Philosophy of Care

Dr. Niendam supports all clients toward wellness and recovery, believing that managing symptoms is secondary to having meaningful roles, goals and relationships in one's life. She also believes that family and support persons are important for the recovery process and strives to include them in all aspects of assessment and treatment.

Clinical Interests

Dr. Tara Niendam is a licensed clinical psychologist and a Professor in the UC Davis Department of Psychiatry. As the Executive Director of the UC Davis Early Psychosis Programs (EDAPT and SacEDAPT Clinics), Dr. Niendam supervises clinic and training activities, and coordinates outreach and educational presentations within Sacramento and across California. She has developed 5 early psychosis programs in Northern California based on the coordinated specialty care model of early psychosis, sharing expertise on the course of early psychotic illness, evidenced based treatments for psychosis, and the use of standardized clinical assessments of early psychosis symptoms, functioning, and outcomes.

Research/Academic Interests

With funding from the Robert Wood Johnson Foundation, California Mental Health Service Oversight and Accountability Commission, California Department of Healthcare Services, and National Institutes of Mental Health, Dr. Niendam’s research uses mobile health technology to enhance early identification and treatment of youth and young adults with serious mental illness, with a focus on improving clinical and functional outcomes. The new EPI-CAL project, led by Dr. Niendam in partnership with UC San Francisco, UC San Diego, University of Calgary, The One Mind ASPIRe program, and multiple California counties, will bring client-level data to the clinician’s fingertips, and enable large scale data-driven approaches to improve outcomes for EP care. She also directs the EPI-CAL affiliated Training and Technical Assistance Center, which seeks to bring evidence based early psychosis care to all Californians.
