Mark Rybakov, DO is a psychiatry practice serving children, adolescents, and adults in Brooklyn and Manhattan, with care that spans the different stages and demands of life. The scope is notably broad, encompassing both general psychiatric treatment and focused attention to conditions that often require careful, ongoing management. A particular emphasis is placed on ADHD and bipolar disorder, two areas that call for thoughtful evaluation and steady clinical oversight. That combination of age-inclusive psychiatry and disorder-specific focus suggests a practice attuned both to developmental differences and to the distinct complexities of mood and attention-related conditions.
