Our Gatherings

The work, in place.

One Sanctum gathers a small number of remarkable people — in places that hold something of their own — for multi-day immersions into what it means to remain whole, and fully alive, in a fragmenting world.

Our inaugural gathering, five days on the island of Spetses with Dr. Gabor Maté, was held to capacity in May 2026. New gatherings are now forming.

Spetses · May 2027 Recovering Our World Save the Date
One Sanctum was founded on the belief that

the most important conversations of our time are not happening at scale — they are happening in rooms, between people who have found each other at the right moment. We build those rooms.

One Sanctum is built for those who are ready to stop filling the space — and to find out what has been waiting there. 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. Each retreat is a progression, not a programme. The intellectual and the somatic interweave. The group itself becomes a resource.

Put the right people together in the right conditions, and something happens that none of them could have produced alone.
