Tan Xu Teng — known to his students as Coach XT — began his tennis coaching journey in 2001. At that time, he was an undergraduate at the Law Faculty NUS. There, he saw that Singapore needed top-level tennis coaches to raise coaching standards and elevate the national game.
Consequently, he set his sights on attracting elite players with proven regional success. In 2007, he founded Tennis Allegiance Group (TAG) International to make that vision a reality.
