Mental health care should feel safe, supportive, and built on trust. As a Psychiatric Mental Health Nurse Practitioner with over 10 years of experience in the medical field, I am deeply committed to caring for the whole person and meeting individuals where they are in their mental health journey.
I work with children, adolescents, and adults, and support individuals navigating ADHD, anxiety, depression, mood disorders, and other mental health challenges. My experience across a variety of clinical settings allows me to blend medical expertise with a thoughtful, compassionate approach to care.

I also value working alongside therapists and other providers to support comprehensive care.
Above all, I value the person—not just the diagnosis. I strive to create a welcoming, non-judgmental space where patients feel heard, respected, and supported. Taking the first step toward mental health care can feel overwhelming, and my goal is to make that process feel clear, compassionate, and empowering.

With over 15 years in nursing, my foundation in healthcare was built long before becoming a board-certified Psychiatric Nurse Practitioner. Those years at the bedside shaped how I see people — not as diagnoses or medication lists, but as whole human beings with stories, stressors, strengths, and resilience.
I treat patients across the lifespan and approach care holistically, recognizing the connection between mind, body, environment, and lived experience. I believe mental health treatment works best when it is collaborative, culturally aware, and rooted in trust. My style blends thoughtful medication management with therapeutic support, because healing is rarely just about a prescription — it’s about feeling heard, understood, and supported.
I am empathetic and thoughtful in my approach, while also providing clear guidance and clinical insight. I strive to create a safe, nonjudgmental space where patients can show up as they are. Whether navigating anxiety, depression, trauma, mood disorders, or life transitions, my goal is to help individuals feel more grounded, empowered, and confident in managing their mental wellness.
Mental health care should feel human. My role is to walk alongside my patients, offering clinical expertise, compassion, and practical tools that support meaningful, lasting growth.
