(Memphis) For two decades, the Memphis Child Advocacy Center has been working to help child victims and help prosecute abusers and sex offenders.

It’s now celebrating twenty years here in the Mid-South.

“In those 20 years, we have served lots and lots, thousands of children,” said Executive Director Nancy Williams.

Williams said in the last two decades children who’ve become victims of sex crimes have been able to tell their story in a kinder environment at the center, “Before we were here, children would go to 201 Poplar.”

The center serves as a friendly place where children can help with the investigation and also get the support they need.

Williams say the center also has another mission, “We are all about getting the word out that child sexual abuse can be prevented.”

“We see clear signs every day,” a public service announcement says.

The center recently launched a PSA to spread the word that the center also provides education.

“It’s an interactive three hour training,” said Williams. “We have trained, so far, five thousand adults.”

The course is called “Stewards of Children” and it teaches how to prevent child sex abuse.

With the Penn State Sandusky sex scandal in recent memory, University of Memphis’ Men’s Basketball Coach Josh Pastner has come forward as the course’s spokesman.

“Do what I did and learn how to spot it, prevent it and stop it,” said Pastner in the PSA.

The center hopes to train 3,500 more people in the next few years, making Memphis a safer place for children.

“We are excited about our history and we are more excited about the ways we are going to protect children in the next twenty years,” said Williams.
