Dr. Earth Hasassri, MD

Pronouns: he/his/him

I am a licensed physician in California and double board-certified as a Psychiatrist and Child and Adolescent Psychiatrist by the American Board of Psychiatry and Neurology. I completed a Child & Adolescent Psychiatry fellowship at Stanford University and my Adult Psychiatry residency at UCSF. I am a Volunteer Clinical Assistant Professor of Psychiatry at the University of California, San Francisco.

Prior to medical school, I completed two undergraduate bachelor’s degrees in Physiology & Neuroscience (B.S.) and Psychology (B.A.) at the University of California, San Diego with a minor in Global Health. I studied both the micro- and macro-level components of what goes into a person’s experience and behavior, from the cellular level to the individual to the cultural and societal factors.

I attended medical school (M.D.) at the Mayo Clinic Alix School of Medicine, the number one ranked hospital according to US News & World Report for more than 30 years and a top-ten ranked medical school. Because people with complex illnesses travel to the Mayo Clinic from all over the world, I learned how to evaluate and treat both simple and medically complex illnesses from world class physicians who were not only outstanding clinicians, but dedicated educators and thoughtful researchers.

I then completed my Psychiatry Residency at the University of California, San Francisco where I was awarded an area of distinction in clinical neuroscience for my clinical work at applying neuroscientific principles into clinical practice between the interface of psychiatry and neurology. My psychotherapy training here included cognitive behavioral therapy, interpersonal therapy, emotionally focused therapy for couples and families, cognitive processing therapy for trauma, and psychodynamic psychotherapy. I sought deeper training in psychotherapy at the San Francisco Center for Psychoanalysis where I completed the Foundations of Psychoanalytic Psychotherapy Training Program. 

After finishing residency, I pursued subspecialty fellowship training at Stanford University in Child and Adolescent Psychiatry. Here, I trained in the psychotherapeutic modalities of cognitive behavioral therapy (CBT) in children and adolescents with a special focus on functional neurological disorders such as psychogenic nonepileptic seizures, parent management training (PMT), psychodynamic play therapy, supportive parenting for anxious childhood emotions (SPACE), and comprehensive behavioral intervention for tics (CBIT) which includes habit reversal training (HRT).

Training Matters

When you engage with the healthcare system, it’s important for you to understand the qualifications of the professionals providing your care. While both physicians and mid-level providers like nurse practitioners play crucial roles in healthcare, their training and expertise differ in meaningful ways. To clarify these distinctions, here’s a comparison chart that outlines the differences in education and training between a physician and a nurse practitioner within the same specialty of Child, Adolescent, and Adult Psychiatry.
