Have you been let down by the mental health system? If you've been rushed through appointments, given quick diagnoses, or told your labs are "fine" when you know something is off, I want you to know you're not alone—and you're in the right place. As a psychiatric nurse practitioner, I created my practice for individuals like you who are ready to move beyond symptom-chasing and find a clear, root-cause understanding of their mental health.
As a board-certified Psychiatric Mental Health Nurse Practitioner, I provide comprehensive psychiatric evaluation and medication management for children, adolescents, and adults. I specialize in treating ADHD, anxiety disorders, depression, bipolar disorder, sleep disorders, and trauma-related conditions. My approach is practical, collaborative, and grounded in current evidence.
