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.
