About Neurocognitive Specialty Group

Neurocognitive Specialty Group (NSG) is one of the largest private neuropsychology practices in the United States. Founded by Nicholas Wisdom, PhD, ABPP-CN, NSG has grown from a single Houston-area clinic to a multi-state practice with more than 30 providers, 7 clinic locations, and operations across Texas, Florida, Georgia, Mississippi, and Louisiana.

What We Do

NSG specializes in the assessment of brain-behavior relationships — how neurological conditions, injuries, and psychiatric disorders affect cognition, emotion, and daily functioning. Our services include:

• Clinical neuropsychological evaluations for dementia, TBI, stroke, epilepsy, and other neurological conditions
• Forensic neuropsychological evaluations for legal, civil, and criminal proceedings
• NFL and NCAA concussion settlement evaluations (BAP and MAF)
• Psychological assessments for mood disorders, ADHD, learning disabilities, and other conditions
• Counseling and therapy
• FAA neuropsychological evaluations for pilots

Our Team

NSG providers hold doctoral degrees in clinical psychology or neuropsychology and have completed accredited internships and postdoctoral fellowships. Multiple NSG neuropsychologists are board certified by the American Board of Professional Psychology (ABPP) in Clinical Neuropsychology — the highest credential in the field.
