Yowann Tresidder Tonkin

United Kingdom Council for Psychotherapy (UKCP) Psychotherapist – Cornwall & Online

My name is Yowann Tresidder Tonkin, a UKCP-registered psychotherapist with over two decades in private practice. Based in West Cornwall and online across Britain, I provide a dedicated clinical setting for individuals navigating profound change, crisis, or transition. I offer an anchored, sober, and compassionate therapeutic presence—one that provides a sturdy container for those whose depth of inner experience requires a foundational ground from which to inhabit life with meaning, purpose and psychological maturity.

Grounded in extensive clinical formation, I provide a steady and experienced foundation capable of bearing and containing the complex states, conditions, natures, and needs so often reduced, bypassed, or pathologised by contemporary clinical and social perspectives and frameworks. This approach allows for both the clinical and compassionate attention required to integrate one’s experiences and facilitate foundational psychological change.

Through a synthesis of modern depth psychology and classical wisdom tradition, I provide a disciplined, substantive, and tempered psychotherapy to address the symptoms of anxiety, depression, and complex trauma—often the manifestations of a deeper structural fragmentation and existential exhaustion. This work is an active endeavour focused on the reclamation of wholeness—facilitating the re-orientation of the person toward an inner centre of integrity and the capacity to inhabit life with intentionality and purpose.

Clinical Areas of Focus

I bring a clinical and compassionate therapeutic presence to the following conditions and states of being, providing a disciplined frame for the recovery of innate human freedom and psychological agency:

  • Complex Trauma and Relational Dynamics: Engaging the pervasive dread, anxiety, and deep-seated shame arising from childhood trauma—including developmental neglect, childhood bereavement, family breakdown, institutionalisation, the profound pain of estrangement, Complex Post-Traumatic Stress (CPTSD), dissociative states, sexual trauma, and religious/spiritual abuse. I specifically address internal fragmentation and the “un-witnessed” nature of history with a tempered, protective, and compassionate presence, providing the clinical attention required to move beyond the constraints of traumatic history and integrate these experiences and conditions.

  • Neurological Diversity and High Sensitivity: Providing a specialised, non-deficit-based understanding of Autism Spectrum Conditions (including the profile formerly termed Asperger’s) and high perceptual sensitivity. I address the secondary trauma, exhaustion, and ontological isolation arising from chronic environmental misalignment—helping to bridge the gap between a unique psychic interiority and the stability required for a life of genuine agency and meaning.

  • Existential Disorientation: Addressing the weight of chronic depression and the profound loss of vital meaning that often accompanies transitions through mid-life and into old age. I work with the state of psychological disorientation that follows the fracturing of one’s foundational history—often through the silent pain of estrangement, the collapse of vocational identity, or the weight of existential despair. My practice offers a patient clinical frame intended to support the restoration of interior clarity and the capacity to inhabit a renewed life with a grounded, substantive adult maturity.

Professional & Vocational Landscape

  • Training, Research & Professional Standards: I trained as a psychotherapist in London at Regent’s University and the CCPE. This is enriched by a Diploma in Spiritual Direction (OXCACS, Oxford) and ongoing postgraduate study in Orthodox Theology (IOCS, Cambridge), due for completion in mid-2026. My clinical work is grounded in a profound respect for the inherent depth and integrity of the human person, drawing on a synthesis of modern depth psychology and the classical tradition of East and West. I provide a disciplined and inclusive framework for individuals of all faiths and none who seek substantial change.
    My practice aligns with Column C of the SCoPEd framework—the highest clinical tier recognised by the UK’s leading professional bodies. With over 10,000 hours of direct clinical practice, I am a UKCP-registered psychotherapist and a Senior Accredited member of the Association of Christian Counsellors (ACC), equipped to work at the necessary depth with complex trauma, structural fragmentation, and the unconscious. I maintain regular clinical supervision and operate strictly within the ethical frameworks of both the UKCP and the ACC. My practice is informed by ongoing academic and clinical research into the fracturing of the human psyche at the intersection of history, tradition, and psychotherapy

  • Stewardship: My work is deeply informed by both clinical and academic research into the safeguarding of the person’s vital interiority—specifically addressing the loss of familial proximity and the cycles of trauma transmitted across generations. My life as a husband and father, with a commitment to a depth of relational, educational, and spiritual formation within the family, provides a foundational weight to my understanding of relational stewardship. The absolute focus of this psychotherapy is the emergence, protection, and care of the essential core of the person—the locus of the fundamental freedom of the human person that remains untouched by, and in spite of, the traumas of the world—providing the necessary orientation towards the restoration of the whole person.

  • Vocational & Creative Life: Prior to my clinical psychotherapy training, I established a significant history in senior leadership and the direction of large-scale organisations. Supported by an MBA specialising in leadership and psychodynamic group behaviour, this background provides a disciplined understanding of the isolation and psychological toll—but also the vital responsibility—inherent to high-responsibility roles across public, private, and ecclesiastical contexts. I provide a grounded, non-dissociative presence for those contending with the realities of life within these spheres. This clinical work supports the restoration of a stable inner core of integrity, allowing the individual to meet the demands of their life not through exhaustion or persona, but from a place of anchored freedom and genuine agency. This understanding of identity and persona dynamics extends to my work with artists; as an accomplished and active musician, I bring a nuanced perspective to the internal pressures and boundary dissolutions often inherent to the creative life.

  • Continuity of Place: The website name Kova Kevenna is Cornish for ‘Deep Memory’. It reflects a clinical interest in the long-term, transgenerational effects of human displacement—the “deep memory” of the ruptures that have shaped the West. Informed by a familial relationship to place that spans a millennium, my work provides a vantage point and framework for analysing and understanding  how ancestral and cultural narratives shaped our experience of the world. This offers a stable, non-dissociative perspective for those contending with the modern sense of being ‘out of place’—where a life of external demand has resulted in a precarious detachment from one’s own history and foundational sense of belonging.

Practicalities

  • Location: In-person sessions take place at a private stone cabin in West Cornwall named Skovva (Shelter) set in peaceful and beautiful rural surroundings. This is easily accessible for those in Truro, Penzance, Helston, Redruth, and St Ives. I also offer online psychotherapy across Britain.

  • Session Structure: Sessions are 50 minutes, held at a consistent time each week.

  • Fees: The standard fee is £85. I do offer places as a pastoral provision on a sliding scale for those in financial or vocational restriction. Suitability for this work is the primary consideration; where a clear clinical suitability exists, I encourage enquiry regardless of financial limitation.

  • Emergency Support: This practice is not designed for acute-risk or emergency intervention. Please contact your GP or call 999/111 if you are at immediate risk.
