Relying on his background as a camp counselor, Dr. Crigger makes his patients active participants in their care whenever possible, often through sketching their condition. He is a member of multiple professional societies, including the American Urological Association and the American College of Surgeons. A researcher and director of pediatric urology research, he has published more than 50 articles in major journals and contributed to over 20 book chapters on pediatric urology. Dr. Crigger’s research focuses on his passion for major congenital anomalies, particularly the exstrophy-epispadias complex, about which he has multiple projects spanning the basic and clinical sciences. Additionally, with extensive training in robotic surgery, Dr. Crigger serves as director of robotic surgery for pediatric urology. His team looks for ways to safely apply the robotic surgery platform, including single port surgery, when feasible. His philosophy in practicing medicine is simple: to “provide the greatest benefit through the most up-to-date and least morbid treatment options possible.” Regarding providing care for patients and working with families, his focus is singular. When talking with parents, he can often be heard saying, “I know that, whether I am performing surgery or offering my professional recommendation, I am caring for one of the most important people in your life. I take that responsibility seriously and will do my very best to deliver the highest level of care possible.” Videos Chad Crigger, M.D.Pediatric Urologist.
