About Me

Dr. Earth Hasassri, MD

Pronouns: he/his/him

I am a Volunteer Clinical Assistant Professor of Psychiatry at the University of California, San Francisco. 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.

Prior to medical school, I completed two undergraduate bachelor’s degrees in Physiology & Neuroscience and Psychology at the University of California, San Diego. As a child of immigrants from Thailand, I minored in Global Health by studying clinical epidemiology abroad while working with refugees through the United Nations in Jordan.

I attended medical school 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. Here, I developed an interest in child and adolescent mental health while evaluating and treating medically complex illnesses that caused seemingly irreparable harm on the identities of these children and the functioning in their family unit and school communities. However, I soon discovered that -50 degrees Fahrenheit Minnesota winters were much too cold for my liking and soon retreated back to a warmer California.

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. There, I joined the lab of Nolan Williams here to conduct research studies on applying transcranial magnetic stimulation to pediatric populations, such as those with Autism Spectrum Disorder or Major Depressive Disorder. My goal is to bring cutting edge interventional procedures to alleviate the suffering of those who have been failed by other forms of conventional treatment. Here, I trained in the psychotherapeutic modalities of cognitive behavioral therapy in children and adolescents with a special focus on functional neurological disorders such as psychogenic nonepileptic seizures, parent management training, psychodynamic play therapy, supportive parenting for anxious childhood emotions (SPACE), and comprehensive behavioral intervention for tics (CBIT) which includes habit reversal training.
