John Oliver is making history—and coming full circle.
This summer, the 29-year-old Chicago Heights native became the first Black men’s head basketball coach in the 67-year history of Marian Catholic High School. But for Oliver, a Marian alum and former player, it’s about more than just a title.
“It’s a full-circle moment,” Oliver said. “To walk back into the gym where I grew up, and now lead it, is surreal. But I’m ready.”
Oliver’s appointment is monumental not just for the school, but for the larger community. Black men comprise just 8.8 percent of all head coaches in boys high school basketball nationally. His hire marks progress—and representation—for a new generation of student-athletes.
Those who know Oliver best say he’s the right man for the job.
“John has always taken on challenges. He never let anything stop him,” said Genice Leavell, Oliver’s first formal coach. “He never backed down—on the court or off. I’m not surprised at all he’s coaching now. It’s in his blood.”
Indeed, sports runs deep in the Oliver family. His grandfather played baseball in the Negro Leagues. His grandmother once dropped 30 points in a basketball game—while pregnant with John’s father. His father, who played basketball and football at Northeastern Illinois University, was John’s first coach, keeping him active in both baseball and basketball from an early age. From the park courts of Ogden Park to the gymnasiums of Collegeville, Minnesota, Oliver’s path has been anything but typical.
He was born without his left hand. But rather than viewing it as a disability, Oliver embraced it as a challenge to overcome.
“I’ve never called it a disability,” he said. “I held myself to the same standard as anyone else. If anything, I worked harder. I didn’t want sympathy—I wanted results.”
Those results showed early. Under Leavell’s mentorship in the Matteson League, Oliver quickly earned a reputation as a competitor. He later played at Marian Catholic, then took his talents to Saint John’s University in Minnesota, where he competed for four years at the Division III level.
He wasn’t chasing the NBA. From early on, Oliver knew his basketball journey wasn’t about professional glory—it was about pushing limits and inspiring others.
“I used basketball as my passport,” he said. “It took me out the country for the first time. I got to travel, I took my dad overseas. I used it to challenge myself, and when I hit those goals, I asked, ‘What else can I do?’”
Coaching wasn’t initially in the plan. After college, Oliver and a friend started a nonprofit, The Cause International, focused on service work in under-resourced communities. He was set to move to Los Angeles to pursue that full time—until fate, and a few drinks, intervened.
While working in the University of Minnesota’s athletic department as part of a communications internship, Oliver had a chance meeting with then-basketball coach Richard Pitino, who was impressed by their conversation and offered Oliver a graduate assistant coaching role.
Just like that, Oliver was on the sidelines—earning his master’s degree and coaching top Division I athletes. His coaching mentors included both Richard Pitino and his father, the legendary coach Rick Pitino, who was often in the gym during practices. Oliver soaked it all in.
“I was a sponge,” he said. “I learned about preparation, about systems, about how to read players—and about the business side of it, too.”
As one of the youngest members of the Minnesota coaching staff, Oliver found himself working closely with athletes who were his peers in age—and in some cases, former AAU teammates. Far from being a hindrance, this proximity earned him respect.
“I think the players looked at me like, ‘Would you do what you’re asking me to do?’” Oliver recalled. “Because I had just been in their shoes, there was mutual respect. They knew I understood the grind. That made it easier to communicate and connect with them as a coach.”
The experience shaped how he would lead. But the transition from the Big Ten sidelines to high school coaching brought a different set of challenges.
“At the college level, you’re preparing players for pro careers and running tightly structured systems. At the high school level, I’ve had to adjust my approach,” he said. “Here, it’s more about development, consistency, and meeting kids where they are. You can’t just coach systems—you have to coach the individual.”
After Minnesota, Oliver returned home to Marian Catholic as an assistant. He also became a P.E. and health teacher at Chicago Heights Middle School, working with younger students—some of whom have since followed him to Marian.
“I see myself in a lot of them,” he said. “I want them to know they belong here. That this program, this gym, this space—it’s for them.”
As a head coach, Oliver brings a flexible, player-first philosophy shaped by personal experience. He emphasizes effort, adaptability, and building strong mentor relationships with his players.
“I want to understand who I’m coaching before deciding what kind of coach I need to be,” he said. “You have to meet players where they are and pull the best out of them. That’s what great coaches do.”
A core part of that philosophy is how players respond to adversity.
“Mistakes will happen. Basketball isn’t perfect,” Oliver said. “What I watch for is how a player reacts—if they miss a shot, do they pout or hustle back on defense? That tells me more than any stat line.”
Coach Leavell agrees.
“John never gave me a problem. He was one of my prize students,” she said. “He’s going to be great for those young men. They’ll want to play for him, and that’s what matters.”
Oliver’s coaching staff includes former players and a standout female coach, Danielle King, who played at Bloom and Marquette before coaching at Tennessee State. He wants his players to see excellence in many forms.
At the center of it all is family. From his parents and grandparents to a legacy of athletes going back generations, Oliver credits his family’s support for getting him where he is today.
He’s already seen the impact of his appointment.
“When I told other Black alums I was interviewing, the excitement on their faces said it all,” Oliver said. “It’s not just about me. It’s about all of us.”
With high expectations, an experienced staff, and a mission to restore excitement in the program, Oliver is ready to write the next chapter in Marian Catholic’s story.
“I want people to feel something special when they come into our gym,” he said. “This is home. And we’re just getting started.”
