About

Earth Hasassri, M.D.

Pronouns: he/his/him

I am a California-Licensed physician, dual board-certified in Psychiatry and Child and Adolescent Psychiatry 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 serve as an Adjunct Clinical Assistant Professor of Psychiatry at Stanford University School of Medicine, where I teach and mentor the next generation of physicians. I maintain a private practice in Menlo Park, California, where I provide individualized psychiatric care to children, adolescents, and adults.

My approach to psychiatry is grounded in the belief that effective mental healthcare requires understanding the whole person, not simply treating a collection of symptoms. I integrate psychotherapy, psychopharmacology, and advances in clinical neuroscience to develop thoughtful, evidence-based treatment plans tailored to each individual’s needs, circumstances, and goals.

I have a particular interest in complex psychiatric and neurodevelopmental conditions, treatment-resistant illness, and emerging approaches in interventional psychiatry and neuromodulation, including transcranial magnetic stimulation (TMS). My goal is to bring together the depth of a therapeutic relationship with the scientific advances that are expanding what is possible in psychiatric treatment.

My Clinical Practice

In my private practice, I work with children, adolescents, and adults across a broad range of psychiatric conditions, including ADHD, autism spectrum disorder, anxiety, depression, obsessive-compulsive disorder (OCD), and complex neuropsychiatric presentations.

I particularly enjoy working with patients and families facing complicated diagnostic or treatment questions, including individuals who have not responded as expected to previous treatments. I believe that careful assessment, a strong therapeutic relationship, and a willingness to revisit diagnoses and treatment approaches when patients are not improving are essential to effective psychiatric care.

Living and practicing in Silicon Valley has also given me an appreciation for the unique pressures faced by individuals and families in the Bay Area. I work with founders, executives, entrepreneurs, and professionals navigating demanding careers, as well as parents balancing work, relationships, and raising young children.

I also work with gifted and high-achieving adolescents facing academic pressure, perfectionism, anxiety, and burnout. My approach emphasizes not only reducing distress but helping patients develop resilience, self-understanding, and a sense of fulfillment that extends beyond achievement or external expectations.

Across all ages, I strive to provide care that is collaborative, compassionate, and grounded in both scientific evidence and an understanding of each person’s lived experience.

Education and Clinical Training

My interest in understanding the relationship between the brain, behavior, and human experience began at the University of California, San Diego, where I earned dual bachelor’s degrees in Physiology & Neuroscience (B.S.) and Psychology (B.A.), along with a minor in Global Health. I became fascinated by how processes at the molecular and neural levels influence individual behavior, relationships, and ultimately the broader social and cultural environments in which we live.

I subsequently earned my medical degree from the Mayo Clinic Alix School of Medicine in Rochester, Minnesota. Mayo Clinic’s guiding principle that the needs of the patient come first continues to shape my philosophy of medical care and my commitment to putting patients and families at the center of treatment decisions.

I completed my Psychiatry Residency training at the University of California, San Francisco, where I earned an Area of Distinction in Clinical Neuroscience for applying neuroscientific principles to psychiatric care. My training included extensive experience in psychopharmacology and multiple forms of psychotherapy, including cognitive behavioral therapy (CBT), interpersonal therapy (IPT), emotionally focused therapy (EFT), cognitive processing therapy (CPT), and psychodynamic psychotherapy. I completed the Psychoanalytic Psychotherapy Foundations Training Program at the San Francisco Center for Psychoanalysis. Following residency, I served as a Volunteer Clinical Assistant Professor at UCSF, teaching medical students, residents, and fellows.

I then completed subspecialty fellowship training in Child and Adolescent Psychiatry at Stanford University School of Medicine, where I developed additional expertise in the evaluation and treatment of children and adolescents with complex psychiatric and neurodevelopmental conditions.

My fellowship training included cognitive behavioral therapy for children and adolescents, parent management training (PMT), psychodynamic play therapy, Supportive Parenting for Anxious Childhood Emotions (SPACE), and Comprehensive Behavioral Intervention for Tics (CBIT). I also received specialized training in functional neurological disorders, including psychogenic nonepileptic seizures, and in the assessment and treatment of autism spectrum disorder through the Stanford Autism Clinic. I completed training in the administration of the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) a widely used standardized observational assessment for autism.

These experiences inform my integrative approach to psychiatric care, allowing me to draw from multiple therapeutic traditions while considering each patient’s developmental, psychological, biological, and family context.

Clinical Neuroscience, Research, and Neuromodulation

Throughout my medical training and career, I have maintained a strong interest in the intersection of neuroscience and clinical psychiatry, particularly in translating scientific discoveries into meaningful improvements in patient care.

During my fellowship at Stanford, my scholarly work included research on TMS, the safety of neuromodulation in children and adolescents, pediatric catatonia, adolescent ketamine treatment, and novel treatments for autism spectrum disorders. I have contributed to clinical research and published in peer-reviewed journals including The American Journal of Psychiatry, Academic Pediatrics, Psychosomatics, and Pediatrics in Review.

I have also presented my work at professional conferences and academic institutions, including the American Academy of Child and Adolescent Psychiatry, Northern California Psychiatric Society, Mayo Clinic, UCSF, and Stanford.

Building on my background in clinical neuroscience, I have expanded my clinical work into interventional psychiatry and neuromodulation, including TMS. I am particularly interested in accelerated TMS protocols, neuroimaging-informed targeting, and personalized, circuit-based approaches to treating psychiatric conditions that have not responded adequately to conventional therapies. I am also interested in the emerging applications of neuromodulation in child and adolescent psychiatry, where ongoing research may expand treatment options for young people with complex and treatment-resistant conditions.

I believe the future of psychiatry lies not in choosing between psychotherapy, medications, and neuroscience-based interventions, but in thoughtfully integrating these approaches to provide more effective and individualized care.

Outside the Office

Outside of my clinical work, I enjoy spending time with my wife and our two young children, exploring Bay Area parks and trails, cooking and discovering new cuisines, and playing golf as I work on improving my handicap.

Living in the heart of Silicon Valley, I also enjoy following developments in technology, artificial intelligence, and neuroscience, particularly their potential to improve healthcare and the human experience.

In addition to English, I provide psychiatric care in Thai.
