Khashayar Nattagh, MD

I offer comprehensive clinical evaluations, consultations, and specialized treatment for individuals with OCD and related disorders. My approach is tailored to my patients’ needs, utilizing evidence-based psychotherapy—such as ERP and CBT—alongside medication management and advanced TMS (Transcranial Magnetic Stimulation).

I am a board-certified psychiatrist, researcher, and the Director of the Bridge OCD Program. I earned my medical degree from UCSF and completed my psychiatry residency at Harbor-UCLA Medical Center.

I specialized in OCD and related disorders at the UCLA Semel Institute for Neuroscience and Human Behavior. There, I trained in the adult OCD Intensive Outpatient Program, the Insomnia Clinic, and pediatric clinics for OCD, anxiety, and tic disorders. Currently, my research focuses on a clinical trial at USC investigating how to combine psychotherapy with TMS to improve patient outcomes.

I am committed to providing a safe, affirming, and welcoming space for people of all backgrounds. My practice is built on the principle of respect for all individuals, regardless of race, ethnicity, gender, sexual orientation, or religion. I believe that every person’s unique life experiences and cultural background are essential parts of their identity. My goal is to understand your story and provide care that is tailored to who you are as an individual.
