About Dr. Oni-Orisan

He treats ischemic and hemorrhagic stroke, brain aneurysms, arteriovenous malformations, carotid disease, acoustic neuromas, and skull base tumors, along with degenerative and traumatic spine disorders, brain tumors, trigeminal neuralgia, Chiari malformation, carpal tunnel syndrome, pituitary adenomas, and traumatic brain injury.

At Performance Sports and Spine, Dr. Oni-Orisan sees patients whose spine or nerve condition may need a surgical opinion. Many arrive after conservative care with Dr. Desai or an evaluation by one of the practice's neurologists, so imaging, test results, and treatment history are already in one place. Surgery is recommended only after conservative options have been considered, and always with a clear explanation of why, what's involved, and what recovery looks like.

Born and raised in Ann Arbor, Michigan, to Nigerian immigrant parents, he lives in the area with his wife and three young daughters, and enjoys sports, music, and travel.
