Book a therapist or psychiatrist in Rockwall, TX covered by United Healthcare

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.

Dr. Adolf Malik, DNP, APRN, completed his master’s degree at the University of North Carolina in Greensboro, followed by a post-master’s and a doctoral degree in nursing practice at Winston-Salem State University, NC. He also completed a post-doctoral degree in psychiatric mental health practice at Frontier Nursing University. He is board-certified in Adult, Child, and Adolescent Psychiatry; a Family Nurse Practitioner, a DOT Medical Examiner, and a SAMHSA (X-Waiver) addiction provider.

You may feel stuck in patterns that no longer serve you - carrying anxiety, stress, or the weight of past experiences while trying to manage relationships, family dynamics, or major life transitions. It can be exhausting to keep pushing forward without clarity or relief, especially when things feel overwhelming or difficult to untangle on your own. You don’t have to navigate this alone. I offer a supportive space where you can slow down, feel understood, and begin making sense of what you’re going through.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) providing compassionate, holistic mental health care for individuals across the lifespan. I work with clients experiencing anxiety, depression, ADHD, bipolar disorder, PTSD, insomnia, schizophrenia, and substance use challenges, helping them regain balance and confidence in their lives.

My approach to care is warm, empowering, and collaborative. I believe every person deserves to feel heard, understood, and supported while navigating their mental health journey. I work closely with each client to develop a personalized treatment plan that supports emotional well-being, symptom management, and long-term stability.

With experience in both inpatient and outpatient psychiatric settings, I have supported individuals facing complex mental health challenges and life stressors. I provide comprehensive psychiatric evaluations, medication management, and supportive therapy, while incorporating lifestyle and coping strategies that promote lasting wellness.

I am passionate about helping people develop the tools and understanding they need to take control of their mental health. My goal is to create a safe, judgment-free environment where clients feel comfortable sharing their experiences and working toward meaningful change.

I work with partners, couples, and marriages to improve communication, trust, commitment and general satisfaction within relationships. I work with couples who are in current and loving relationships, and do not specialize in separation or divorce. I refer couples out who are not in love with each other anymore.

I also hold therapy for individuals, around such topics as anxiety, depression, grief/loss, family relationship issues, work stress, and other things to see changes in life.

1st intake session: typically 55 minutes

I'm a Psychiatric Mental Health Nurse Practitioner specializing in comprehensive, evidence-based care for individuals experiencing depression, anxiety, ADHD, bipolar disorder, and other mental health conditions. With years of healthcare experience and a compassionate, patient-centered approach, I provide personalized treatment plans tailored to your unique goals and needs.

Whether you're seeking medication management, psychotherapy, or a combination of both, I work collaboratively with you to develop an individualized plan that promotes lasting wellness and improved quality of life.

I also offer Spravato® (esketamine) treatment for eligible adults with treatment-resistant depression and depressive symptoms associated with major depressive disorder. To better meet the needs of busy professionals, students, and families, evening and weekend Spravato appointments are available in a comfortable, supportive clinical setting.

My goal is to provide accessible, high-quality mental health care that empowers you to achieve emotional wellness and long-term recovery.

If therapy were easy, everyone would already be doing it. I work best with people who want a direct therapist, not just a sounding board. I believe that healing comes from doing the work. Real, lasting change demands full commitment—a willingness to show up daily to become the best version of ourselves.

With 24 years of experience as an LPC, my professional background spans leadership, clinical practice, and mentorship. Throughout my career, I have learned that people value connection - whether it’s through shared goals, emotions, or by being seen and heard. I work alongside adults and teens (16+) facing addiction, anxiety, depression, bipolar disorder, relationship difficulties, and parenting or teen struggles. Supporting military service members and veterans is also an important part of my work.

I work with individuals and couples who are tired of feeling stuck. Maybe it's anxiety, a marriage that isn't working, or the exhaustion of being neurodivergent in a neurotypical world.
