SHERMAN, Texas (KTEN)—The Grayson County chapter of Court Appointed Special Advocates for children is coming up on 30 years of helping the county's children.

CASA volunteers step in to help advocate for children removed from their homes due to abuse or neglect and help get them in a permanent and healthy environment.

"I think the most rewarding is being able to see a kid— child or a sibling group—either end up back at home with parents that are doing well and able to care for them in a way they should," Executive Director James Hamilton said. "And then also being able to see kids that are able to find their permanent home if its outside of their family."

Board member Marty Sanderson's sister, Jayne Gump was a driving force in the establishment of not just Grayson County's CASA, but of Texas's statewide CASA organization as well. After adopting a child who had been in a neglectful home, she realized that children in the foster system needed someone to stand up for them.

"That made her aware that we needed something to help these kids, because what happens?" Sanderson said. So she moved to Austin and started CASA there, and then realized they need to be everywhere. And so she was the first executive director of state CASA, and started helping get them across the state."

CASA is holding a celebration on Saturday, July 8 from 9 a.m. to 1 p.m.
