関根 大輔 Daisuke Sekine

Originally from Saitama Prefecture, he now works as an athletic trainer at American University. After graduating from high school, despite never having owned a passport or even been on an airplane, he moved to the United States to attend college. Before studying abroad, he had assumed without a doubt that he would return to Japan and find a job after graduation. However, he went on to pursue a master’s degree and has remained in the U.S. ever since, building his career as an athletic trainer across rehabilitation clinics, high schools, and universities.
