EF skills act as an air traffic controller or orchestra conductor in the brain, directing thoughts toward behaviors that are crucial for academic and social success. The primary EF skills are identified as: Working Memory, Self-Monitoring,  Organization, Planning & Prioritizing, Impulse Control, Task Initiation/Completion, Mental Flexibility, and Time Management.













With offices in Tucker and Dunwoody, Susan provides one-on-one executive function coaching using evidence-based best practices. Through coaching, Susan teaches students how to organize, plan for tests/assignments, prioritize, manage timemaintain focus, access recall of important information, and study more effectively. Similarly, in working with adults, she helps to process daily demands and suggests ways to be more effective and productive at work and at home.
