Dr. Fleisher graduated from Harvard Medical School and then completed both residency and fellowship training at the UCLA Semel Institute for Neuroscience/Resnick Neuropsychiatric Hospital. After fellowship, Dr. Fleisher joined the faculty of Harvard Medical School with a position at McLean Hospital, one of the most prestigious psychiatric institutions in the world. There he worked primarily with adolescents from around the country who were struggling with severe anxiety. In addition, he volunteered time as a peer supervisor in the adult clinic for Mentalization-Based Therapy for Borderline Personality Disorder (BPD).
Dr. Fleisher returned to UCLA to help grow and strengthen the clinical program, particularly for people struggling with BPD. He also maintains a private practice in Beverly Hills.
Dr. Fleisher's approach is grounded in developing a thorough understanding of the clinical problem at each level of analysis: biological, psychological, behavioral or functional, and systemic (including the family, the school, the neighborhood, etc.). From this understanding, he works with parents and patients to create an evidence-based, conservative treatment plan with clear and measurable goals for improvement. Dr. Fleisher has a long-standing interest in teaching at all levels of general and medical education, from mentoring middle-school students to training the child psychiatrists of tomorrow.
Dr. Fleisher has a particular interest in borderline personality disorder (BPD) in both adolescents and adults. He is certified by the Anna Freud Center in London as a supervisor for a type of psychotherapy called mentalization-based therapy or MBT. Dr. Fleisher teaches this approach with staff and trainees at UCLA as well as nationally.
