Volunteer Manager

Christa Yeager |

Christa started with CASA of Berks County as a CASA volunteer in March 2016 and became a Volunteer Manager in August 2017. Born and raised in West Chester, PA, Christa moved to Berks County following graduation where she lives with her husband of 24 years. Christa is a mom of seven children and a grandmother of two grandchildren.

Over the years, Christa has been involved with her community through church outreach with a focus on children's ministry, holding positions as Nursery Supervisor and Sunday School Superintendent. Christa continues to teach elementary and middle school science for a local home school co-op.

As a volunteer, Christa became passionate for the program and for what it stands for, believing that every child facing abuse and neglect should have a CASA to help ensure their right to a safe and permanent home. She writes, "As a CASA you can impact a small part of a child's success and their future, something every child deserves."
