When Danny Wong returned to Dunman Secondary School after graduating from the National Institute of Education in 2006, he was handed a daunting task.
The mathematics and physical education teacher, who had taught at the Tampines-based school while at the NIE as part of his curriculum, was asked by a colleague to help set up a girls' basketball team.
He had no coaching badges and could only rely on his playing experience when he was a schoolboy, but Wong agreed.
"I didn't expect to be involved with basketball when I came here," said the 35-year-old, who played the sport from secondary school to university.
To make the transition to coach, Wong turned to books and online videos.
Said Wong: "The teacher-in-charge of the boys' team at the time (Tan Jing Yang) was a close friend of mine and he asked me to set up the girls' team with him.
"We didn't have a lot of resources back then and, for the first few years, it was quite tough to really stand out from the pool of very good basketball schools."
After a series of top-four finishes in the East Zone competition, the big breakthrough came when Wong guided his first batch of girls to the B Division title in 2009.
It was Dunman's first basketball title.
It was the start of a golden run, as Dunman's girls' teams went on to clinch four more titles in the C and B Divisions, with Wong involved in three of them.
