Greg Hard is a board-certified psychiatric nurse practitioner who provides compassionate, collaborative and evidence-based psychiatric care to children, adolescents, and adults. He specializes in the treatment of ADHD, including adult and late-diagnosed ADHD, as well as OCD, depression, anxiety, and bipolar disorder. In the pediatric population, Greg specializes in ADHD as well as disruptive behavioral and mood disorders including oppositional defiant disorder (ODD) and disruptive mood dysregulation disorder (DMDD).
Greg understands how frustrating it can be to feel unheard or to try multiple treatments without lasting relief. His practice is grounded in a patient-centered approach that emphasizes collaboration, trust, and individualized care. He draws on a broad range of tools to help patients achieve meaningful improvement, including evidence-based medication management, targeted psychotherapy strategies, precision psychiatry, and emerging and holistic treatments when appropriate.
Greg completed his Master of Health Science degree at Johns Hopkins University and his Master of Science degree at the MGH Institute of Health Professions. Greg received advanced clinical training at Massachusetts General Hospital in Boston, where he worked extensively with both adult and adolescent patients across a wide range of psychiatric conditions. His clinical style blends scientific rigor with empathy, creating a supportive space where patients feel both seen and empowered.
Greg believes that good psychiatric care goes beyond diagnosis and medication—it’s about understanding the full person, identifying root causes, and building a treatment plan that reflects each individual’s unique goals and values. Whether addressing complex mood disorders, treatment-resistant symptoms, or helping patients better understand and manage their neurodivergence, Greg is committed to helping each person find a clearer path forward.
