Advances in both military and medical technology have led to decreased mortality rates among military service personnel in the United States, yet have led to an increase in occurrences of traumatic brain injuries and posttraumatic stress disorder in military service personnel, often resulting in prolonged unresolved symptoms. The purpose of this article is to illustrate the implementation and effects of an art therapy program on military service personnel attending an outpatient military treatment facility. To this end, we present case reports of three military service personnel diagnosed with comorbid traumatic brain injury and post-traumatic stress and describe their participation in the art therapy program at Intrepid Spirit One, the National Intrepid Center of Excellence satellite site at Fort Belvoir Community Hospital. Through discussion of the therapist's subjective observations, as well as the patients' visual art productions and their personal verbal and written reflections on their experiences in art therapy and, eventually, on community art programs, this article highlights how art therapy was used to treat military trauma as part of a comprehensive integrative treatment program. The cases highlight how participation in a long-term, stage-based, structured art therapy program (through both group and individual sessions), enabled military service personnel to identify and articulate the complexity of their lingering trauma symptoms, fostering improvement in their communication with other treatment providers and loved ones, which, in turn, led to improvements in their overall quality of life.
