AAC Holdings Inc. said today it opened Laguna Treatment Hospital in Aliso Viejo.

Brentwood, Tenn.-based AAC provides inpatient substance abuse treatment for drug and alcohol addiction, and co-occurring mental and behavioral health issues.

Laguna Treatment Hospital is on Pacific Park Drive. It has 93 beds and is one of eight chemical dependency recovery hospitals in California, according to AAC.

AAC bought Laguna Treatment Hospital’s building for $13.5 million in 2015. The facility license at the time allowed 84 beds; AAC said then it planned to add up to 40 beds.

The building previously housed Arcadian at Aliso, an assisted living and memory-care facility.
