Brandon Hinson, ATC, ITAT - Metabolic Testing Administrator

Brandon received his bachelors degree from Grand Canyon University in Athletic Training. While at GCU, he had the opportunity to work with many sports teams in his clinical rotations. Brandon worked with ASU baseball, GCU soccer and volleyball, all of the teams at SCC, Sunnyslope High School, and Apollo High School. After graduating and receiving his certification and licensure as an Athletic Trainer, Brandon received training as an Emergency Medical Technician. His focus at the time was solely emergency and acute care for the athletic population. Shortly after, Brandon went on to pursue a certification as an ImPACT Trained Athletic Trainer as well. He began focusing on concussion recognition and management. Brandon practiced in a Physical Therapy setting as well as at a local high school for three years after that before making his transition into Advanced Metabolic Testing.

It was these experiences and meeting Anna and seeing how her company operated and their goals for patient outcomes that drove Brandon towards preventative medicine and working with Sparks Systems. He has loved it every day since! Brandon is here because he hopes to see this phenomenal program implemented across the nation for all populations. Preventative medicine that truly changes lives without medication is a rarity and Anna has got a good one!
