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.

Thank you for all the continued lessons and encouragement you provide. You are an amazing soul! Please thank Aria for all the good work she provides as well!

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.

For the past 6 months I've been studying the root cause of cancer & other health challenges with two of the best teachers in the world.

After taking level 1 & 2 I have completely dissolved two thyroid tumours on myself and completely eliminated my 8 year old French bulldogs Mast Cell cancer growths she had been dealing with for years.

Paul helped revolutionize my perspective on health and show me just how important emotional work is for creating powerful and lasting results.

He is a wealth of knowledge and an amazing person to be around. He's one of my biggest inspirations in the health field and in life in general. He is a wealth of knowledge and an amazing person to be around.

Many of you have messaged me privately to ask what coaching programs I have been taking this past year...

Well to this day, Paul Leendertse's Cancer Preventative Course, has been my fav!

With his teachings, I was able to help empower one of my friends to reverse his own cancer!!!

Paul Leendertse is the author and pioneer behind The Root Cause of Cancer, with over 16 years of dedicated experience exploring the link between psycho-emotional stress and the development of cancer.

Over the course of a decade, Paul worked closely with individuals with cancer (often late stage cancer) in immersive three-week residency settings where he consistently observed recurring patterns of unresolved emotional stress, trauma, and life challenges preceding cancer diagnoses. From these real-world insights, he developed a clear and transformative methodology rooted in his theory that a “psycho-emotional stress complex” underlies cancer and must be addressed for true healing to occur.

Paul’s comprehensive online Root Cause Assessment helps clients clearly identify these deeper emotional factors and map out a path for resolution, transformation, and healing. Many clients report significant shifts and decrease in symptoms - emotionally and physically - after just one session, and many clients have healed their cancer through the Root Cause Work.

Pauls work has evolved into a structured and practical approach to inner healing, taught in Root Cause Institute's two online programs: The Root Cause Course Level 1+ 2 and the Accelerated Self-Healing Course (ASC); Level 1+2 trains students to support others in their healing-from-within journey, and the ASC is designed specifically for individuals navigating cancer. Both include his groundbreaking 15-Step Real-Self Healing Process along with additional advanced tools for self-healing.

Whether you're seeking healing for yourself or looking to guide others, take the next step. Enroll in our programs or schedule a Root Cause Assessment, and be on the forefront of Root Cause Healing.

Aria's journey into holistic health and Root Cause Healing began through personal transformation. For many years, she faced addiction, chronic health challenges, and emotional distress. When conventional approaches offered limited answers, she made a profound shift - choosing to focus on self-love, inner healing, and personal growth. This decision was the beginning of a deep healing and awakening journey, which led to the reversal of her symptoms, renewed vitality, and a sense of lasting inner peace.

Through this transformation Aria developed a deep passion for addressing the root cause of illness. She spent years studying and practicing a wide range of healing modalities, including Emotional Healing and Bodywork in Switzerland, Holistic Lifestyle Coaching with the CHEK Institute in California, Yoga and Thai Yoga Massage in India, and other mind-body-emotion disciplines.

In 2019, Aria met Paul Leendertse and began supporting his immersive 3-week Self-Healing Retreats in Canada. Two years later, they co-founded the Root Cause Institute - an online school dedicated to exploring the emotional and psycho-spiritual foundations of illness and healing. Today, Aria co-teaches the Root Cause Courses and works directly with clients, offering Root Cause Assessments and supporting those who are ready to heal from within.

This course is for individuals navigating cancer or another serious health or life challenge.

It will help you clearly identify and resolve your Root Cause and guide you through the process of transformation.

As you heal, cancer or other illness can become a gateway to deeper self-connection and ultimately the creation of a life in which you are healthy, whole, and abundant.

The course includes 4 essential components:

1. Root Cause Education

2. Self-Love Practices

3. Practical Self-Healing Tools

4. Bi-Weekly Group Calls (Live & Recorded)

This course is the result of over 15 years of experience supporting hundreds of individuals in identifying and resolving Root Cause.

There is something profoundly powerful that happens when a group of individuals navigating cancer or other serious health challenge comes together - united in their commitment to uncovering and resolving the Root Cause, and healing from within.

This course is for individuals who are aspiring or established coaches, or professionals, who want to expand their practice. You can also take this course if you have cancer and are interested in becoming a coach after you heal.

Learn the Root Cause of Cancer in each Region of the Body based on our consistent observations with clients over the past 16+ years, along with the 15 Step Real-Self Healing Process - a potent tool for navigating life challenges and relieving the body of stressful emotions that may otherwise manifest as dis-ease.

Although the Course Material is designed with a primary focus on Prevention, students who had cancer when taking the course have reversed it (without treatments!), see testimonials.

Paul authored 'The Root Cause of Cancer' in 2012 and it's still one of the only books in the world not focused on supplements, treatments or ‘cures’. The book presents a different paradigm and highlights that physical approaches to destroying cancer, even if beneficial, can't address the Root Cause.

Destroying cancer in any way, commonly fails eventually because the factors that led to the development of cancer (The Root Cause) were not understood and resolved.

Unless a person understands what’s really caused their cancer, it's rare that they can make the necessary life-changes to heal and remain cancer-free long-term. You will learn why the only 'cure' may lie within the individual themselves, for important reasons.

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

The author, Paul Leendertse, has been working with clients with stage 3 and 4 cancer for over 16 years.
