Obsessive-compulsive disorder therapists & psychiatrists in Bellaire, TX

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.

Hi, I’m Mariam Opafunso, a board-certified Psychiatric Mental Health Nurse Practitioner. I earned my Master of Science in Nursing from Ohio University and have experience working in both inpatient and outpatient behavioral health settings. I specialize in treating anxiety, depression, ADHD, bipolar disorder, and other mood-related concerns, as well as eating-related conditions in adolescents and adults.

Outside of my professional role, I value balance and growth, and I show up fully for the people I serve. I understand that seeking help can feel overwhelming, and I create a space where you feel comfortable, respected, and truly heard.

Have you been feeling stuck in your thoughts, in your relationships, or in life as a whole? Do you experience unmanageable stress or anxiety? Or do you experience what seems like a loop of intrusive thoughts, then repetitive behaviors or habits that lead you to believe that you may have OCD? If you answered yes to any of these questions, you don’t have to go this path alone. Together, we can begin a transformative journey, where treatment becomes your pathway to greater relief.

Welcome. I’m glad you’re here.

Reaching out for support can feel overwhelming. I aim to create a safe, collaborative, and grounded space from the beginning. I meet clients where they are and move at a pace that feels manageable and respectful.

I work with children, adolescents, adults, couples, and families experiencing anxiety, trauma, addiction, and relationship challenges. I also specialize in complex and developmental trauma.

I support clients in integrating their spiritual and cultural values into therapy when desired and clinically appropriate. I was born in New Orleans and bring a culturally informed perspective shaped by my Latina, Indigenous, Christian, and Sephardic Jewish backgrounds.

I became a therapist because I have a deep commitment to helping people recognize and build their own strengths, especially during periods of feeling stuck, overwhelmed, or disconnected. I understand that seeking support takes courage, and I work to create a space where clients feel heard, understood, and supported throughout the process.

I earned a Master of Social Work (MSW) and PhD from Tulane University, as well as a Master of Public Health (MPH) from Tulane University’s School of Public Health and Tropical Medicine. I am a Licensed Clinical Social Worker (LCSW) in Louisiana and Texas, and a Licensed Independent Clinical Social Worker (LICSW) in Minnesota. I also hold a Licensed Addiction Counselor (LAC), Licensed Prevention Professional (LPP), and Certified Employee Assistance Professional (CEAP).
