Hi,
This post thread has a few resources: https://www.pacesconnection.com...trauma-informed-care. There is also a guide to create healthy, wellness centered meeting spaces.
Written self-care/collective care alerts around the room and within all the presentations serves as an intentional and helpful reminder for attendees. At a restorative justice summit we provided a space for people to make aromatherapy satchels and knit. And when we do not have a budget for all the great tools and toys at a minimum, I try to provide a quiet space with calming light. Lastly, I try to ensure the TI principles are prominent throughout the space and meeting process.
