As a special needs dad, a former Spanish teacher, former school counselor (MEdSC), and nurse (MSN), I bring a broad range of experiences to my clients. As a nurse, I have worked PACU, ER, and geriatrics. My goal is to work with the client to reach their goals through the use of counseling, supplements, and medication as needed. I enjoy using belief systems as part of my counseling if desired.
Like many providers, I have worked with many clients with depression, mania, and anxiety. As a previous teacher/school counselor, I understand the impact of ADHD on the student, the classroom, the teacher, and the family.
I think it is important for prospective clients to know that I want to help both now and in the future. For this reason, there are drugs that I don't prescribe (stimulants and benzos) because of the long-lasting side effects.
My hobbies include playing the piano, singing, gardening and family.
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.
