Into Independence:Watch Naomi's Story

Life after foster care can be hard in Sonoma County. Naomi, a former foster youth, spent years living in different transitional programs before finding the permanent housing and support she needed at Sanctuary House. Hear her story and see how Community Support Network, the nonprofit that operates Sanctuary House, is helping transitional age youth move into independence every day.

Because lives can be recovered after trauma.
