Aubuelo Fierro was born in a suburb of Mexico City and immigration to the United States and formed a business, Fierro Ceramics, that made ceramic kit ware. He would make each piece by hand and take the time to make sure each piece was perfect.

At one point he married and had at least one child, a son, who would inherit the family business and turning in a machanical run kitchen ware empire, sacrificing quality for quantity. This was something he disagreed on and the two had a falling out.

When his grandchild was born he was the only one to accept Alex for who she was and the two developed a close bond. However he died by the time Alex was fourteen.
