She’s passionate about tackling complex issues—suicide prevention, C-PTSD, chronic depression, ASD, OCD—and advocating for underserved communities. For Holly, it’s about delivering real, meaningful support to those who need it most.

Her career began as a registered nurse in neurology, pediatrics, and emergency care, before she found her calling in psychiatry. Since then, she’s provided medication management and supportive psychotherapy in outpatient clinics and worked in inpatient units serving adults and adolescents.

Holly believes in patient-centered care based on the individual, rather than focusing only on a diagnostic algorithm. The first appointment will include a comprehensive psychiatric evaluation and a discussion about what your goals of treatment are. Pharmacological and therapeutic recommendations are both important elements of the treatment plan. Follow up appointments will be more concise, but may include various therapeutic modalities, medication changes, and supportive psychotherapy.
