Since 1968, Rimrock has created opportunities for those impacted by addiction and mental illness through innovative, compassionate and life-changing care.

As the largest treatment provider in the Rocky Mountain West for substance use disorders (SUDs) and mental illness, Rimrock cares for the whole person and makes recovery possible. Last year alone, Rimrock helped nearly two thousand people find their way out of addiction, providing a path to a brighter future.

Rimrock provides life-changing care to our clients — care that addresses their unique social, physical, emotional and spiritual well-being. So much is changing in our world, and Rimrock continues to grow and evolve to meet the moment and our clients’ needs.
When people come to Rimrock seeking help, they are often at the lowest point of their lives, facing the loss of relationships, employment, housing or even their freedom as a result of their addiction.

Please join us in our Capital Campaign by making a donation today.

Your dollars will go directly to building our new 5-acre campus in the eastern part of downtown Billings.


The new campus will provide a continuum of care for those experiencing substance use disorders and mental health challenges.
