Born on February 8, 1970, in Chesapeake, Virginia, to Alonzo Mourning Sr and Julia Hadnot, Mourning’s talent on the high school basketball team was undeniable. His junior year saw him help lead the team to a state title, and his senior year was marked by impressive averages of around 25 points, 15 rebounds, and 12 blocked shots per game. His exceptional performance earned him the title of Player of the Year by USA Today, Parade, and Gatorade by the time he graduated from Indian River High School in Chesapeake in 1988.

Mourning then attended Georgetown University in Washington, D.C., where he played on the Georgetown Hoyas basketball team coached by John Thompson. He also played alongside future NBA star Dikembe Mutombo.
