Dr. Jonathan Tamaiev is a board-certified adult psychiatrist with advanced fellowship training in child and adolescent psychiatry. His practice is built on thoughtful evaluation, clinical expertise, and individualized treatment that places each patient’s unique needs at the center of care.
I am a board-certified adult psychiatrist with advanced fellowship training in child and adolescent psychiatry. I work with children, adolescents, adults, and families across a wide range of psychiatric concerns, from diagnostic uncertainty and difficulties with everyday functioning to complex and acute psychiatric illness.
I completed my psychiatry residency at SUNY Downstate Health Sciences University and my child and adolescent psychiatry fellowship at Northwell Health/Long Island Jewish Medical Center. I also completed a two-year psychodynamic psychotherapy training program through the Psychoanalytic Institute of New York at NYU. My broader background includes medical training at the Technion–Israel Institute of Technology and undergraduate study in psychology, behavioral neuroscience, and philosophy at Hunter College.
I believe that good psychiatry requires time, judgment, and clinical seriousness.
Symptoms rarely exist in isolation. To understand what is happening, it is often necessary to consider a person’s development, relationships, family, culture, school or professional life, medical history, and individual goals. A diagnosis can be useful, but it should not replace a thoughtful understanding of the person experiencing it.
My approach is neither reflexively pro-medication nor anti-medication. Medication can be enormously helpful when it is appropriately selected and carefully managed, but it is only one part of psychiatric care. Treatment may also involve psychotherapy, diagnostic clarification, collaboration with therapists or physicians, work with parents and families, and attention to the patterns and circumstances shaping a person’s life.
I aim to be clear, collaborative, and direct with patients. That includes explaining how I understand the problem, acknowledging uncertainty when it exists, and making treatment decisions together rather than reducing care to a series of brief medication adjustments.
My work has included private outpatient practice, psychiatric emergency care, community mental health, medical leadership, teaching, and research. I have treated patients in academic hospitals, community clinics, emergency departments, inpatient units, and private-practice settings.
Working across these environments has shaped how I practice. Emergency psychiatry taught me how to remain calm and make careful decisions when the stakes are high. Long-term outpatient work taught me the importance of continuity, trust, and understanding how symptoms evolve over time. My psychotherapy training reinforced the value of listening closely and looking beyond the most immediate complaint.
Today, my clinical work is centered at Highline Psychiatry, the practice I founded to provide thoughtful, physician-led psychiatric care in a setting designed around the needs of patients rather than the limitations of a large institution.
