A retreat and gatherings organisation dedicated to the conditions under which genuine transformation becomes possible.
One Sanctum is a retreat and gatherings organisation dedicated to the most serious question available to any human life.
It is not a wellness brand in the conventional sense. It does not traffic in the pleasant surfaces of rest and restoration, though rest and restoration are part of what it offers. It is not a conference, though it gathers some of the most significant thinkers, healers, and researchers of our era. It is not a therapeutic programme, though transformation — genuine, cellular, lasting — is what it is built around.
One Sanctum occupies a different category: a curated sanctuary for depth. A carefully constructed container in which extraordinary human beings — those who have dedicated their lives to understanding the meaning of deep rupture, consciousness, the body, the psyche, the ecological world, and the nature of human flourishing — gather with a select community of participants who are ready to be genuinely changed.
The name is deliberate. Sanctum: a place apart, set sacred, protected from the ordinary noise of the world. One: because the work that happens here is always, ultimately, about connection — to self, to others, to something larger than the individual story we have been telling about who we are. It is about returning to the one container that holds us all.
One Sanctum was founded by Lara from inside a world she knows intimately. She spent decades observing what extraordinary material comfort cannot touch — the estrangements held together by performance, the carefully managed pain, the particular loneliness of people surrounded always by others and seen, almost never, by anyone. She came to understand that the people with the greatest power to shape the conditions of human life are often the least equipped — by the very systems that elevated them — to feel the weight of what they are shaping. That vulnerability, in the culture of privilege, is treated not as a human inevitability but as an existential threat. And that this costs everyone.
The wounds people carry move outward — into relationships, into institutions, into politics, into the decisions that determine how resources are distributed and whose suffering matters and whose doesn't. Healing, in this framework, is not a private matter. It is, potentially, a political one.
One Sanctum is designed to speak fluently in the language of the world it serves — intellectual rigour, aesthetic excellence, discretion, the company of peers — not to flatter it, but to lower the threshold of entry. Because the healing cannot begin until the person is willing to step inside.
What Lara has seen, across decades of this work: the consequences do not stay contained within them. The moral imagination expands. Wealth stops functioning as a mechanism for separation. It begins, instead, to feel like a responsibility — a means back into the human story rather than a reason to stand apart from it.
This is why One Sanctum exists. Not to serve those with the most at the expense of everyone else, but because the healing of those with the greatest power to shape the conditions of human life is not a privilege for them alone. It is, potentially, a gift to all of us.
Not the weekend workshop with its crowded schedule and insufficient integration time. Not the online summit that can be consumed passively from a sofa. A multi‑day immersive gathering, away from ordinary life, with a small group of thoughtfully selected participants and a faculty of genuine depth — this is something different.
Each retreat is a progression, not a programme. The intellectual and the somatic interweave. Participants are not passive recipients of expert knowledge — they are active participants in their own unfolding. The group itself becomes a resource.
This is Lara's foundational conviction, distilled from decades of knowing: put the right people together in the right conditions, and something happens that none of them could have produced alone.
A place apart, set sacred, protected from the ordinary noise of the world — and the one container that, finally, holds us all.
Lara Tambacopoulou is a systemic and transgenerational psychotherapist, Family Constellations facilitator, and certified psychedelic‑assisted therapist. For more than two decades, she has worked at the intersection of trauma, attachment, and inherited pattern — with individuals, groups, and the relational fields between them.
Her clinical training spans Family Constellations training at the Centre for Systemic Constellations in London, three years of psychedelic studies through the AWE Foundation, and extended immersion with indigenous communities in Central and South America — traditions in which healing, ceremony, and community have never been separated. She holds an MBA, an MA in Communications, and a counselling degree from the University of British Columbia.
She has worked in countries where expanded states of consciousness are legally supported as therapeutic tools. She has sat with people in the dissolution of old identity and the frightening, exhilarating emergence of something new. She has navigated the territory of transgenerational trauma — the wounds that travel silently through family systems, passed from body to body across generations — in both her professional practice and her own life.
Born in Switzerland and formed across Greece, the UK, Canada, and the United States, she came of age moving between worlds — learning early to read the codes of different cultures, different registers of power, different ways that people reveal and conceal what they most need. That fluency shapes everything she does.
That inheritance — personal and cultural — is the animating force behind her original clinical framework, PIAR (Predictive‑Interoceptive Attachment Repair), which integrates predictive processing, attachment research, and interoception science into a coherent model of how the body learns to feel safe enough to change.
She is the founder of One Sanctum, a retreat and gatherings organisation dedicated to the conditions under which genuine transformation becomes possible.
"One Sanctum is the fullest expression of everything I have come to know about what human beings need, and what becomes possible when they are given the conditions to find it."
