Greet the Kotzian family from Thornton, Colorado. This family, like other people with dwarfism (a rare genetic disorder of bone growth), has worked very hard to overcome social and physical barriers and can now live normal lives. The Kotzians work with Little People of America. It?s the only dwarfism support organization that helps little persons across the US. They went through a lot as there are many Americans who treat little persons like a circus act.
