Hello, I’m Marie Oneus, a Psychiatric Mental Health Nurse Practitioner committed to helping individuals find balance, clarity, and emotional well-being. With over a decade of experience in nursing and behavioral health, I specialize in treating anxiety, depression, trauma, mood disorders, and other complex mental health conditions. My approach is compassionate, collaborative, and evidence-based, combining thoughtful medication management with supportive care. I strive to create a safe, non-judgmental space where clients feel heard, respected, and empowered in their mental health journey.
I take a holistic and trauma-informed approach to mental health care, recognizing that each person’s experiences, environment, and life circumstances play a role in their well-being. I focus on building trust and creating a supportive space where clients feel comfortable discussing their challenges openly.
In the first session, my priority is creating a comfortable, non-judgmental space where clients can openly share what they’ve been experiencing. We will talk about current challenges, mental health history, and what you hope to gain from treatment. I take time to answer questions, discuss potential treatment options, and begin building a plan.
