Meet Our Neurosurgeons

All our physicians are board certified or board eligible. To ensure excellent patient care, they educate themselves through continuing education courses on new techniques and procedures. Some have specifically enhanced certain areas of their practice, such as minimally invasive surgery, spinal fusions, endovascular procedures, and robotic spine surgery.
