About Brooke

Care that starts with the whole picture.

Brooke helps young people build the skills and confidence to approach new experiences, manage challenges, and keep moving forward when difficult thoughts or feelings get in the way.

Across school-based and outpatient settings, she has supported children and adolescents with anxiety, selective mutism, OCD, ADHD, emotional dysregulation, learning differences, and giftedness. Her work considers the whole picture: each young person’s strengths, relationships, family, school, and broader environment.

That perspective shapes care that is grounded in evidence and responsive to the individual. Brooke values close collaboration with children, families, and school teams so that treatment reflects their goals and the realities of daily life.
