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.
I strive for creating the conditions were humans can regain their curiosity, hope, and a new interactional perspective of themselves. Having also also known love, generosity, tolerance, respect and solidarity. I reject the need for cynicism: under the right conditions one can comfortably adhere to the unconditional confidence in the human potential for self-understanding, tolerance and positive change.

I’ve worked in a variety of mental health fields, including inpatient & outpatient psychiatric programs, residential treatment facilities, & a handful of private practices. These experiences have given me a multi-faceted view of the spectrum of care for mental health. I believe it has allowed me to truly understand every side of mental health treatment.
