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.

    I have a great deal of professional respect and regard for Dr. Viljoen. As a neurosurgeon, he has always communicated with me in a professional, direct, and above board manner which I appreciate and value. It is clear to me that he is a master technician where his surgical skillsets are concerned and I have every confidence that I am in the "right hands" regarding my pending surgery. I admire and respect him for taking the time to frame the surgical and recovery process. I give him an A+ as well.
