As a Psychiatric Mental Health Nurse Practitioner (PMHNP), I’m trained at the graduate level in mental health care across the lifespan. I assess mental health concerns, diagnose conditions, prescribe and manage psychiatric medications, and provide psychotherapy. I also coordinate care with therapists, primary care providers, and other specialists as needed.
I am a board-certified Psychiatric mental Health Nurse Practitioner (PMHNP) with over 9 years of experience in mental health care as a Psychiatric Registered Nurse. I graduated with honors and am passionate about providing compassionate, evidence-based care to individuals across the lifespan. My clinical experience includes working with patients experiencing depression, anxiety, mood disorders, and severe mental illness in both inpatient and outpatient settings.
I am dual board-certified as a psychiatric-mental health nurse practitioner and family nurse practitioner with a passion for functional medicine. I believe mental health is best addressed by looking at the whole person—mind, body, and soul. I’ve been working in healthcare for over 20 years. Through my experience in mental health, I have the privilege of working with adults aged 21–60. I support individuals navigating anxiety, depression, ADHD, PTSD, OCD, mood disorders, and eating disorders, offering a safe and respectful space for growth and healing.
