## Personal life

Sijsling grew up in Amsterdam, where his Serbian mother tried to instill her love of sports in her son. He played all kinds of sports as a young child, street football, basketball, and tennis. He even studied ballet.
He started playing tennis at the age of five with his parents, studying at the Amstelpark tennis school. By the time he was 12, tennis was clearly his sport. He was chosen for the Dutch national youth team. He won the Dutch under-18 championship twice and was runner-up at the European under-18 championships in Switzerland.
He received his diploma from the Vossius Gymnasium and began to play on the Futures and Challenger tours in 2006.
He was coached by Dennis Schenk.
