Our surgeons hold teaching appointments with the Mayo Clinic College of Medicine and Creighton University School of Medicine and are actively involved in the education of young urologists, surgeons and pediatricians. Through our research and publications in the field of pediatric urology, we are helping to advance medical care for children worldwide.
