Hunter Barnhill

Hunter Barnhill
Hunter Barnhill is an O2X Resilience Specialist and a former U.S. Air Force pilot with over 700 hours logged in the B-52H Stratofortress, and over 600 hours in the T-6A Texan II. As a B-52H pilot, Hunter led his crew in accomplishing a variety of missions. Missions including nuclear deterrence, close air support, air-to-ground, direct attack, and counter-drug. In 2015, Hunter volunteered to be an Instructor Pilot and was thus tasked with the crucial and vital role of instructing and producing the Air Force’s next generation of highly skilled and capable pilots. On Easter Sunday 2017, Hunter suffered a seizure caused by a previously undetected brain tumor which required immediate surgery to remove. Hunter was subsequently diagnosed with malignant brain cancer, thus cutting short his military aviation career. The diagnosis led Hunter to develop a deeper respect for resiliency and a new-found passion for teaching others how to implement the life-saving and life-enriching skills into their own lives: “I had received hundreds of hours of resiliency training from the Air Force for the purpose of instructing other Airmen. Even in passing along those resiliency skills to others, I had failed to internalize and apply those skills myself, but that all changed when I received my cancer diagnosis.” The skills and techniques he once used to teach undergraduate pilots now enables him to teach and instruct thousands in developing and building their own resilience. Hunter resides in Columbus, Ohio with his wife Crystal, son Nolan, and dog Riley. Despite being found medically unqualified to fly, his passion for aviation continues. He enjoys studying leadership, is a proud Ohioan, and a die-hard Ohio State Buckeye athletics fan, especially football and hockey. Most of all, he loves seizing opportunities to strengthen his faith and spending quality time with his family.

His approach pairs that practical understanding with Cognitive Behavioral Therapy and other empirically supported treatments.
