Marissa Byrne DNP, PMHNP-BC
I am Marissa Byrne, a psychiatric nurse practitioner who delivers comprehensive mental health care to patients of all ages across North Dakota. I offer medication management along with supportive therapy, and I really enjoy getting to know each person I work with.
​
I take a collaborative, whole‑person approach to care. I want you to feel heard, understood, and involved in every step of your treatment. Watching clients grow, heal, and gain confidence is one of the most meaningful parts of my work. The values that guide me — hope, individuality, honesty, and hard work — shape how I show up for every session.
​
I earned my Doctor of Nursing Practice from Maryville University in 2023 and my Bachelor of Science in Nursing from the University of Mary in 2019. Those experiences helped build the foundation for the care I provide today.
​
When I’m not working, you’ll usually find me outside, spending time with my family, or happily organizing something.
Compassionate Care for All Ages
I believe mental health care should be grounded in safety, respect, and empowerment. In each session, I aim to foster a supportive environment where you feel heard, valued, and actively involved in your treatment decisions. I place great importance on building genuine, collaborative relationships with those I serve.
​
The core values that guide my practice—hope, individuality, honesty, and dedication—inform every aspect of my work. Supporting clients as they grow, heal, and develop confidence is one of the most rewarding aspects of my role.
