The Founder

Learn from the Pioneer of the Root Cause Work

Paul Leendertse

Author, Teacher, Coach, Pioneer
Paul Leendertse is the author of The Root Cause of Cancer 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.

These observations led Paul to develop what is now known as the Root Cause framework—his educational theory and methodology for exploring the emotional, psychological, behavioural and spiritual dimensions 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 healing from within.

Over the years, Paul's work has evolved into the educational approach now taught through Root Cause Institute's programs: the Accelerated Self-Healing Course for individuals focused on their own healing journey, 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.

Co-Founder

Aria Konrad

 Co-founder, Self-Healing 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 marked the beginning of a profound healing and awakening journey, during which Aria experienced a complete resolution of her symptoms, a profound transformation in her physical health and vitality, and a deep sense of lasting inner peace she had never known before.

Her personal transformation ignited a passion for holistic health and exploring the deeper emotional, psychological, behavioural, and spiritual aspects of illness and healing.

She spent years studying and practising 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—an online school dedicated to exploring the emotional, psychological, and psycho-spiritual dimensions of health, personal transformation, and healing from within.

Today, Aria co-teaches the Root Cause Courses and co-hosts the Group Coaching Calls included with Root Cause Institute's training and Self-Healing Program.

The Root Cause of Cancer

The Book that's fueling the paradigm shift

The Root Cause of Cancer presents Paul Leendertse's perspective on cancer through a different lens—one that explores the physical, emotional, psychological, behavioural and spiritual dimensions 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.
