I am currently a Licensed Professional Counselor in the State of Texas. I work with a wide population of individuals including, children (10 years old and up), adolescents, and adults of all ages. I have been working with clients since 2009. During this time, I have worked in the community as a home-based provider, community mental health therapist, substance abuse therapist, college counselor, and private practice therapist. Much of my experience has surrounded helping individuals identify core issues and recover from past trauma. I believe in the healing power of being listened to and fully accepted.
Hi! I'm Obioma, a board-certified psychiatric mental health nurse practitioner (PMHNP) providing comprehensive mental health care to adults across Texas. I specialize in the diagnosis and treatment of anxiety, depression, PTSD, panic disorder, substance use disorder, and other mood disorders through personalized medication management and supportive care. My work is rooted in both clinical expertise and a genuine commitment to the people I serve.
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.
My approach to mental health care centers entirely around you. True healing happens when trust, safety, and collaboration come together. Whether you are navigating severe depression, managing long-term anxiety, or recovering from trauma, my goal is to provide a premium, supportive environment where you feel heard and empowered to reclaim a stable, fulfilling life.
As a board-certified adult psychiatrist, I bring unique depth to my clinical practice. I earned both my MD and PhD from the Albert Einstein College of Medicine, grounding my approach to medication management in advanced scientific research and evidence-based medicine.
My leadership and clinical training within the University of Texas Health System—including roles as Chief Resident, Assistant Medical Director, and Assistant Professor—deeply shaped my view of mental health. Having cared for individuals across institutions like MD Anderson, Memorial Hermann, the Dunn Behavioral Sciences Center, and Maui Memorial Medical Center, I possess the outpatient and inpatient expertise required to manage complex clinical cases with complete confidence.
I provide convenient, high-quality telepsychiatry and virtual care for adults (ages 18 and older) actively located in Texas, California, Hawaii, and Alaska.
Primary Clinical Focus Areas:
Above all, I believe in partnering with you as a collaborative ally. My practice is a safe, sophisticated space where clinical excellence is a given, and we work together to help you rediscover hope and transformation.
Often times people consider engaging in therapy when life may feel unbalanced. Sometimes this may be due to emotions that are not manageable or needing support to get through challenging situations. My goal is to help you live a more authentic life that can be enjoyable and meaningful to you. I have a clinical background in supporting individuals and families who have experienced trauma, relationship challenges, or may be experiencing a current crisis that is impeding their daily life.
