I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and DNP with graduate degrees from Molloy University. I have experience working with adolescents and adults facing various complex mental health issues, including depression, anxiety, stress, panic disorders, grief, and relationships concerns, in multiple settings.
I’m a Psychiatric Mental Health Nurse Practitioner with over 17 years of experience supporting adolescents, adults, and older adults on their mental health journeys.
My approach is warm, collaborative, and empowering. I believe that understanding yourself is the foundation of healing, and I focus on giving my clients practical tools, education, and guidance they can use every day—not just during sessions.
In our first session, I take the time to truly listen and understand your story, your goals, and the challenges you’re facing. Together, we’ll create a personalized and realistic treatment plan designed to support your growth, emotional well-being, and long-term success.
I am committed to providing compassionate, evidence-based care that helps you feel seen, supported, and equipped to move forward. My goal is to help you build confidence, develop lasting skills, and become the strongest version of yourself—one step at a time.
