Additional Information

Dr. Jonathan Gross is a fellowship-trained neuropsychologist and licensed psychologist with extensive experience in the fields of neuropsychology, neuropsychological rehabilitation, and psychological assessment. He has trained at various centers of excellence including Emory University, the Mount Sinai Medical Center, and Brooks Rehabilitation Hospital. Dr. Gross holds expertise in the evaluation of traumatic brain injury and other neuromedical conditions including dementia, stroke, and developmental disorders (such as Autism Spectrum Disorder and intellectual impairment). He devoted ten years of practice serving US Veterans through the VA community provider system where he evaluated and treated veterans for traumatic brain injury, dementia, posttraumatic stress disorder, and associated conditions. Dr. Gross employs a comprehensive and in-depth approach to assessment which allows him to identify a diverse range of factors that contribute to symptoms including effects of brain trauma, symptom exaggeration, premorbid factors, psychosocial history, emotional distress, and effects of chronic pain. He has been retained as an expert in criminal cases to evaluate competency to proceed (i.e. stand trial), mental state at the time of offense (i.e. the insanity defense), and risk of violence. Dr. Gross's rigorous style is aimed at providing objective, data-driven answers to questions most relevant to litigation.
