Their approach is collaborative, strengths-based, and focused on diagnostic clarity. Rook integrates standardized testing, clinical interviews, developmental history, and real-world functioning to provide a clear picture of how cognitive, emotional, and behavioral factors interact in daily life, along with practical recommendations that support meaningful change at home, school, and work.

Rook has particular interest and experience in evaluating ADHD and executive functioning differences, autism spectrum features, learning disorders, and complex presentations where mood, anxiety, trauma-related experiences, and neurodivergent traits overlap. They also work with adults seeking evaluation later in life to better understand long-standing patterns that may not have been recognized earlier.
