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 mainly treat patients with genitourinary cancers including prostate, kidney, bladder, testicular and penile cancer.  My goal is to be attentive and devoted to my patients who are often dealing with complicated health problems. I try to personalize my care because every patient is different. I believe the future is promising because new treatments are being discovered every day. I am involved in clinical trials done through Duke University.  Clinical trials are designed to provide patients with access to the newest possible treatments. I am also part of our multi-disciplinary cancer team including urologic oncologists, geneticists, radiation oncologists, pathologists, radiologists, and other specialists.  I grew up in Cary and did all of my medical training in the Research Triangle Park area. I feel honored to practice in the same community I have lived in for more than twenty-five years.

I first recognized my passion for taking care of cancer patients during my internal medicine residency in the 1990s. At that time, new treatments were emerging and our understanding of this terrible and complicated disease was beginning to accelerate. I remember waking up each morning with new energy to get into the hospital to take care of my patients. Oncology embodied all of the reasons why I went into medicine; the compassion, the emotional connections, the incorporation of not just medicine, but psychological, emotional, and spiritual care. I enjoy getting to know my patients. I share in their joys and their challenges, and many almost become an extension of my family. In my time away from my patients, I enjoy spending time with my wife, four children and two dogs as well as oil painting, running, and cooking.

As a medical oncologist, I specialize in treating patients with head and neck cancers and lung cancers. I am passionate about patient education. I want to educate my patients about their treatment options and guide them through the cancer journey of diagnosis, treatment, and survival. Cancer diagnoses often leave patients feeling isolated and neglected, and I want them to feel empowered by the education I provide to make choices about their care. I often use humor to help my patients deal with fears and anxiety. After one of my patients told me she had not laughed since she had been told she had cancer, I knew humor was a necessity. I want to build a trusting relationship with my patients. When not at work, I enjoy spending time with my English bulldog Rex, family, and friends.
