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.

    Rude, no regard to patients feelings, all the answers was no! Without any acknowledgement, no time spent with me, rushed in and out of the room like I was bothering him and taking up his time

    Made to fell like I should not have been there! I was referred there by my physician did not come on my own! Nothing was explained - Just told he could not help me. We waited over an hour once put in the exam room - Dr. spent less than 10 min.

    The doctor was 1+ hours late for the appointment time. He didn't seem to really listen to me regarding my issue with pain. It felt like he'd already made up his mind about me before he even saw me.

    The doctor was the worst we have ever experienced. He came into the room and did not even introduce himself or say hello. His first question to us was "what is your problem today?" He didn't look up the medical records, because he said the system had changed and couldn't find it. He said that the people reading the images often don't know how to read images correctly. He offered no solutions, advice or anything of importance. It was the most negative situation for such a popular place to receive healthcare.

    He was cold and seemed disinterested in my well-being.
