I’m a Psychiatric Mental Health Nurse Practitioner providing telehealth care across Texas. I’m passionate about helping clients feel heard, understood, and supported throughout their mental health journey. I believe every patient deserves a safe, judgment-free space to explore their challenges, build coping skills, and work toward emotional balance.
I prioritize collaboration and open communication, so you’ll always be an active participant in your care. My goal is to help you feel confident, empowered, and supported as you navigate your mental health journey.
I am Mary Nganga, a PMHNP-BC in state of Texas. I have more than 12 years of experience in mental health. I graduated with Bachelor in Nursing from University of Texas Arlington, and Masters in Nursing from Texas States University, San Marcos. My free time, I enjoy spending time my family, pet (Ruffy), and gardening.
As a board-certified, doctorally prepared psychiatric nurse practitioner, I treat a variety of mental health disorders using medication management as well as can incorporate psychotherapy within the session based on situational necessity. My focus is across the lifespan, including children and adolescents.
I love mental health, I love helping humans whether you need a listening ear, therapy, or medication. My clients vary from working parents, struggling students, divorced parents navigating co parenting, or someone recovering from loss and grief. I take pride in providing quality sound care in a non judgmental safe space.
Healing isn't linear and I understand that deeply, both professionally and personally. As a dual -certified Family and Psychiatric Nurse Practitioner, and an attorney, I bring a unique, comprehensive perspective to care. But more than titles, I bring lived experience.
I know grief intimately. The pain I carried afterwards was unexplainable. It didn't fit into a neat diagnosis or timeline. That experience shaped not only how I show up for others but why I do my work.
Whether you are navigating the aftermath of a death, a medical diagnosis, a relationship rupture, or job loss, I offer a safe, grounded and trauma focused space. I help clients process complex emotions, rebuild self-trust, and gently move toward healing, at your own pace.
If you're carrying something heavy, you don't have to carry it alone. I'd be honored to walk with you.
I have been a psychiatrist in private practice for 23 years. I believe everyone deserves to be understood. I seek to understand each patient as an individual human being to be able to accurately diagnose mental illness, and deliver the most effective care.
