The Founder

Learn from the Pioneer of the Root Cause Work

Paul Leendertse

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

Paul gathered rare knowledge by working closely with individuals with late stage cancer in three-week residency settings - with great success. With all of his clients he examined lifestyle factors as well as emotional factors and made profound observations: Every time a clear and consistent pattern of unresolved emotional stress, trauma, and life challenges preceded his clients cancer diagnoses, and when those stressful factors were resolved successfully, their cancer disappeared. From this lived experience Paul created a concise methodology rooted in his theory that a “psycho-emotional stress complex” underlies cancer and must be addressed for true healing to occur.

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

Over the years Pauls work has evolved into a practical approach to healing from within 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 ASC is designed specifically for individuals navigating cancer. Both courses include his groundbreaking 15-Step Real-Self Healing Process along with further advanced tools for self-healing.

Co-Founder

Aria Konrad

 Co-founder, Self-Healing Mentor, Bodyworker
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 she hadn't known before.

This experience ignited her deep passion for holistic health and understanding and resolving 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 3-week Self-Healing Retreats in Canada. Two years later, they co-founded Root Cause Institute - an online school dedicated to 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.

The Root Cause of Cancer

The Book that's leading the paradigm shift

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.
