Communities of Practice

Trauma-Informed Systems (TIS)


Using implementation science for county and regional system change

We believe that this transformation—from systems that induce trauma to systems that can sustain healing practices and wellness—occurs along a continuum from Trauma Organized (systems so impacted by organizational stress and trauma that they present symptoms similar to those of individuals impacted by trauma) to Healing Organizations and Systems of Care.

This is an organizational change model aimed to create contexts that nurture and sustain trauma-informed practices and to create organizations, agencies and schools that reduce trauma.

About TIS

TIS is an organizational change model developed by San Francisco Department of Public Health to create context that nurture and sustain trauma-informed practices. 

“Trauma Informed Systems principles and practices support reflection in place of reaction, curiosity in lieu of numbing, self-care instead of self-sacrifice and collective impact rather than silo-ed structures.” 
-Epstein, K | Speziale, K | Gerber, E | Loomis, B (2014)
