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. Niendam is a licensed clinical psychologist with specialized training in assessment and treatment for youth at risk for or in the early stages of psychosis. As the Executive Director of the UCD Early Psychosis Programs, Dr. Niendam supervises clinic activities and staff and coordinates outreach and educational presentations within the community.

She also serves as the Co-Director for our pre-doctoral Trauma and Adolescent Mental Illness (TAMI) internship, which is a collaboration with the UC Davis CAARE Center, to provide evidence-based trauma informed care to youth with early psychosis.

Research/Academic Interests

Dr. Niendam's research seeks to improve clinical and functional outcomes for youth with serious mental illness. Her research has focused on four key themes: 1) Elucidating factors that contribute to real world functioning and clinical outcome across psychiatric disorders, 2) Evaluating the impact of interventions on outcomes in psychosis and other mental health diagnoses, 3) Developing technology-enhanced methods to improve identification and enhance treatment, and 4) Enhancement and dissemination of best practices for early psychosis care.  She has explored these themes within and between multiple specific disorders, across dimensions of clinical symptomatology, and investigated how they can be impacted by intervention. Taken together, Dr. Niendam strives to improve long-term clinical and psychosocial outcomes for youth with serious mental illness.
