Thank you for stopping by! I am excited to get to know you and begin this beautiful journey of growth. Whether you are starting a new journey or you’re looking to pick up where you left off, I’m glad you stopped by!
It is my passion to work with people, as they challenge themselves to grow and evolve. Many of us experience challenging feelings of depression, anxiety, relationship stress, and stress of dealing with the many transitions of life. At times, these challenging feelings can make us feel alone or isolated from our communities of love and support. I believe that I am here to walk alongside you and provide insight and support as you begin to see yourself grow and reach the goals that you set for yourself. I primarily work from a narrative perspective, but I pull from many different approaches to create a safe and efficient environment for my clients to explore and reflect on themselves and their situations.
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 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.
As a counselor, I feel like mental health is a journey that is easier with a guide. I believe in empowering my clients and giving them the information and confidence to choose the paths along their journey that are best for them. I have been fully licensed since 2018 and I enjoy working with adults and couples.
Our current and past life circumstances can often leave us with feelings of stress, anxiety, and sadness. These emotions can be confusing and difficult to manage and process. My goal is to come alongside clients to reach personal goals, using warmth, understanding, and acceptance. I will work with you, with you in the driver’s seat, to set goals, explore and gain understanding of yourself, process your emotions in a safe space, reframe negative beliefs about yourself, and find solutions that work for you. I enjoy working with clients with a variety of concerns including general anxiety, depression, trauma, and relationship issues.
