John Cahill, MD, PhD

Dr. Cahill serves as Residency Program Director for the Yale Department of Psychiatry. As Chief of Behavioral Health at Continuum of Care Inc. he helped build the first co-occurring disorders residential treatment center, community-engaged crisis response team (Elm City COMPASS) and crisis receiving center (REST) in Connecticut. He has been instrumental in the adaptation and promotion of the construct of 'deprescribing' in psychiatry: as a means to seek minimum-effective dosing of medications; to center the patient; to deepen a shared formulation; and to fully integrate psychodynamic and socio-cultural considerations.

John is interested in emerging severe mental illness; continuous quality improvement via multi-stakeholder driven Learning Health Systems and translational research approaches. He co-created and directs the HONE (Healthcare Outcomes Network & Education) software consortium for first episode psychosis care, implemented in dozens of clinics nationally.

He undertook medical school and PhD training in the UK and completed psychiatry residency and clinical research fellowships at Yale. He is board certified in Psychiatry, Addiction Medicine and Clinical Informatics.
