Jerry Hancock used his background in chemistry to develop a method of flash-freezing ice cream using liquid nitrogen. He and wife Naomi opened the first Sub Zero Ice Cream in Orem, Utah, in 2004, using this technology to offer customers the chance to customize their ice cream by choosing their milk base, flavors, mix-ins and texture. Sub Zero also offers a liquid nitrogen science education program that can be brought to schools.

Aerum Mahmood is the local franchise owner.  She takes great pride in bringing Sub Zero to her hometown of Pearland.
