It takes a village to raise a foster child.

It takes a village to raise a child, and that is even more true of foster children with their complex challenges and needs. Contra Costa Foster Friend’s mission is to come alongside foster families in Contra Costa County and provide them with critical and ongoing support so that they are able to continue opening up their hearts and homes to foster children. We accomplish this by building relationships, meeting tangible needs and giving them a place to be encouraged, valued and connected.

He is married to Claudia and as he is now retired he is able to help manage their large family and assist in running Contra Costa Foster Friends. He has also been a devoted, loving foster parent for 16 years.

Julie Erwin


Julie's heart for foster children led her to become a CASA 12 years ago and she was able to mentor 2 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!
