NORMAN — Stephanie Clark was happy to return Thursday to the Children’s Recovery Center of Oklahoma. So much had changed for both in only nine months. For one, the facility was called the Norman Adolescent Center when Clark arrived in March. The newly named Children’s Recovery Center, 320 12th Ave. NE, combines the old Norman Adolescent Center and the Oklahoma Youth Center. Clark, 17, said she has been drug-free since being sent to Norman for in-patient treatment after she was caught smoking marijuana at her then-foster parents’ house. She also met her current foster parents, Steve Rogers and Kat Roberts, while at the Children’s Recovery Center of Oklahoma. "Kids think, ‘I don’t have a problem,’ and I was like that, too,” she said. "If I didn’t come here, I probably would have got worse.” The center works with children ages 5 to 17 dealing with mental illness or substance abuse.
