We also handle most general neurology complaints, including stroke, epilepsy, sleep disorders and neck and back injury. We welcome industrial and Workmen's Compensation patients and take most insurance plans. We specialize in the use of new approaches to pain that do not involve narcotics.

As we progress in this 21st century it is imperative that we modernize both the diagnosis of neurological disorders and their definitive management. 21st Century Neurology is involved in both education and innovative clinical and laboratory research aimed at improving the lives of people who must deal with these complex problems. Neurology has finally come into its own as a mature branch of medicine, and we are now able to offer effective treatment as well as sophisticated diagnostic methods.
