Dr. Jim C. Brasfield
Board-Certified Neurosurgeon Specializing in Spine

Dr. Jim Brasfield, main office located in Bristol, is a board-certified neurosurgeon who specializes in spine. In 1985, Dr. Brasfield completed his residency and founded his current medical practice, Bristol Neurosurgical Associates. He has practiced medicine in the TriCities region for more than 20 years, developing a strong reputation with his patients, employers, workers compensation carriers and health insurance plans who all share a desire for high quality medical care.

In 2008, recognizing that the national trend in spine care is to improve care of back and neck pain with a team of spine specialists from complementary disciplines working together, Dr. Brasfield founded TriCities Spine in Bristol, Tennessee. The spine center is a work in progress, with the goal of putting spine surgeons, non-surgical spine specialists and spine therapists under one roof for the convenience of the patient.

In the field of workers compensation, Dr. Brasfield has established a reputation in Tennessee and Virginia as a specialist in the treatment of work-related back and neck injury. Many of his patients are physically active and are involved in physical labor. Dr. Brasfield is keenly aware of his patients’ need for restoration of their previous performance level, and strives to get patients back to work and their recreational activities.

In a quest to improve clinical care and the efficiency of his medical practice, Dr. Brasfield co-founded a medical software company called E-Cure ( that creates a streamlined, paperless office.

Dr. Brasfield lives in Bristol, Tennessee and has three sons. His hobbies include fishing and flying in the beautiful Appalachian region.
