Reflecting on His Past, Bryan Mines a New Future

Bryan’s family is no stranger to mining. Born and raised in Globe, Bryan grew up watching his father and uncles work at the Magma Copper Mine. The industry was volatile at the time, and Bryan’s father was laid off three different times. Wanting a more stable path for his son, Bryan’s father encouraged him to do anything else for a living. Bryan followed that advice and decided to enroll at the University of Arizona, where he earned his Bachelor of Science degree in economic development.

Other days it looked like robotics kits in classrooms, filling sandbags, or youth baseball teams taking the field.
