Cascade Behavioral Health Staff

Dr. Aaron Andersen

Chief Medical Officer

Dr. Andersen has devoted his career to providing quality patient care in both clinical and leadership settings since 2008.

He began his clinical training as a doctoral student in clinical neuropsychology at Utah State University in 2005. During this period, he received training in neuropsychological testing, psychotherapy, and research. During his graduate training, he did research for the Cache County Study on Memory and Aging. He was also involved in research utilizing MRI for examining neurobiological correlates of depression.

Due to his growing interest in medicine, Dr. Andersen decided to leave his doctoral program and pursue a medical career in 2008; and he began medical studies that year at Des Moines University College of Osteopathic Medicine. He also joined the U.S. Army Reserves as a medical corps officer in 2007. Upon graduation from medical school in 2012, he began active duty as an Army medical officer. In 2013, following completion of his internship at Darnall Army Medical Center in Ft. Hood, TX, he began a psychiatry residency at Walter Reed National Military Medical Center in Bethesda, MD, where he treated behavioral health conditions in active duty and retired service members and their families in the Army, Air Force, Navy, Marines, and Coast Guard.

After completion of his psychiatry residency in 2016, he spent his first year working as an outpatient psychiatrist and assistant clinic chief in a hospital clinic at Ft. Campbell, KY, treating members of the Combat Air Brigade. During this brief period, his clinic was recognized for having the highest behavioral health patient satisfaction scores in the U.S. Army, a recognition never before achieved by a behavioral health clinic at Ft. Campbell.

Following his work at the CAB, Dr. Andersen was promoted to medical director and chief of inpatient psychiatry in 2018. In that role, he helped to oversee the opening of a new inpatient psychiatry unit at Blanchfield Army Community Hospital, while simultaneously supervising behavioral health clinicians in the emergency room as well as the consult-liaison psychiatry service.

After completion of his military service in 2020, Dr. Andersen worked as an outpatient psychiatrist for Trinity Health Systems, and later that year took a temporary position at the University of Washington Northwest Hospital in Seattle, WA, working on the inpatient geropsychiatry unit and the consult-liaison psychiatry service. In April 2021, Dr. Andersen accepted a position with Cascade Behavioral Hospital as Chief Medical Officer.

As a military-trained psychiatrist, Dr. Andersen has special expertise in treating PTSD and traumatic brain injury. He also has expertise in diagnosing and treating adults on the Autism Spectrum and adults with ADHD. In recent years, he has done additional study to broaden his clinical skills, which has included training in the use of TMS and the use of SPECT neuroimaging for guiding psychiatric treatment in clinical settings.
