The Founder

Learn from the Pioneer of the Root Cause of Cancer

Paul Leendertse

Author, Teacher, Coach, Pioneer

Paul Leendertse is the Pioneer and Author of 'The Root Cause of Cancer'.

He has over 15 years of rare experience helping individuals overcome significant health challenges - often stage 3 or 4 cancer. 

By living with individuals with Cancer for 3 weeks at a time, over a 10 year period, examining life-challenges, traumas, and lifestyle factors, Paul discovered the root cause of cancer and how to reverse it. The Root Cause is a psycho-emotional stress complex, effecting the physical body, which needs to be identified and resolved to heal.

Paul most often gets to the root cause of his clients cancer in one coaching session, and begins resolving it with them. Many times clients experience significant improvement of symptoms in their first session, and full reversal of cancer through Pauls Mentorship & Self-Healing Course.

Paul now teaches the Root Cause of Cancer to the world via his online trainings. To acquire advanced knowledge and skill in the Prevention & Reversal of Cancer, including Pauls 15 step Real-Self Healing Process, sign up for Root Cause Practitioner 1.

The following years Aria acquired skills in various modalities. Emotional Healing & Bodywork in Switzerland, Holistic Lifestyle Coaching with the Chek Institute in California, Yoga and Thai Yoga Massage in India, and more.

In 2019 Aria met Paul and began supporting his 3 week Self-Healing Retreat in Canada. Two years later they co-founded Root Cause Institute. Since then Aria has been co-creating and co-hosting Level 1 and 2 training, contributing to webinars, social media, and more.

A patient I've been working with just had their PET SCAN come back clear after several months of discontinuing chemo and doing this work to heal.

Stephanie, Naturopath
Paul is a trailblazer in the Root Cause movement, and his insights into the true causes of cancer are groundbreaking. 

I can personally attest to the validity of his teachings, as I successfully healed from stage 4 testicular cancer by addressing the root cause.  
Thank you Paul!
  As a western-trained physician, I have observed both professionally and personally, the need for approaching physical illness and disease through a more holistic and empowered lens.

Thank you for the amazing class today, I feel so honoured to be able to participate in your course - it’s literally what the world needs.

Best course I've ever taken, hands down, over the course of my entire professional career. Life changing both professionally, but more importantly, personally for me.

I am now working working toward sharing and guiding others using this unique, highly effective, life changing method of true healing.


The Root Cause of Cancer

The Book that's leading the paradigm shift

'The Root Cause of Cancer' is one of the only books in the world not focused on supplements, treatments or ‘cures’ because none of these approaches, even if beneficial, address the Root Cause of Cancer.

You will learn why the the only cure for cancer is within the individual themselves, for important reasons.

Unless a person understands what’s really caused their cancer, they can't consciously make the necessary life-changes to resolve it and remain cancer-free long-term.

Destroying cancer, in any way, commonly fails eventually, because the factors that led to the development of cancer were not resolved.

This book is essential for anyone who is ready to acquire the knowledge needed to understand the physical, mental, emotional, and spiritual factors associated with the development of cancer, to begin the self-healing process.

The author, Paul Leendertse, has been working with clients with stage 3 and 4 cancer for over a decade.

Will I be learning about GNM?

No. We do not teach GNM.

Pauls approach has developed from over 15 years of resarch into the lives of individuals with cancer, helping them identify and resolve significant stress, suppresed emotions, and create a life that truly noursishes them.

Much of what Paul has discoverd is contradictory to GNM. Our courses contain original material based on our own research.
