At the 2026 Facilitation Lab Summit, Trudy Townsend closed two days of deep work with a session that went straight at a topic every facilitator encounters but rarely names: trauma is already present in every room you enter, and it shapes how people show up, engage, and disengage. Drawing on the ACEs study, Dan Siegel's hand model of the brain, and years of practice, Trudy offered facilitators a grounded understanding of how the nervous system works, what dysregulation looks like in a group, and what it actually takes to create safety. Not a checklist, but a stance. A must-read for anyone committed to building spaces where participants can genuinely show up as their best selves.
