WYOMING – Mark Keeler has spent four decades coaching boys basketball at Tri-unity Christian High School.
And while he has many stories that he shares often, one of his favorites comes from the beginnings of the program.
“We didn't have bleachers in our gym when I first started,” Keeler said. “I would make my boys set several rows of chairs up so people could watch our games. And then they eventually added bleachers that were donated by the church.”
Keeler’s teams have been filling up the bleachers since he took the reins for the 1983-84 season, and he has built the program into one of the most successful in the state.
Now, as he leads his team through the opening month of his 38th and final campaign, Keeler is nearing a rare milestone only achieved by a few. He is expected to soon become the fourth coach in MHSAA history to reach 700 wins.
Tri-unity is 3-1 this winter, making Keeler a combined 697-217 coaching the Defenders. Roy Johnston is the winningest coach in state boys basketball history with 833 victories earned during stints at Yale, Howell and Beaverton before retiring in March. He is followed by longtime River Rouge coach Lofton Greene (728) and Clarkston’s Dan Fife (703).
“It's a statement of longevity with these men,” Keeler said. “All three of them were very successful at the schools they were at and most of them spent a long time at one school, just like I’m doing now. I’ve never coached anywhere but Tri-unity, and that is quite a privilege to have been a part of this school.”
Keeler reached 697 wins with last week’s nonconference victory over Wyoming Kelloggsville and can move closer to the milestone with another Friday night against Grandville Calvin Christian. The Defenders then play East Grand Rapids and Grand Rapids West Catholic, respectively, at the Cornerstone University Holiday Classic at the end of the month.
Keeler, who retired from a 40-year teaching career two years ago, started coaching in 1983-84 when Tri-unity had only an eighth and ninth-grade team. After two seasons of playing subvarsity, the school formed its varsity team for the start of the 1985-86 season, with Keeler at the helm. After three seasons with the varsity, he took a break from coaching (but continued teaching and serving as athletic director).
“I had to get my priorities right with the Lord,” Keeler said. “I was trying to do too much and lost focus, and it was something that needed to be done. I look back, and it was something that set me up for the rest of my coaching career.”
Keeler returned for the 1990-91 season and has been at the forefront ever since. He has guided the Defenders to six state championships, including last year’s with a victory over Mount Pleasant Sacred Heart in the Division 4 Final. Tri-unity also has won titles in 1996, 2002, 2006, 2011 and 2022, while finishing as Finals runner-up six times.
Keeler’s teams also have reached the Semifinals 15 times, won 19 Regional championships, 26 District titles and 22 conference championships. His players have filled Class D and Division 4 all-state teams for years, with surely the best-known 2000 grad Chris Kaman – who went on to play at Central Michigan and 13 seasons in the NBA – and Brandon Voorhees, who led Tri-unity to the 2002 title as a senior, went on to CMU and then Park University in Missouri, and played professionally overseas.
“I’m so glad that I’ve been able to just be here this long,” said Keeler, who was inducted into the Basketball Coaches Association of Michigan Hall of Fame in 2016. “I love Tri-unity. My wife taught there, we met there, and my daughters went all the way through and graduated from there, so it's always been a part of my life. There's been so many quality people that have been there along the way.
“I've been very blessed to have had so many quality players and parents and coaches. It’s amazing when I look back at all those that have been a part of the program.”
Keeler, a man with a strong Christian faith, could’ve gone elsewhere during his career, but believed he had a calling at Tri-unity.
“I've had some opportunities to move on and go to different places, but whenever I prayed about it I always thought that this is where the Lord wanted me and that's always my priority,” Keeler said. “I want to please him first, because as a Christian that's my priority. I just thought this is where he placed me, so I’m going to set roots and do the best I can.”
Tri-unity senior guard Keaton Blanker, one of two returning starters on this year’s team, is excited to see his coach reach such a prestigious milestone.
