Our Team

All of our neuropsychology faculty are licensed, doctoral-level psychologists with specialized training and expertise in understanding how different medical conditions can affect children’s thinking and learning — their “cognitive” skills and performance — their development, and their behavior. We work together with licensed Psychological Associates who assist with testing under the supervision of the licensed psychologist, and with doctoral students in psychology, pre-doctoral interns, and postdoctoral fellows who also see many patients under the faculty’s supervision.
