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 into a multi-state practice with more than 30 providers and 8 clinic locations across Texas, Louisiana, Mississippi, Georgia, and Florida.

What We Do

Neuropsychology is the assessment of brain-behavior relationships: how neurological conditions, injuries, and psychiatric disorders affect memory, attention, reasoning, emotion, and daily functioning. NSG applies standardized testing with validity measures to answer a specific clinical or legal question, and reports findings in terms the referring party can act on.

  • Clinical neuropsychological evaluations for dementia, traumatic brain injury, stroke, epilepsy, and other neurological conditions
  • Civil and criminal forensic evaluations, including independent medical examinations, competency and capacity evaluations, record review, and expert testimony
  • NFL and NCAA concussion settlement evaluations (BAP and MAF)
  • Psychological assessments for mood disorders, PTSD, ADHD, and related conditions
  • FAA neuropsychological evaluations and ATCS Tier 2 psychological evaluations
  • Telehealth screenings, counseling, and therapy

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 in Clinical Neuropsychology by the American Board of Professional Psychology (ABPP), the specialty’s recognized credential. Providers across our clinics serve as approved examiners for the NFL concussion settlement and conduct FAA evaluations.
