Strategies: The SOC expands trauma and grief informed care, cultural and linguistically responsive evidence-based mental health services, suicide prevention and intervention, policy development with a co-serving network of agencies strengthening transitional planning, integrated mental health treatment with cross-agency care coordination coupled with wraparound recovery support services with linkages to vocational counseling, education services, primary healthcare, dental, substance abuse prevention, stable housing, including independent living. Each participant will work with a care team that facilitates the identification and implementation of an individualized service plan in partnership with the child/youth, family, supports to achieve their personal goals. The SOC expansion will include family/youth peer support, family and youth leadership development, mentoring, and youth-guided activities. Goals: 1) Expand, integrate and sustain the SOC improving access, infrastructure and sustainable financing while ensuring a flexible, innovative CQI approach, cross-agency collaboration, implementing trauma/grief informed care; 2) Meaningfully involve children, youth and young adult consumers and family/caregivers in their own care and the broader governance of the SOC; 3) Facilitate a network of co-serving providers wrapped around the system of care who use trauma and grief-informed care, evidence-based practices and programs to assess, screen, treat, and manage mental health, including suicide risk; 4) Improve mental health functioning, embedding evidence-based and evidence-informed services and supports in early childhood, youth and young adult intervention services and mental health disorders treatment; 5) Improve health equity with targeted outreach in underserved communities to engage racial, ethnic and LGBTQI+ minorities into SOC services.
