   Ep 7: Beyond The Diagnosis: A Fresh Look at Childhood, Health, & the Freedom to Become with Dawn Lester

   In this episode of Know Thy Healing, I sit down with Dawn Lester for a wide-ranging conversation about childhood, health, parenting, environment, medical narratives, trauma, human potential, and what it truly means to raise and nurture healthy children. Dawn Lester is an independent researcher and author dedicated to uncovering the truth behind the prevailing narratives that shape our understanding of the world. Following a decade-long, deep-dive investigation into the nature of health and disease, Dawn co-authored the seminal work What Really Makes You Ill? Why Everything You Thought You Knew About Disease Is Wrong. Her writing bridges the gap between complex investigative research and accessible insight, challenging readers to question the foundations of everything they have been taught. Dawn’s work is driven by a commitment to empowerment, encouraging us to take full responsibility, not only for our own well-being but for how we raise, protect, and nurture our children. She advocates for a return to critical inquiry, urging everyone, especially parents and caregivers, to look past official dogma and rediscover our true, innate potential as human beings. Her latest book, A Fresh Look at Childhood Illness, builds upon her previous work and discusses the many reasons for placing a strong emphasis on our approach to raising and nurturing children in all areas of life, not just health. Together, we explore the importance of the environments children grow up in — physically, emotionally, mentally, and socially — and how stress, family dynamics, instability, trauma, lifestyle, and other environmental influences can shape a child’s behavior, health, development, and ability to adapt. We discuss the ACE studies, childhood diagnoses such as ADHD and oppositional defiant disorder, and whether many diagnostic labels can obscure the deeper context of what a child has experienced or the environments they are being asked to adapt to. We also explore children who simply do not fit comfortably into the conventional mold of sitting still, following rigid schedules, staying indoors, conforming, and behaving exactly as expected. From there, we move into vaccinations, the vitamin K shot, circumcision, food, medicine, navigating the medical system, and the practical choices parents face when trying to create healthier environments for their children. The conversation also takes on a deeper philosophical and spiritual dimension as we explore how we should understand children in the first place — not as beings to shape and control, but as individuals with their own nature, potential, and path. We talk about trauma, identity, awareness, faith, and the distinction between experiencing something and becoming identified with it. Difficult experiences can be acknowledged and learned from without becoming the defining story of a person’s life. At its core, this episode is about raising children with greater awareness, discernment, responsibility, and trust — creating the conditions for them to thrive physically, emotionally, mentally, and spiritually while allowing them the freedom to become who they are meant to be.

   Ep 6: Rewrite the Story: Mindset, Victimhood & the Trauma Industrial Complex with Mark England

   In this episode of Know Thy Healing, I sit down with Mark England — TEDx speaker, mindset coach, and co-founder and head coach of Enlifted — for a powerful conversation about the stories we tell ourselves, the language we use to construct our reality, and what becomes possible when we realize those stories can be changed. Mark has spent nearly two decades studying the relationship between words, breath, mindset, and personal transformation. His definition of mindset is beautifully simple: the stories we believe about ourselves and our lives. We explore how these stories often operate beneath conscious awareness, quietly shaping our identity, relationships, choices, and sense of what is possible. Mark walks us through Enlifted’s practical approach to bringing those narratives into the light — slowing down our speech, becoming aware of the breath, writing the story down, naming it, speaking it aloud, and beginning to see it from a different perspective. One of the central themes of our conversation is the movement from victimhood into agency. Not through denying what happened, assigning blame, or pretending suffering isn’t real, but through recognizing that regardless of what we’ve experienced, we still have choices in how we write the story moving forward. What I especially appreciate about Mark’s approach is that it isn’t built around deciding whether a story is morally “right” or “wrong.” The deeper question is simply: Is this the story you want to continue living inside? And if it isn’t, what might become possible if you chose another? The conversation also moves into the difference between the organic suffering that is inevitably part of being human and what Mark refers to as the “trauma industrial complex” — his critique of the ways trauma can become an identity, an industry, or an endlessly reinforced narrative rather than something we acknowledge, integrate, and ultimately move through. We explore therapy, psychoanalysis, trauma bonding, self-responsibility, faith, breath, language, and the danger of making our wounds the center of who we believe ourselves to be. At its core, this episode is about simplicity. The stories we tell ourselves matter. The words we use matter. The breath beneath those words matters. And perhaps one of the most liberating realizations is that the story you’ve been living is not the only story available to you.

