Therapeutic Community Elders & the PETT Archive (Planned Environment Therapy Trust)
Episode summary: In this conversation, David Jones and Naomi Murphy are joined by Tom Harrison, Sarah Paget, Vicky Gavin, and David Kennard.. Together they explore what the Therapeutic Community (TC) Elders are, why their monthly open forums matter, and what it means for the field that the PETT archive at Toddington is closing. The group reflects on sustaining therapeutic community ideas, making knowledge accessible through a “living archive” (including Vicky’s A–Z artwork concept), and how people can get involved.

In this episode
Where the idea of the TC Elders came from and what the group is for.
Why the monthly Zoom Open Forums have become a key way of staying connected across countries and services.
How the Elders aim to hold a space for thinking, including “negative capability” (the capacity to sit with not knowing).
Who the Open Forums are for (not only people in formal therapeutic communities), and what people get from attending.
The story and purpose of the PETT archive—and what is being lost (and potentially preserved) as it closes.
A “living archive” approach: Vicky’s A–Z artwork as a way to invite memories, reflections, and contributions from the wider community.

Key takeaways
The TC Elders are less about “giving answers” and more about holding a reflective space for practitioners and communities.
The Open Forums function as a predictable monthly “anchor” that supports people doing relational work in challenging contexts.
The PETT archive represents a major collective memory of therapeutic community practice; its closure highlights the real costs of preserving history.
“Living archive” approaches (like the A–Z concept) may help capture stories, artefacts, and learning that don’t always make it into formal publications.
