Dr. Reinhart’s practice is influenced by his training and research in political and medical anthropology, psychoanalysis, and social psychiatry. He views mental health as inseparable from history, culture, and social context––not just neurobiology. His approach ensures patients time to elaborate how their life history shapes their experiences and goals. In a healthcare system that often relies on generic diagnoses and standardized plans, Dr. Reinhart works with each patient on their own terms, integrating psychotherapy and potential medications to support the pursuit of their unique life possibilities.

Dr. Reinhart often works with writers, actors, musicians, and visual artists and with journalists, academics, athletes, healthcare workers, and activists, many of whom seek treatment in response to creative blocks, burnout, and relationship struggles. He also has long-term experience working with people who have lived through incarceration, war, torture, migration, childhood abuse, and psychosis, and with those building queer and trans identities and communities.

To facilitate durable changes, Dr. Reinhart regards psychiatric symptoms as matters to be taken seriously, understood, and worked through, not simply suppressed by medications. He asks patients to actively engage in treatment and often recommends frequent appointments to support this.
