Drug and Alcohol Treatment for Montana

Rimrock is Eastern Montana’s largest alcohol and drug use treatment center, serving both adults and adolescents.

Rimrock is nestled in the healthcare corridor beneath the rims of Billings, Montana. Inpatient treatment offers needed separation from potential stumbling blocks to a person’s recovery. Yet it is convenient for patients to receive support from family and friends during the recovery process.
