Leckey Harris - who is on LinkedIn - has a trauma-informed initiative for 'first responders' (it includes a technique known by the Acronym "TRE") .. I'll try to avail further info and particulars later.
The "On-Site Academy" in Gardner, Massachusetts has moved their [previously nation-wide First Responder] crisis/respite component to a nearby rural serene farm, with animals; now serves both 'First Responders' and 'Human Services Personnel' --previously nation-wide, now 'world-wide'; they had EMDR certified clinicians-I don't know the current status of that.
