Prior to arriving at Duke, I was faculty at UT Southwestern where I had a dual appointment at the North Texas VA for 10 years. During this time, I was one of the highest volume robotic VA surgeons treating veterans with urologic cancer in addition to my clinic practice at UTSW. I joined the Urology department at Duke in 2024. At Duke, I have continued my focus on urologic oncology, specifically prostate, bladder and kidney cancer. I have a particular interest in prostate cancer. I was one of the earliest adopters of a novel surgical technique termed the Retzius Sparing Prostatectomy, which allows for the earlier return urinary control. I have further adopted a novel technique for the treatment of localized prostate cancer known as irreversible electroporation (IRE). This technique is a form of focal therapy for carefully selected patients. The advantages of IRE include less urinary and sexual side effects than conventional prostate cancer treatments. In addition, my clinical expertise includes advanced robotic reconstruction of the upper urinary tract. These procedures involve using segments of bowel or buccal grafts (inner lining of the cheek) to reconstruct damaged ureters.

I’m a reconstructive urologic surgeon who also cares for cancer survivors. Cancer survivorship care focuses on providing patients and families relief from the symptoms, pain and distress that may develop after and during cancer therapy. I find it gratifying to help a patient that has a significant problem and increase their quality of life. I decided I wanted to go into medicine while in high school after feeling a sense of duty to serve those around me; this was the same calling that drew me to service in the military for 23 years. I came to Duke after my active duty service in the Army was completed in 2010 and since then, my family has really become a “Duke family.” We regularly attend Duke Football games and other sporting and social events. My wife also works here, my kids have expressed interest in attending college here and we all regularly wear the Duke blue colors on weekends.
