I've been working with someone navigating cancer, and I was so happy to hear that their latest PET scan came back clear. It's been a meaningful experience to support them through this part of their journey.

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!

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 toward sharing and guiding others using this unique, life-changing approach to self-understanding and spiritual growth.
JEREMY - NATUROPATH
For the past 6 months, I've been studying different perspectives on cancer and other health challenges with two of the best teachers I've ever learned from.

Taking Levels 1 and 2 has been an extraordinary experience. I've gained a completely different understanding of health and healing, and the impact this has had on my personal life has been profound.
KATIE - HEALTH COACH
After completing Levels 1 and 2, my understanding of health, healing, and the connection between our inner and outer lives has completely transformed.

I'm forever grateful for the wealth of knowledge Paul and Aria have given me. I now feel so much more confident in my ability to support myself and future clients on their own journeys of personal growth and well-being.
HEIDI - NATUROPATH
Paul helped revolutionize my perspective on health and showed me just how important emotional work is for personal growth and well-being.

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.
JOSEPH - Naturopathic doctor

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

Well, to this day, Paul Leendertse's course has been my favourite!

What I learned from Paul has been incredibly meaningful, and I've been able to use it to support a friend navigating cancer.

The Founder

Learn from the Pioneer of the Root Cause Work

Paul Leendertse

Author, Teacher, Coach, Pioneer
Paul Leendertse is the author of CANCER: BEYOND THE WAR and founder of Root Cause Institute, with more than 18 years of experience exploring the relationship between psycho-emotional stress, life experiences and cancer.

Much of Paul's perspective developed through working closely with individuals navigating late-stage cancer, including immersive three-week residency settings.

Through these experiences, he observed recurring patterns involving unresolved emotional stress, trauma, relationships and significant life challenges that clients described experiencing prior to their diagnoses.

These observations led Paul to develop what is now known as the Root Cause framework - his educational theory and approach for exploring the emotional, psychological, behavioural and spiritual aspects of health and illness.

For five years, Paul worked individually with clients through Root Cause Sessions, helping them explore emotional and life patterns they felt were relevant to their experience, while developing a personal path toward resolution, transformation and emotional well-being. 

Over the years, Paul's work has evolved into the educational approach now taught through Root Cause Institute's programs: the Advanced Self-Connection Course for individuals interested in personal growth and exploring their inner lives while navigating health challenges. and Root Cause Training for those interested in personal growth or learning how to support others.

Disclaimer: The Root Cause framework represents Paul's observations, experience and educational perspective. It should not be understood as establishing that particular emotional or spiritual factors are scientifically proven causes of cancer. The framework and associated educational programs do not claim to prevent, diagnose, treat, reverse, or cure cancer or other diseases, and are not substitutes for professional medical care.

Co-Founder

Aria Konrad

 Co-Founder | Personal Growth Mentor | Bodyworker
Aria's journey into holistic health and Root Cause Healing began through profound personal transformation. For many years, she faced addiction, chronic health challenges, and emotional distress. 

When conventional approaches offered limited answers, she made a significant shift - choosing to focus on self-love, inner healing, and personal growth.

This was the beginning of a profound healing and awakening journey, during which Aria experienced significant changes in her health and well-being, renewed vitality, and a deep sense of lasting inner peace she had never known before.

Her experience ignited a passion for holistic health and exploring the deeper emotional, psychological, behavioral, and spiritual aspects of illness and healing. She spent years studying and practicing a wide range of healing modalities, including Emotional Healing and Bodywork in Switzerland, Holistic Lifestyle Coaching in USA, Yoga and Thai Yoga Massage in India, and other mind-body-emotion disciplines.

In 2019, Aria met Paul Leendertse in Canada, and began supporting his immersive three-week Self-Healing Retreats. Two years later, they co-founded Root Cause Institute. Today, Aria co-teaches the Root Cause Courses and co-hosts the Group Coaching Calls.

Although the Course Material is designed with a primary focus on Prevention, students with cancer who have taken this course have reversed their cancer (without treatments!), see testimonials.

Note: If you have cancer and want to heal yourself, we recommend is to prioritize the Accelerated Self-Healing Course over taking this course.

CANCER: BEYOND THE WAR

Rethinking Cancer, Health, and Healing

CANCER: BEYOND THE WAR presents Paul Leendertse's perspective on cancer through a different lens - exploring physical, emotional, psychological, behavioural and spiritual aspects of a person's life rather than focusing exclusively on the disease itself.

Drawing upon Paul's experiences working with individuals affected by cancer, the book introduces the observations and theories that eventually became the foundation of the Root Cause framework.It invites readers to explore how unresolved emotional experiences, relationships, stress, behaviour and spirituality may relate to their personal experience of health and illness, while considering what healing from within can mean in their own lives.
Disclaimer: The ideas presented represent Paul's observations and educational framework and should not be understood as establishing scientifically proven causes or treatments for cancer.
