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 believe that healing happens when people feel truly seen, heard, and accepted. As a fun-loving person who is still a child at heart, I strive to create a welcoming, authentic, and nonjudgmental space where clients of all ages can feel comfortable being themselves. My goal is to meet you where you are, honor your unique experiences, and walk alongside you as you navigate life’s challenges.
I specialize in working with children, adolescents, and adults who are experiencing the effects of trauma, anxiety, and other challenges that impact daily functioning, relationships, and overall well-being. I am also passionate about providing affirming and supportive care to members of the LGBTQIA+ community, ensuring that every client feels respected, valued, and empowered throughout the therapeutic process. Additionally, I am proficient in American Sign Language (ASL) and am committed to fostering accessible and inclusive care for members of the Deaf and hard-of-hearing communities.
My approach combines compassion with evidence-based practices. I am trained in Cognitive Behavioral Therapy (CBT), trauma-focused counseling, and the SYMBIS Premarital Assessment. Whether you are seeking support for personal growth, healing from past experiences, strengthening relationships, or managing life's stressors, I am committed to helping you build resilience, discover your strengths, and create meaningful change.
I believe that every person deserves a space where they can feel safe, understood, and empowered to grow. My hope is to help you build on your strengths, overcome obstacles, and move toward a life that feels more connected, balanced, and fulfilling.
I have a Ph.D in Counseling. I've been a therapist since 1984 and I listen very well. I help clients with anxiety, depression and relationship issues and more.
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.
