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.
Are you ready to discover inner peace, dreams, invest in yourself, and/or simply foster healthy relationships? If the answer is yes, then I am ready to meet you where you are to begin the process. As a counselor, my goal is to incorporate a judgment-free, safe, and restorative environment for couples, individuals, and families to work through life challenges.
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.
My clients may find that they are struggling with trusting themselves or others in relationships, have difficulty feeling safe or confident in their own body, and/or some have past difficult/confusing/traumatic events that can make them feel stuck. I specialize in helping teens, adults, and families with Anxiety, Panic Disorder, OCD, Trauma, Eating Disorders, Depression, Adjustments, Life Stressors, and Grief and Loss.
