Mia guides our case managers to assist the clinical team with psychosocial aspects of patient care and discharge planning. She brings practical experience in health care having spent 32 years in nursing, mostly in critical care and home care services. Mia has been with our hospital since it opened in 2008.

Mia can’t remember a time that she didn’t want to be a nurse. One of the most impactful professional experiences she’s ever had has been at our hospital. A young man had suffered sudden cardiac arrest and resuscitation efforts were delayed for more than seven minutes. He was flown to a local hospital where he wasn’t progressing neurologically. His father wanted everything possible done for his son, and he was brought to Advanced Care Hospital of Montana. Within 24 hours, he started waking up. After nearly two months here and then to an inpatient rehabilitation facility, he was able to go back to school in year. “People ask what we do differently,” Mia says. “I tell them that it’s the environment and our ability to spend more time with everyone.”

Mia obtained a bachelor’s degree in nursing from Minot State University in Minot, N.D.

In her spare time, Mia enjoys nature, golfing, swimming, and riding bicycles. She has been married for 27 years and has a daughter who is also pursuing a nursing career. She and her family enjoy the outdoors and traveling. They also raise Labrador puppies.
