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.
