I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) licensed in WA, NY, NM, and AZ. With 18 years of dedicated experience in psychiatry, I bring a unique, deeply grounded perspective to your care. I’ve spent nearly two decades sitting with clients, listening to their stories, and watching what treatments truly work in real life.

I believe every person deserves to be heard, understood, and treated with dignity. My approach is holistic, recognizing that mental health is influenced by biological, psychological, social, spiritual, and lifestyle factors. I provide compassionate, evidence-based, and nonjudgmental care in a safe environment where clients can openly discuss their concerns. Together, we work to develop a personalized treatment plan that supports healing, resilience, and long-term wellness.
