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.
After the Air Force I graduated from Nicholls State University in Louisiana as an RN, I then joined the Navy Nurse Corps. In my 20yr career I have worked in-patient psychiatry, post-surgical, oncology (three different settings), home infusions, and a private physicians office. While in NP school, I worked as an in-patient staff nurse at Harris County Psychiatric Center. My special interests are in adolescents, eating disorders, and PTSD (esp veterans).
My clinical style is warm, structured, and collaborative. I emphasize clear communication and shared decision-making with my patients. I strive to create a safe and non-judgmental environment where people feel heard and respected.
I have an AGACNP background, which supports my ability to assess medical comorbidity and understand complex medical/psychiatric overlap. I am also DOT-certified, which reflects my knowledge of safety-sensitive considerations and careful medication risk assessment.
