“I joined ARM-NET because it is amazing to be part of a team of clinicians, who are all so dedicated to treat patients with an anorectal malformation. Also, the fact that we create a database with large number of patients means that we can perform better research. It is our goal that this research and joined knowledge will improve the care of our patients.”
