Another thought, in regard specifically to bringing in trainers or speakers. You may try - if you have them - your local domestic violence shelter, rape crisis center, or other victim advocacy organization. Oftentimes these agencies are already utilizing a trauma-informed model and may be of some help in that regard. I actually work for a DV agency and we provide trauma-related trainings to our local service providers, schools, community members, etc. And in Pennsylvania, all DV and rape crisis services must be provided at no cost, including community education. I don't know where you are located, but that may hold true for your location as well.
