Hello, my name is Miguel A. Diaz and I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a Doctor of Nursing Practice (DNP) degree. I was born and raised in rural South Texas, which gives me a deep understanding of the unique challenges our local communities face when it comes to mental health care. My experience as a U.S. Army veteran has taught me the importance of resilience, service, and compassion—values I bring to every client relationship.
I specialize in providing psychiatric evaluation, medication management, and treatment for a wide range of mental health concerns, including anxiety, depression, and ADHD. My practice focuses on increasing access to care for children, adolescents, adults, and seniors, especially those living in underserved rural areas. Whether you’re new to mental health treatment or looking for ongoing support, you can expect care that is empathetic, evidence-based, and tailored to your individual needs.
I welcome you to reach out and take that first step toward improving your well-being.
After the Air Force I graduated from Nicholls State University in Louisiana as an RN, I then joined the Navy Nurse Corps. In my 20yr career I have worked in-patient psychiatry, post-surgical, oncology (three different settings), home infusions, and a private physicians office. While in NP school, I worked as an in-patient staff nurse at Harris County Psychiatric Center. My special interests are in adolescents, eating disorders, and PTSD (esp veterans).
My clinical style is warm, structured, and collaborative. I emphasize clear communication and shared decision-making with my patients. I strive to create a safe and non-judgmental environment where people feel heard and respected.
I have an AGACNP background, which supports my ability to assess medical comorbidity and understand complex medical/psychiatric overlap. I am also DOT-certified, which reflects my knowledge of safety-sensitive considerations and careful medication risk assessment.
I am a Psychiatric Mental Health Nurse Practitioner who works with adults experiencing anxiety, depression, trauma-related symptoms, mood disorders, OCD, and substance use concerns. My background includes structured treatment settings supporting recovery, stabilization, and long-term mental health management.
I provide warm, practical, and judgment-free care where clients feel heard and supported. Many people come to treatment feeling overwhelmed or unsure where to begin, and my goal is to simplify the process and provide clear direction forward.
I focus on thoughtful medication management and practical strategies that support lasting stability and meaningful progress.
I’m Dr. Emem Nkanga, Doctor of Nursing Practice. I believe that everyone deserves a personalized and compassionate approach to mental health care. I bring over 20 years of experience in healthcare, with a focused dedication to psychiatry over the past 4 years. My passion lies in supporting mental health and emotional well-being.
I work with children ages 10 and above, adolescents, and adults from diverse backgrounds who are experiencing challenges such as anxiety, depression, ADHD, PTSD, bipolar disorder, OCD, insomnia, and more.
