About Me

I’m a urologist, with a major focus on the management of kidney stones. At The Ohio State University Wexner Medical Center, we perform more than 500 surgeries a year related to kidney stones.

Research at the Comprehensive Kidney Stone Program ties directly to our clinical program. I explore new treatments for kidney stones including medications and surgical techniques. I also study the use of lasers in the treatment of stones.

My goal is to personalize the health care delivered to each patient. I work with my patients to develop individualized treatment plans. Effective treatment of stones can provide relief of an acutely painful episode and also reduce future stone recurrences. Such treatment can significantly improve a patient’s quality of life.

My wife, Dr. Eunice Oppenheim-Knudsen, is a family practice physician who works at Ohio State’s Wexner Medical Center’s Upper Arlington Clinic. We both enjoy living in the Columbus area and working at a top tier medical center. We strive to maximize the quality of life for our patients.