   Ep 5: From Germ Theory to Terrain: Rethinking Disease, Microbes & Healing with Jacob Diaz

   In this episode of Know Thy Healing, I sit down with terrain-based naturopath and researcher Jacob Diaz, known online as @undercovervirologist, for a wide-ranging conversation challenging many of the assumptions underlying conventional ideas about health, disease, microbes, and healing. Jacob shares his journey into the terrain perspective and how it fundamentally changed the way he understands both acute and chronic illness. Rather than stopping at a diagnosis, we explore the importance of looking at the entire history and story of the individual — physical stagnation, emotional patterns, environmental exposures, structural changes, previous medications and surgeries, oral health, and the many influences that shape a person’s internal terrain. We discuss the history of allopathic medicine, homeopathy and the historical homeopathic hospitals, antibiotics and the microbiome, scar tissue and structural restriction. Jacob also walks us through the kinds of questions he asks clients and why the story behind the diagnosis reveals far more than the diagnostic label itself. From there, we move into the pseudoscientific nature of virology, the silliness of contagion experiments, germ theory, genetics, and the conventional interpretation of bacteria, fungi, and parasites. We discuss his critiques of the experimental methods and assumptions used to support conventional models of infectious disease, as well as the true nature of microbes, fungus, and parasites, not as pathogenic entities to be feared, but as helpful participants restoring balance to the inner ecology of our body. We also explore homeopathy, isopathy, homotoxicology, cranial osteopathy, chiropractic and bodywork, along with the profound connection between oral health and the rest of the body. But underneath all of these subjects is a much deeper theme: agency. The terrain perspective asks us to move beyond seeing the body as defective or helpless and instead begin listening to symptoms as messages. It asks us to examine the conditions in which those symptoms arose, take responsibility for the terrain we are creating, and restore faith in the body’s inherent capacity to regulate, adapt, repair, and heal. At its core, this episode is about looking beyond the diagnosis and learning to read the deeper story the body is trying to tell.

   Ep 4: The Science of Unlearning: Terrain, Nature & the Return to the True Self with Liev Dalton

   In this episode of Know Thy Healing, I sit down with Liev Dalton — researcher, educator, former therapist, and longtime student of health, philosophy, natural law, and the terrain perspective — for a wide-ranging conversation about science, healing, Nature, consciousness, and the art of unlearning. Liev originally studied Biochemistry and Molecular Biology at Dalhousie University with plans of becoming a dental surgeon before eventually changing course and completing a Master’s in Counselling Psychology. He went on to build a therapy practice incorporating wilderness therapy, EMDR, mindfulness, somatics, and related approaches. But through both his formal education and his own independent inquiry, he began asking increasingly uncomfortable questions about the foundations of what he had been taught. We explore what happened when Liev began going back to the original experiments, studies, and assumptions underlying many of the scientific claims he had once accepted as settled. Rather than just questioning conclusions, he began questioning the logic, controls, methodology, and premises beneath them. That inquiry eventually led him toward the terrain perspective — a framework he initially set out to challenge and falsify, only to find himself moving increasingly toward it. We talk about the difference between accumulating information and actually knowing — the possibility that genuine knowledge is less something we acquire from outside ourselves and more something we remember when enough conditioning, complexity, and intellectual noise have been stripped away. We explore the return to simplicity, Nature, God, and the innate intelligence of life. We also move deeply into the philosophy of science itself: reductionism versus holism, the limitations of studying isolated parts outside the living whole, the difference between chemistry and alchemy, the tendency of modern science to become so focused on the test tube that it misses the organism, and the question of whether a science built largely upon dissecting and analyzing dead matter can actually explain life. Liev shares his perspective on vitamins as laboratory-created abstractions, scientific controls, logical fallacies, and what he sees as the danger of allowing scientific models to become unquestionable dogma rather than hypotheses continually subjected to scrutiny and falsification. And then the conversation shifts again — this time inward. We talk about trauma, thought, identity, and the limitations of endlessly psychoanalyzing the past. Rather than spending our lives continually excavating old wounds, we explore the possibility of acknowledging what happened without allowing it to define the present. Every thought, as Liev puts it, can be seen as an offer rather than a command. The mind continually constructs stories about a past that is no longer here and a future that has not yet arrived. But peace is only ever found now. Healing is only ever happening now. And beneath the layers of conditioning, identity, fear, and thought, there may already exist something whole — the True Self that was never actually broken in the first place. Often the path to knowledge begins not by learning more — but by becoming willing to unlearn.

