Hi, I’m Christopher, a board‐certified Psychiatric Mental Health Nurse Practitioner with a Doctor of Nursing Practice degree and a background in both healthcare and military leadership. My experience includes working in high‐intensity medical environments where I supported individuals facing significant stress, trauma, and life transitions. I specialize in helping people manage anxiety, depression, trauma‐related concerns, and high levels of stress. My goal is to provide care that is empowering, holistic, and supportive, helping clients build resilience and regain a sense of balance in their lives.
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.
If you’re the one everyone depends on but you feel anxious, burned out, or emotionally drained, you don’t have to keep pushing through alone. I work with adults who are high-functioning on the outside but overwhelmed on the inside, especially women, professionals, parents, caregivers, and veterans navigating anxiety, depression, trauma, ADHD, burnout, and major life transitions.
I’m a board-certified Psychiatric Mental Health Nurse Practitioner with a Master of Science in Nursing (MSN) and over 20 years of experience across diverse healthcare settings. As a veteran, I bring personal understanding of military culture and chronic stress. My approach is collaborative, culturally responsive, and judgment-free, blending evidence-based medication management with supportive, real-world conversation.
If you’re looking for care that feels thoughtful, respectful, and tailored to your life, not rushed or one-size-fits-all, invite you to schedule a consultation and take the first step toward feeling more grounded and supported.
I am a Psychiatric Mental Health Nurse Practitioner who is passionate about helping individuals improve their mental health and overall well-being. My goal is to create a safe and supportive space where clients feel heard, respected, and comfortable discussing what they are going through.
My background in nursing and advanced psychiatric training allows me to assess, diagnose, and treat a variety of mental health conditions. I work with adults experiencing challenges such as anxiety, depression, trauma, mood disorders, and stress-related concerns. I take a collaborative approach, working with each client to develop a treatment plan that fits their individual needs and goals.
I believe that mental health care should be compassionate, practical, and empowering. My goal is not only to help manage symptoms but also to support clients in building healthier coping strategies, improving emotional resilience, and creating meaningful changes in their lives.
