About Me

I’m a neurosurgeon specializing in the treatment of adult spinal deformity and complex reconstructive spine surgery. I also serve as an assistant professor of neurosurgery at The Ohio State University College of Medicine. I received my medical degree from the University of Nebraska. In addition, I completed an internship and a neurosurgical residency at the University of Iowa and a fellowship in adult spinal deformity from Northwestern University.

My research focuses on spinal biomechanics, clinical outcomes research and device development, and I have three U.S. patents. I’m also a member of The Ohio State Neurological Society and the Congress of Neurological Surgeons.

What I enjoy most about The Ohio State University is the academic setting. I can be involved in resident education and research while providing my patients with quality care. The resources and medical experts on staff at The Ohio State University allow me to conduct meaningful research and provide better treatment options to my patients.

    Dr. Viljuen was thorough in his explanation of my problem. He took a lot of time to explain what needed to be done and answered all my questions. He even called me to answer a couple of questions I had after my appointment.

    I do not like the fact that Dr. Viljoen rolled his eyes at me the whole time I'm trying to talk to him about my back, and when I asked to fix it he brushed me off. Totally not acceptable. Dr. is supposed to listen & be helpful & friendly.
