Hi, I’m Sabina Onwonga, DNP, a dual-certified Family Nurse Practitioner (FNP) and Psychiatric Mental Health Nurse Practitioner (PMHNP). I earned my Doctor of Nursing Practice (DNP) from UMass Global University and my Master of Science in Nursing (MSN) from the University of Texas at Arlington.
I provide compassionate, evidence-based psychiatric care and specialize in treating ADHD, anxiety, depression, bipolar disorder, PTSD, and counseling support, helping clients feel heard, supported, and empowered to reach lasting stability and wellness.
Patient care is my focus and I ensure my clients feel valued, seen and heard.
I provide compassionate, confidential psychiatric care designed to help you feel supported and understood. Each treatment plan is personalized, using evidence-based approaches tailored to your unique needs and goals. My goal is to create a safe, judgment-free space where we can work together to manage challenges such as anxiety, depression, mood changes, or sleep issues. Appointments are available virtually for your convenience.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) providing evidence-based, insurance-accepted mental health care to children, adolescents, and adults. I offer both psychotherapy and medication management, allowing for a comprehensive and integrated approach to mental health treatment.
My clinical work includes the assessment, diagnosis, and treatment of a wide range of mental health conditions, including anxiety disorders, depression, ADHD, mood disorders, trauma-related conditions, and other psychiatric concerns. I believe effective treatment is highly individualized, and I work collaboratively with clients to develop care plans that align with their goals, preferences, and lived experiences.
I strive to create a safe, respectful, and non-judgmental environment where clients of all ages feel heard and supported. Whether you are seeking therapy, medication management, or a combination of both, I am committed to providing compassionate care that supports long-term mental wellness.
