Addiction therapists & psychiatrists in Duncanville, TX

Hi, I'm James Greenwald, a licensed professional counselor with 10+ years of experience in both private practice and public mental health services here in North Texas. I'm a graduate of Dallas Theological Seminary, and my training centers on concepts and skills from dialectical behavioral and family systems models of therapy. I specialize in assisting clients struggling with depression, anxiety, patterns of addiction, life transitions, boundaries, and various levels of trauma recovery.

Finding the right mental health provider can feel overwhelming, especially if you've tried therapy or medications in the past without getting the relief you were hoping for. My goal is to help you move beyond simply managing symptoms and toward feeling like yourself again.

I am a dual-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) and Family Nurse Practitioner (FNP-C) with over 16 years of healthcare experience. I specialize in treating adults with depression, anxiety, trauma, ADHD, insomnia, OCD, and treatment-resistant mood disorders. My advanced psychiatric training was completed through Monmouth University and Wilkes University, where I focused on Evidence-based psychiatric care.

I believe that effective treatment starts with understanding the whole person not just the diagnosis. Together, we'll explore the biological, psychological, and lifestyle factors contributing to your symptoms and develop a personalized treatment plan that fits your goals. My approach combines thoughtful medication management with practical therapeutic strategies that you can apply in everyday life.

For individuals whose depression has not improved after trying multiple antidepressants, I also evaluate and provide treatment options such as Spravato (esketamine) when clinically appropriate. My focus is always on finding the safest, most effective treatment based on your unique needs.

Patients often describe me as warm, approachable, honest, and solution focused. I strive to create a supportive, judgment-free environment where you feel heard, respected, and actively involved in your treatment decisions. Whether you're seeking help for the first time or looking for a new approach after previous treatments haven't worked, I'm committed to helping you build lasting emotional wellness and improve your quality of life.

Everyone wants to have more effective, more efficient brain power. We want to perform at our personal peak, without the use of psychotropic medications.

You’re not after a quick fix—you just want someone real to help you sort things out and walk with you through the hard parts.

Hello, I’m David. I work with individuals dealing with stress, anxiety, and major life changes, as well as those adjusting to injuries or ongoing health issues.
