My clinical mission is to advance the science and practice of cerebrovascular neurosurgery to new uncharted frontiers. I aim to provide patients seeking neurosurgical treatment at Duke Health with world-class clinical care and surgical management. I partner with patients and their families to achieve excellent clinical and surgical outcomes. I treat patients as I would treat my own family members: with passion, compassion, and respect. I do my best to give patients hope that they might find at other places. I lead a team of scientists and clinicians that strive to make innovative advances in treatment devices, alternative therapeutic agents for cerebrovascular diseases, and surgical approaches. If you or your loved one have a cerebrovascular disease, such as a brain aneurysm, AVM, dural AVF, stroke, intracranial atherosclerotic stenosis, carotid diseases, moyamoya, or vascular tumors, and want world-class care, Duke Health must be your choice.
