Our behavioral and rehabilitation psychologists and neuropsychologists—experts in brain functioning—are integral members of our interdisciplinary clinical teams, and are fundamental to the assessment and personalized plan development for each patient. They understand how the structure and function of the brain relates to specific psychological processes, like memory, critical thinking and judgment, and how those processes may affect behavior.

Psychologists guide the assessment of progress, making sure each team member keeps the whole person in mind – including his or her interests, profession or work history, and hobbies—and adjusts the treatment plan for individual needs so that the person can thrive in the real world.
