Dr. Leonard F. Koziol is a clinical neuropsychologist with specialty board certifications in Neuropsychology and Pediatric Neuropsychology. He works with children, adolescents and adults with attention or concentration problems, memory difficulties, executive dysfunction, and learning disabilities

He also provides consultations and clinical supervision for other practitioners. He offers post-doctoral education and training for neuropsychologists, clinical psychologists, physicians in related disciplines, and occupational, speech/language, and physical therapists who wish to update their knowledge base.

Dr. Koziol has also served as a forensic psychologist expert in legal proceedings, and is available for case consultation and expert testimony.


Dr. Koziol has authored numerous book chapters and peer reviewed journal publications (see his CV for a complete list of publications). He edited several special edition journals on the topics of ADHD, Executive Functioning, and the role of the cerebellum in movement and cognition. He has achieved the highly unusual and respected "three-peat" accomplishment of publishing three specialty topic papers within the same specialty journal within a 12-month period of time.


His first paper covered the topic of the neuroanatomy of expertise and giftedness; his second paper proposed the first comprehensive neuroanatomy of sensory integration and sensory processing disorders; his third paper explains the neuroanatomic relationship between movement and thought. These papers address important issues and topics not only in pediatric neuropsychological development, but also with respect to understanding brain-behavior relationships across the lifespan (check Publications on the right to download these papers).


At this time, Dr. Koziol is primarily publishing by special invitation from editors. Current accepted topics include a journal series on the development of brain networks and brain systems in children, and how these systems affect attention, learning, and executive functioning; and book chapters about the role of the cerebellum in language disorders, and the neuroanatomy of ADHD.
