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.
I help people develop healthier strategies for meeting their needs, especially in relationships. If you have been impacted by stress, trauma, or loss, or if things just aren't working, please get in touch. With over 10 years of experience providing care, I am ready to help you!
Seeking therapy can feel vulnerable, and my goal is to create a space where you feel safe, understood, and not judged. I work with clients ages 9 and up, including individuals, couples, and families, who may be struggling with anxiety, depression, emotional overwhelm, or patterns in relationships that feel hard to change. I’m especially passionate about helping people build healthier relationships—with themselves first, and then with others. Whether you’re navigating challenges in intimate relationships, family dynamics, friendships, or simply trying to feel more grounded in who you are, I believe meaningful change is possible with the right support. I offer both virtual and in-person sessions and value meeting clients where they are—emotionally, relationally, and practically.
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.
Thank you for stopping by! I am excited to get to know you and begin this beautiful journey of growth. Whether you are starting a new journey or you’re looking to pick up where you left off, I’m glad you stopped by!
It is my passion to work with people, as they challenge themselves to grow and evolve. Many of us experience challenging feelings of depression, anxiety, relationship stress, and stress of dealing with the many transitions of life. At times, these challenging feelings can make us feel alone or isolated from our communities of love and support. I believe that I am here to walk alongside you and provide insight and support as you begin to see yourself grow and reach the goals that you set for yourself. I primarily work from a narrative perspective, but I pull from many different approaches to create a safe and efficient environment for my clients to explore and reflect on themselves and their situations.
Hello! I have experience working with adolescents and adults using a variety of therapy techniques in individual and group therapy sessions. I work with a variety of treatment modules including CBT, DBT, motivational interviewing, existential therapy, acceptance and commitment therapy, and mindfulness. I have worked extensively in crisis experience and with clients in crisis partial hospitalization (PHP), intensive out-patient (IOP), and in school settings.
