Hi Adrienne,
At the Center for Health Care Strategies we work closely with the team at the San Francisco Department of Public Health (SFDPH) that is leading the department's Trauma-Informed Systems initiative. We actually have a national webinar coming up that will feature the work of SFDPH that might be of interest to you and your colleagues. More information about the webinar and how to register can be found here.
In addition, SAMHSA recently released a profile on SFDPH's work. You can find that profile here.
Thanks!
