audience the extraordinary wisdom of the first nations who share these medicines. Shamanic work and one of its mysterious and exciting aspects, the realm of plant or earth medicine, brings many answers to the unresolved issues of modern medicine or psychology. I have dedicated my life to supporting others’ journeys, growth, and transformation and am delighted to answer any questions via Zoom or WhatsApp chat. Schedule a free call here.

Support and assisting team

Exceptionally, and for each one of these individual ceremonies, we will have the pleasure to add to our assisting team a list of recently graduated practitioners, extensively trained in the art of preparation, delivery of the experience and integration, and for each one of these sacred medicines. They will all contribute to your experience and make sure you journey in the best and safest conditions.
