ADHD therapists and psychiatrists in Greenbelt, MD

My name is Derrick C. Gibson — Licensed Professional Counselor, Elder at Brookside Ministry Church of God in Christ International, and someone who has spent his career showing up for people that many systems had already written off. I hold dual Master's degrees in Guidance and Counseling and Education from the University of Wisconsin-Stout, and my work has taken me deep into Kanawha County, West Virginia — into the schools, into the judicial system, and into the lives of families navigating some of the hardest circumstances imaginable. I've worked with domestic abuse survivors, sexual abuse survivors, at-risk youth, and individuals managing anger — not from a distance, but up close, with real investment in real outcomes. I also serve as a Christian Counselor, which means faith is not a footnote in my practice — it's woven into the foundation. If you're looking for a counselor who brings both clinical training and a grounded spiritual perspective, you've found one.

You should know that I take your concerns seriously, and I will meet you with compassion, respect, and zero judgment. I understand that reaching out for mental health support can feel intimidating, especially if you have faced stigma, felt dismissed in the past, or worried about what a diagnosis might mean. My goal is to help you feel safe and at ease from the very first conversation.

As a doctoral-prepared, board-certified Psychiatric Mental Health Nurse Practitioner with over eight years of experience in psychiatric and mental health care, I work with individuals across the lifespan. I commonly support people navigating depression, anxiety, PTSD, stress-related concerns, bipolar disorder, ADHD, and other emotional or behavioral health challenges. I approach each person as a whole, not a label, and I take the time to understand your symptoms in the context of your life, your stressors, your strengths, and your goals.

In our work together, you can expect a collaborative, patient-centered approach. I believe treatment works best when you feel heard and involved, so we will discuss what you are experiencing, what has helped or not helped in the past, and what you want to be different moving forward. If medication is part of your care, I prioritize thoughtful, evidence-based decisions, clear education about options, and ongoing adjustments based on your response and preferences. I also value practical strategies and supportive guidance that you can apply between sessions.

Most importantly, I am passionate about each person I serve because I know you are important, and I recognize the courage it takes to seek help. My role is to offer steady, professional support and a trusting relationship as you work toward clarity, stability, and lasting wellness.
