Marcus Walker told me that he died. “Died, died,” he said, with emphasis.
Only through the grace of God is one of the greatest scorers in Kansas City high school basketball history still alive to recount his all-too-real brush with death.

On Aug. 15, his heart stopped and he had to be resuscitated.
“I checked out,” Walker said.
I’ve written before about the O’Hara High School graduate who in 2005 was the leading scorer in Kansas City prep history. He’s a basketball trainer with a passion for youth sports and the development of young athletes. He is also a big fan of women’s hoops and has trained some of the best high school players in the country. Many of his clients earned college scholarships.
But none of that mattered in mid-August when Walker said doctors told him he literally died and came back to life.
“I am grateful, blessed and overjoyed to be alive,” Walker wrote in a social media post on Instagram. “God is truly great, a miracle worker, and I am living proof of his power.”

Walker said the experience was a wake-up call. He said he wants to focus mainly on raising his 7-year-old son, training kids, helping highlight girls basketball and sharing the knowledge and connections he’s developed as a professional basketball player and trainer.
In 2012, an enlarged heart forced Walker to retire from a pro career playing ball in Iceland and Italy, among other stops overseas. Two years later, he started helping players develop their basketball skills here.
“Sometimes people hoard the info and the connections,” he said. “I don’t.”
Walker’s Grindhouse Basketball is one of the sponsors of the first St. Teresa’s Academy Stars Showcase, a girls high school basketball showcase this weekend featuring three teams touting some of the best players in the area and country. He used his vast network and worked with coaches and administrators at each school to make the event possible.

St. Teresa’s Academy was scheduled to host St. Louis’s Mary Institute-Country Day School on Friday. Saturday’s matchup features MICDS against Olathe North. Four of the best players around will take part, including Olathe North’s Asia Lee and Jordyn Haywood of MICDS.
Lee has committed to play college basketball at Florida State, and Haywood was a member of the 2025 USA Women’s U16 National Team and is considered a Top 5 player in the class of 2028.
Olathe North’s Daliyah Williams, the top-rated player in Kansas for 2028, and Division I recruit Jazlyn Rhoades of St. Teresa’s will be featured as well.
The weekend promises to be the first of many showcases featuring women hoops, Walker said. God willing, he added.

“Having events like this in Kansas City will give these kids a chance to be seen by college coaches,” Walker said.
Walker’s role in KC BB history
Alonzo Williams is the girls basketball head coach at Olathe North. He’s worked with Walker at the grassroots level and on this event. Thanks to people like Walker and others dedicated to kids, Williams said he’s witnessed the evolution of the girls basketball scene here over the last decade and the growth has been noticeable.
“I believe in the last 8-9 years the girls’ game has risen to a very high level,” Williams wrote in a text message.
Kansas City has been represented on a national level by many outstanding women hoopers over the years, Williams said.

Local players such as USA Basketball’s Jada Williams of Blue Springs and Park Hill South’s Addison Bjorn are among the players that has helped this city earn its respect on a national level, Williams said. Many of them worked with Walker, he said.
“That top tier talent comes from not only our region but Kansas City,” Williams said. “Usually if a girl makes it from KC, they have gone through the Grindhouse gym.”
Williams described Walker as a great ambassador for women’s hoops. The showcase Walker helped put together at St. Teresa’s is just the latest example that illustrates that passion, Williams said.
“Marcus does such a great job developing these young ladies from an early age teaching them the game he loves so much,” he said.

St. Teresa’s is coached by Kiera Hardy, a former high school and college standout and one-time WNBA draft pick. Last year, Hardy led the school to the Missouri Class 5 state championship game, a loss to first place Life for Life Academy in St. Louis. The Stars are locked and loaded for another deep run in the state playoffs, but early into a new season, St. Teresa’s is focused on the task at hand this weekend: working with Walker and others to highlight local girls basketball, Hardy said.
“Kansas City has unbelievable talent,” she said. “Talent that at times is not properly recognized or appreciated. I want for Kansas City girls high school basketball to be the talk of the town, the place to be on game days. We have so much talent, generational talent that deserves their appreciation while they are here, not when they are somewhere else.”
She described Walker as a brother-like figure in her life. She gave Walker the proverbial flowers many in the local basketball community have given him since this past summer’s health scare.
“Marcus is a brother to me,” Hardy said. “His importance to Kansas City and women’s basketball is tremendous. The support, recognition and commitment he has to putting women’s basketball on the map is unmatched. The love for the game and every player he comes in contact with is life changing. I am so thankful for him and all that he does for the community and basketball.

“God has a purpose for his life, and he is living out his mission through Grindhouse basketball.”
Health over hoops
At 39, Walker is relatively young. While he is not yet back training young athletes, he is still involved in community service. Last month, he hosted a Thanksgiving Day food drive for families in need. This weekend, at the showcase at St. Teresa’s, he’ll take a low-key approach to the event and maintain a low profile, he said. He participates in cardiac rehab — “just a series of exercises I was already doing” — but remains committed to developing young athletes.
After dying and coming back to life — his words, not mine — Walker said he is laser-focused more than ever on what’s important.

“My health,” he said.
He added that he plans to use his experience and influence to raise awareness to the importance of a healthy heart.
“Heart health is not talked about enough,” he said. “I’ve been doing physical exams my whole life but to have heart problems and not understand it. Having the knowledge can help you avoid it. People have to be locked in with their own health.”
