Cooman grew up in Suriname in a family together with four sisters and one brother. When she was eight, the family moved to Rotterdam in the Netherlands. She started to play soccer and soon got the nickname "Miss Pele". At sixteen, she was discovered to be a very good sprinter during a sporting event at school; thus she began a career in athletics. Three months later, she competed in the European Youth Championships in Utrecht and finished seventh in the 100 metres sprint. Shortly after, she set a sprint record in the youth category. At seventeen, she won the Silver medal in the National Championships. After graduating secondary school she turned professional with Henk Kraaijenhof as trainer.
