Dr. John C. Barr

Neurosurgery is a challenging field of medicine but is very rewarding. I specialize in brain tumor, pituitary neoplasm, and complex spinal disorders and deformity. I find it important to educate my patients on the surgical options available to them. I believe building a great patient-provider relationship is essential to achieving excellent clinical and surgical outcomes.
