Early Life and Background
Olivier-Maxence Prosper grew up in Montreal, Quebec. His father, Gaetan, moved to Montreal from Haiti as a child, while his mother, Guylaine, also raised him in the same city.

Prosper initially attended L’Académie Ste-Thérèse, a school that did not have a basketball team, which limited his early organized opportunities. The absence of a school program pushed him to look elsewhere for competitive basketball.

Path to Basketball
When Prosper was 16, he enrolled at Lake Forest Academy in Lake Forest, Illinois, where he began playing high-level organized basketball in the United States. He later transferred to the NBA Academy Latin America in Mexico City, Mexico, to finish his high school career and develop against international competition.
Prosper was rated a four-star recruit coming out of high school and committed to play college basketball at Clemson. That path marked his first step into NCAA Division I competition.
