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 counselor, I feel like mental health is a journey that is easier with a guide. I believe in empowering my clients and giving them the information and confidence to choose the paths along their journey that are best for them. I have been fully licensed since 2018 and I enjoy working with adults and couples.
I work with adults 18 and older who feel anxious, depressed, distracted, emotionally overwhelmed, burned out, or unlike themselves. They may be struggling with ADHD, mood changes, stress, sleep disruption, low motivation, or difficulty functioning in daily life. Many are looking for mental health care that feels thoughtful, thorough, and individualized.
Our current and past life circumstances can often leave us with feelings of stress, anxiety, and sadness. These emotions can be confusing and difficult to manage and process. My goal is to come alongside clients to reach personal goals, using warmth, understanding, and acceptance. I will work with you, with you in the driver’s seat, to set goals, explore and gain understanding of yourself, process your emotions in a safe space, reframe negative beliefs about yourself, and find solutions that work for you. I enjoy working with clients with a variety of concerns including general anxiety, depression, trauma, and relationship issues.

Virtual & in-person • 13 mi away • Arlington, TX
As a licensed professional counselor and psychotherapist, my relationship with my client is the most important aspect of the process. I strive for connection and a collaborative spirit. It is always my goal to help the client with their unique and special needs. Whether someone struggles with anxiety, depression, grief, stress, trauma, or general relational issues, I want to develop a plan with them that will be customized to their needs, and specific to what their desired outcome is.
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.
