ADHD therapists and psychiatrists in Columbia, MD

I work with adults and teens who feel overwhelmed, anxious, or emotionally drained. They may be struggling with anxiety, depression, ADHD, mood changes, trauma, or life stress and feel stuck despite trying to cope alone. Others seek clarity around symptoms or support during major life transitions. Children and adolescents may struggle with emotional regulation, attention, mood changes, or behavioral concerns. Often, individuals or parents want relief and a clear path forward with a provider who listens and helps them feel more balanced, focused, and hopeful.

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.
