Ico Humić
For over 40 years, Ico Humić has worked at the highest levels of professional tennis — coaching ATP & WTA-ranked players including Marin Čilić (ATP #3) and Marta Kostyuk (AUO U18 Champion), founding Tennis Academy Široki Brijeg, and building the most comprehensive tennis methodology ever created.
His approach was shaped at the world's biggest junior and senior tournaments, where he personally approached the greatest coaches, learned from them, and systematically built what would become the HTE system. Every chapter, every drill, every principle in this platform has been tested at the elite level.
