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.
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.
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.
My therapeutic style remains flexible and collaborative, focusing on your individual strengths, needs, and motivation. I consider it a privilege to partner with my clients in this work and to be trusted by them as they share their stories. I strive to create a collaborative space for you to share and examine your own behaviors, feelings, and thoughts; for as Cheryl Richardson has noted, “People start to heal the moment the feel heard.”
