At his introductory news conference, Celtics No. 3 overall pick Jayson Tatum was accompanied by his parents, Brandy Cole-Barnes and Justin Tatum.

Jayson was raised primarily by his mother, who earned her law degree despite having him at age 19. Justin developed a strong bond with his son years later and they share a unique basketball relationship.

Jayson played at Chaminade College Prep School in St. Louis, while his father coached at his alma mater, Christian Brothers College High School. Both schools are members of the Metro Catholic Conference, meaning the Tatums faced each other twice a season during Jayson’s high school career.
