Neurosurgeons often see patients after receiving troubling and confusing news or after a life changing event like a stroke, brain hemorrhage or traumatic injury. It is an absolute honor and privilege to help patients and their families during this time of need. I want patients to understand their condition, the available treatment options and what are the potential outcomes of therapy. My priorities are to carefully explain and counsel patients and families about the condition and to offer the safest approach to address the problem. I also enjoy hearing the patient's perspective and learning about what matters most to them. As a vascular neurosurgeon, I offer a comprehensive approach for the evaluation and management of cerebrovascular and spinal vascular disease, which may include medical therapy, open microsurgery, endovascular techniques, and radiosurgery. Neurosurgery is a constantly evolving field, and my goal is to combine the newest treatment advances with compassionate patient care.

About

John D. Nerva, MD is a fellowship trained, board-certified neurosurgeon who joined the faculty of the Medical College of Wisconsin in 2021. He specializes in the treatment of cerebrovascular and spinal vascular disease and is part of a select group of neurosurgeons with fellowship training in both open vascular microsurgery and endovascular techniques for the treatment of brain aneurysms, vascular malformations, and stroke. He also collaborates with radiation oncology to perform stereotactic radiosurgery for select vascular malformations at Froedtert-MCW.

Dr. Nerva grew up in Minnesota and graduated summa cum laude from the University of Minnesota. He also attended the University of Minnesota for medical school graduating with Alpha Omega Alpha honors. He completed neurosurgery residency at the University of Washington, during which time he also completed cerebrovascular fellowship training at Macquarie University in Australia. After residency, he received advanced training in minimally invasive endovascular techniques at the University of Florida. Prior to joining MCW, he was on the faculty at Tulane University in New Orleans.

Dr. Nerva's clinical research relates to patient outcomes and refinements of surgical and endovascular techniques for cerebrovascular disease. He has authored over 100 manuscripts, abstracts, book chapters, and presentations, including several at national and international meetings, and has served as key personnel on NIH/NINDS funded research studying computer simulations of brain aneurysm treatment. He is also recognized as a reviewer for several marquee peer-reviewed neurosurgical journals and has been invited to teach at regional and national neurosurgical courses.

Dr. Nerva performed my emergency brain surgery almost a year ago and I've been following up with him ever since. The one thing I appreciate most as a patient is that I've ALWAYS spoken directly with Dr. Nerva about my care. The amount of time he spends explaining my situation and detailing possible options, makes me feel like I'm his only patient (which I know is far from the truth) and this has allowed me to place all of my trust with his expertise. After all, he knows my brain way better than I do!
I am always treated with respect and diligence. Dr Nerva is the best surgeon
Dr Nerva was excellent, very concerned and willing to listen. Explained my condition and my options completely.
We met with Doctor Nerva in person and it went very well and Dr. Nerva did an extremely good job explaining what our next steps are
