About Us

Nassau Neuropsychology is a lifespan focused neuropsychology practice proudly serving individuals and families throughout Nassau County. We accept referrals from all across Long Island, the greater New York City area, and New York state. We provide comprehensive neuropsychological assessments, diagnoses and treatment interventions for children (ages 5+), adolescents, adults, and older adults (65+). Our goal is to better assist you in understanding you or your loved one’s individual cognitive strengths, while supporting areas for growth. As a lifespan neuropsychologist, Dr. Errera has been trained to evaluate, test, diagnose and treat a variety of neurodevelopmental, neurodegenerative, neurological, and neuropsychiatric conditions. Whether your cognitive challenges are longstanding or newly acquired, our testing experience helps you understand these difficulties and provides individualized recommendations to improve overall functioning, brain health, and cognitive resilience. We will help you implement these recommendations and explore accommodations in school, work, and at home.
