Holy Rosary Hospital is a comprehensive acute-care hospital in Miles City that serves an 11-county region of eastern Montana. It includes physician clinics, a residential living community, hospice and palliative care services. Holy Rosary is part of the Intermountain Health system. Based in Utah with locations in seven states (Montana, Colorado, Idaho, Kansas, Nevada, Utah, and Wyoming) and additional operations across the western U.S., Intermountain Health is a nonprofit healthcare system comprised of 33 hospitals, 385 clinics, medical groups with some 3,800 employed physicians and advanced practice providers. To help people live the healthiest lives possible, Intermountain is committed to improving community health and is widely recognized as a leader in transforming healthcare by using evidence-based best practices to deliver high-quality outcomes at sustainable costs consistently.

Holy Rosary Healthcare has a century-long commitment to the people of eastern Montana. Our legacy began August 15, 1910, when the Presentation Sisters assumed management and later purchased the County Hospital in Miles City, renaming it Holy Rosary Hospital. Through the years, the hospital continued to grow and evolve.

In 1995, a modern health facility was built on a unified campus with total healthcare services available in a single location. SCL Health became the sole owner in 1997, purchasing Holy Rosary Healthcare as an integral part of a growing, faith-based, nonprofit healthcare system. SCL Health was established 150 years ago by the Sisters of Charity, and today operates 11 hospitals, three safety-net clinics, one mental health treatment center for children and more than 210 ambulatory practices in three states. Other Montana care sites within SCL Health are St. Vincent Healthcare in Billings and St. James Healthcare in Butte.

As a care site of SCL Health, Holy Rosary has direct access to best practices in healthcare delivery, resources, technology, talent and strategic capital. Together, the physicians, providers, associates and volunteers of Holy Rosary Healthcare extend God’s healing love in the tradition of the Presentation Sisters and the Sisters of Charity and our own rich history of providing care in eastern Montana.

In 2022, SCL Health merged with Intermountain Health becoming a 60,000+ person strong nonprofit health system, with operations in seven states across the interior west with a shared vision to be a model health system that inspires the future of health.
