Philosophy of Care
I believe in helping people with serious mental illness recover to the best of their abilities in the least restrictive environment possible.
Dr. Barnhorst is an inpatient and emergency psychiatrist who provides care to patients with serious mental illness in the emergency department, the county jail, and an inpatient psychiatric setting.
Dr. Barnhorst is the Vice Chair for Community Mental Health at the UC Davis Department of Psychiatry, an Associate Professor in the Department of Emergency Medicine, and the Director of the BulletPoints Project, a state-funded effort to develop a firearm violence prevention curriculum for healthcare providers. In her clinical work, she treats patients with serious mental illness in serious mental illness in the Emergency Department, the county jail, a crisis unit and a 50-bed inpatient psychiatric hospital. She’s a nationally recognized expert on firearms law and mental illness, and her academic work focuses on the interface between firearms, violence, suicide and the mental health system. She has testified before the California and Alaska Senates on these issues, and writes about them for the New York Times, Slate, and her blog at Psychology Today.
