Clinical Neuropsychology Associates

About Us

Clinical Neuropsychology Associates (CNA) is a private, outpatient, group practice that is dedicated to providing clinical services, training and education, and clinical research in the field of neuropsychology. The founding partners, Dr. John Gordon and Dr. David Massari, opened the practice in 1984. As such, CNA is the longest established, private neuropsychology practice in the Philadelphia area.

CNA's clinical services include diagnostic assessment (neuropsychological testing) and consultation services regarding medical, psycho-educational, forensic and rehabilitation issues. In addition to providing neuropsychological evaluations, CNA offers treatment services, including cognitive rehabilitation and individual psychotherapy to patients who have a neurologic illness or trauma.

Our clinical staff hold faculty appointments at local universities and provide education and training, as well as clinical supervision to doctoral level and post-doctoral level students. We have also published in the field of neuropsychology and spoken at local and national conferences. Two of our senior neuropsychologists are diplomates with Board certification in clinical neuropsychology.
