ADHD therapists and psychiatrists in Ellicott City, MD

My intention is to provide a judgment-free space where we can talk about what is going on and collaborate to move forwards in the best way possible. I am flexible in my approach to counseling, and I tailor my counseling style based on the needs of each person I work with. I enjoy working with a wide range of clients (age, gender, concerns, etc.) and I am passionate about what I do. I am into fitness and healthy lifestyle, and I support my clients with creating their own foundation of wellness.

Hi! I'm so glad you're here. I’m Hunter Garrett, a board-certified Psychiatric-Mental Health Nurse Practitioner dedicated to partnering with children, teens, and adults as they navigate life’s hardest seasons. I have spent my career in a diverse variety of clinical settings and environments, working with patients from all backgrounds. I completed my advanced training at Vanderbilt University, where I focused on compassionate and holistic, evidence-based mental health care. Those experiences shaped my belief that every person deserves to feel seen, heard, and treated with genuine respect.

I am Dr. Christie Simon-Waterman, a dually certified Family Nurse Practitioner (FNP-BC) and Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) with over a decade of experience providing compassionate, evidence-based, and holistic care across the lifespan. My clinical background spans primary care, mental health, and community-based health, allowing me to care for the whole person—mind, body, and spirit.

I earned my nursing education at Coppin State University and completed my doctoral training with a strong focus on health equity, leadership, and integrated care delivery.

In my practice, I specialize in:

• Anxiety, depression, trauma-related conditions, and mood disorders
• Integrated mental health treatment
• Substance use–related concerns and recovery support
• Care for underserved and marginalized populations

My approach is empathetic, collaborative, and trauma-informed. I believe healing happens best when clients feel heard, respected, and empowered. Together, we develop personalized treatment plans that may include therapy, medication management when appropriate, lifestyle interventions, and ongoing support tailored to your goals.

Above all, I am committed to creating a safe, supportive responsive space where clients can build resilience, restore balance, and move forward with confidence and clarity.

As a licensed mental health therapist, I believe prioritising mental health is important for happiness and balance. Taking the first step and seeking help can be the biggest hurdle. I look forward to walking with you on your mental health journey!

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.

I specialize in Anxiety, ADHD, Depression, PTSD, Panic disorder and mood disorders. I also offer ADHD testing for children and adults online and in-person. I offer both medication management and therapy.