   Ep 3: Holistic Spirit: From Culture and Conditioning to Courage and Creation with Ste Lane

   In this episode of Know Thy Healing, I sit down with Ste Lane — holistic health coach, former rugby player and MMA fighter, father of two, musician, homesteader, and host of Heart & Soil’s Radical Health Radio — for a wide-ranging conversation on health, culture, Nature, purpose, and the deeper art of living. Born and raised in England, Ste’s life has taken him through sport, travel, Southeast Asia, profound experiences with plant medicine, fatherhood, raising his own animals, and an increasingly intimate relationship with the land. His path has been anything but linear, and that becomes one of the central threads of our conversation. We explore the idea that culture and society function almost like an operating system — a set of assumptions, beliefs, expectations, and behaviors we absorb long before we are conscious enough to question them. From there, we talk about what it means to step outside of that programming, encounter life directly, and embark on something resembling the archetypal hero’s journey. We move into the importance of allowing energy to find its proper expression, the deeper spiritual and philosophical dimensions of health, and the ways the mind can create unnecessary friction by constantly imposing expectations onto reality. We talk about wu wei, surrender, presence, and what becomes possible when we stop trying to force life into the shape we think it should take. At the heart of the conversation are Ste’s Four Directions of Health: nourishment, elimination, movement, and creation — a beautifully simple framework for understanding the fundamental ways in which life takes in, lets go, moves, and expresses. At its core, this episode is about living in deeper relationship with Nature, with ourselves, and with life as it actually is — rather than endlessly fighting against it.

   Ep 2: Addiction to Awakening: Sobriety, Spirituality & the Search for God with Phil Sell

   In this episode of Know Thy Healing, I sit down with one of my oldest friends, brothers, and fellow travelers in sobriety for a deeply personal conversation about addiction, recovery, spirituality, and the search for God. We share stories from some of the darkest chapters of our lives — drug addiction, destructive habits, self-sabotage, and the strange ways we tried to escape ourselves — while also reflecting on what those experiences eventually forced us to confront. From there, the conversation moves beyond sobriety itself and into the deeper questions underneath addiction: What are we really searching for when we reach outside ourselves for relief, stimulation, numbness, or escape? Is addiction only about substances, or can it be understood as a distorted attempt to find connection, meaning, wholeness, or even God? We talk openly about our own shifts from atheistic skepticism into spirituality, and the ways science, philosophy, personal experience, and the esoteric gradually began to overlap. We explore consciousness, faith, purpose, the nature of reality, the importance of an open mind, and the willingness to question one's own belief systems. This episode is raw, vulnerable, and at times deeply personal. It is less about presenting answers and more about tracing the path that led both of us to ask better questions — about addiction, identity, God, truth, and what it means to live without constantly reaching for something outside ourselves.

   Ep 1: The Art of Medicine: Rhythm, Resonance & the Return to Harmony with Dr. Tommy Hughes

   In the first episode of Know Thy Healing, I sit down with my good friend and Doctor of Chinese Medicine, Tommy Hughes, for a conversation that moves far beyond surface-level health. We explore Chinese medicine not as a collection of techniques, but as a living philosophy rooted in rhythm, resonance, harmony, and relationship. Tommy helps illuminate where Chinese medicine is often misunderstood, why symptoms are not the deepest layer of disease, and why true healing begins by understanding the causal imbalance beneath the outer expression. We talk about qi, chronic illness, constitutional medicine, and the forgotten art of the physician — not merely as someone who manages disease, but as someone who understands the individual, reads patterns, and helps restore alignment between the person and the greater order of life. From there, we move into one of the most beautiful threads of the conversation: the relationship between medicine and music. In Chinese thought, healing and music are deeply connected through rhythm, tone, resonance, harmony, and the ability to restore order where there has been disharmony. We also explore wu wei, yin and yang, ancient longevity, cyclical patterns, cosmology, and the deeper intelligence woven into Nature itself. At its core, this episode is about remembering that medicine is not meant to be a war against the body. It is the art of helping life return to harmony.
