Our Staff

Since its founding in 1954, the GNI has kept pace with the rapid advance in neurosurgery and technology in order to provide the latest and best clinical therapies. The Institute's surgeons are among the Southeast's leaders in the diagnosis and treatment of disabilities of the spine and brain among adults and children. All are certified by the American Board of Neurological Surgery. The staff of dedicated surgeons take time to share their knowledge and experience with medical students in the community and to conduct research projects with far-reaching implications for patient care.
