Bipolar disorder therapists & psychiatrists in Mcallen, TX

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 am a board-certified psychiatrist with 9 years of experience in adult, child, and adolescent psychiatry. My practice is grounded in patient-centered, evidence-based care for a wide range of mental health conditions, including depression, bipolar disorder, anxiety, ADHD, PTSD, sleep disorders, and substance use disorders. I offer comprehensive psychiatric evaluations, individualized treatment planning, medication management, and ongoing follow-up care.

Every person has a story. The culmination of experiences in one's life shapes how they view themselves, their relationships, and the world. I have a passion for helping clients celebrate their unique strengths and gifts they share with others. With experiences in both private practice and hospitals, I have noticed a particular need for clients to separate their view of themselves from their current difficulties and circumstances. In spite of where clients may find themselves at the moment, my belief is that they have overcome every difficulty, challenge, and trauma that they have faced up to the present moment. As such, they will withstand their current circumstances, and will again declare victory.

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.

My practice focuses on increasing access to care for children, adolescents, adults, and seniors, especially those living in underserved rural areas.
