My name is Yowann Tresidder Tonkin. I am a UKCP-registered psychotherapist based in Cornwall, offering both in-person and online psychotherapy. I guide and support people through periods of profound psychological crisis, suffering, transition, and transformation.

With over 18 years in private practice, I specialise in anxiety, depression, and complex PTSD, and I work compassionately with those experiencing emotional emptiness, loss of meaning, and despair to foster lasting psychological change, emotional growth, and deeper self-understanding and purpose.

My clinical foundation is in depth psychology, drawing on psychoanalytic, Jungian, and psycho‑spiritual (transpersonal) approaches. I trained at Regent’s College and the Centre for Counselling and Psychotherapy Education (CCPE), and I maintain regular clinical supervision adhering to UKCP ethical standards.

A distinctive aspect of my work is the integration of depth psychology and spirituality. I hold postgraduate qualifications in psychotherapy and counselling, plus qualifications in Spiritual Direction/Pastoral Theology (OXCACS, Oxford) and Orthodox Theology (IOCS, Cambridge). I continue research at the intersection of ancient spiritual tradition, pastoral theology, and psychological practice.

My psychological work supports people affected by family breakdown and estrangement, adult and childhood bereavement, emotional, physical, and sexual trauma, marital difficulties, emotional burnout, religious and spiritual abuse, marginalisation or persecution, attachment difficulties, relational ruptures, and existential disconnection. I am experienced in supporting people moving through midlife and later life, focusing on psychological maturation during complex periods of struggle and change.

I have a deep clinical understanding of autism and neurodivergence, and I bring both expertise and compassion to the psychological and spiritual dimensions of inner life. I am especially attuned to how ways of perceiving shape emotional experience, spirituality, and encounters with mystery. By weaving therapeutic insight, psychological depth, and spiritual reflection, I walk alongside people as they grow in resilience, self-awareness, and psychological maturity.

My psychotherapeutic approach works with historical and transgenerational trauma using depth psychotherapy to undertand and heal inherited patterns, restore family and cultural connections, and strengthen individual resilience and belonging..

Before training in depth psychotherapy, I worked extensively in the business sector. I hold an MBA in organisational leadership and psychodynamic group behaviour and undertook doctoral research (DBA) in this area before redirecting my studies to depth psychology and psychotherapy in 2004. This background informs my therapeutic work with leaders in public and private sectors, supporting self‑awareness, psychological maturity, and vocational development.

I am a husband and father, committed to family life, which informs my understanding of relational dynamics, childhood and adolescent development, and parental and adult formation. I am also an accomplished musician and have provided therapeutic support to artists and people working in the creative industries.

The consulting room is in a tranquil rural setting in southwest Cornwall, accessible from Truro, Falmouth, Penzance, Helston, Redruth, and St Ives. Engaging in depth psychotherapy requires a genuine need and willingness for change, self-awareness around psychological difficulties, and a readiness to assume responsibility for inner development.
