Welcome to Rimrock Foundation

We offer hope and empowerment to overcome the chaos of addiction through compassionate, whole person care. Rimrock Foundation is where new beginnings start every day!

Inpatient Addiction Treatment is the cornerstone in the treatment of, and success in recovering from, addictions and co-occurring disorders. Rimrock Foundation in Billings, Montana, initiated the use of the integrated treatment model and we continue to lead the field of addiction treatment providers. We set the standard for alcohol and drug addiction inpatient treatment. Providing top quality outpatient and aftercare services, we are consistently breaking new ground by crafting innovative and new successful addiction treatment programs to assist people who suffer from compulsive and addictive behaviors.
