Contra Costa Foster Friends

​​​​Contra Costa Foster Friends provides critical and ongoing support to foster children and their caregivers in Contra Costa County.  The heart of our operation is our Resource Center, a brick and mortar “store” located in Pleasant Hill full of essential items for local youth in care, all at no charge to them. Foster children often arrive with only an hour or two notice and with only the clothes they are wearing. It is our sincere desire that these precious youth are well provided for during their time in care. We rely on donations from the community to keep our center stocked and are so grateful for donations of new or excellent condition items.

Julie Erwin


Julie's heart for foster children led her to become a CASA 12 years ago and she was able to mentor two children through this program. It was such a memorable experience for her. After serving as a CASA she felt called to love on and support foster families and began a Foster/Adopt Ministry at her church. Just a short time later she met Claudia and the two combined their passion and together built Contra Costa Foster Friends. Julie is excited to continue the wonderful world of supporting foster families!