“It’s the perfect scenario for him with this being his last year and getting to 700 wins,” Blanker said. “He’s going to leave his mark, and it’s well deserved. Being a small Division 4 school, he’s helped to put the program on the map and I remember growing up and watching his teams win state titles. I was waiting for the opportunity to play for him so I could help do the same thing.”
While Keeler is grateful for the unbridled success of the program on the court, creating lasting relationships with his players off the court and helping them grow in their faith has been equally gratifying.
“I know without a doubt that the Lord has blessed our program.” Keeler said. “There are a lot of great coaches out there that are probably better at Xs and Os than I am, but I think I’m a strong motivator and build good relationships with the players and get to know them.
“I let each player know that I want them to grow in their walk with the Lord, and that's where my priority is. To be an influence toward Christ, not away from Christ.”
Past Tri-unity standout Brent Voorhees, who has been Keeler’s assistant coach the last several years and will succeed him next season, said Keeler has never changed his approach to the game.
“Coming back to coach with him, the one thing that stands out is he doesn't waver on his principles,” Voorhees said. “A lot has changed in the sport in terms of analytics and how coaches attack things, but he has definitely stayed firm in his approach that it’s defense first and he preaches the team aspect. It’s never about an individual.
“He doesn’t let anything off the court distract him from goals. He's really good at keeping the goal in front of the guys. He keeps them focused on the goal of winning state championships and also becoming great, young Christian men in the community, which is what he stands for and always comes first.”
The Defenders graduated eight players from last year’s team, but Blanker and senior Joey Mellon are back with several newcomers as they bid to send Keeler out with one more title at Breslin Center.
“I enjoy putting them together and getting them to mesh as a team,” Keeler said. “For me, I have learned that defense wins championships. The old adage that offense wins games, but defense wins championships ... I so believe that with all my heart.”

Harbor Beach Motivated by Past, Focused on Present in Chasing Future Goals

Andrew Kabban and his Harbor Beach boys basketball teammates know how quickly a good thing can end.
After going 19-3 and dominating the Greater Thumb Conference East a year ago, the Pirates had their bubble burst with a buzzer beater in the Division 4 District Final against Cass City, a team they had defeated by 13 a month earlier.
“We’ve kind of had last year stuck in the back of our minds,” said Kabban, a junior point guard. “We have a lot of returning players, we only lost two guys last year, so we all remember what happened last year. We’ve built on that experience, and we’re trying to use our experience to our advantage.”
That experience has allowed the Pirates to hold onto last year for motivation while focusing on what’s directly in front of them, and it’s working. Heading into Wednesday night, they are 17-1 this season, including a perfect 9-0 in the Big Thumb Conference Black. That includes wins over Division 2 Croswell-Lexington (12-5) and Millington (16-2). Their one setback was a 2-point loss against Yale (18-1), the No. 9 team in Division 2.
Of course, they’ll need to keep doing that into March in order to feel as though they’ve truly grown.
“Even with me, I’m a team captain, and sometimes I can catch myself talking about (a bigger game against) Millington, for instance,” junior Benson Harper said. “I just have to remember that we have to take care of business first and stay focused. If we don’t stay focused, something bad can happen to us.”
It becomes easier to maintain that focus when everyone’s on the same page, and for this version of the Pirates, they’ve had plenty of time playing together to get there.
The majority of the roster – nine players – comes from the junior class, with three seniors joining them. That’s a group that has been playing together since elementary school in multiple sports, and winning plenty along the way.
“We started playing together in second grade,” Harper said. “We’ve just been playing ball together forever. We lost one game in seventh grade, then went undefeated in eighth grade. … We’ve just been winning together, and when you see everybody every single day, you build a bond with them, not even just in sports.”
That consistency spans sports and even the coaching staff. Head coach Ron Wruble is also the defensive coordinator for the football team, and the Pirates were 11-1 this past season and 9-2 the year prior.
“These kids, they’re obviously playing football together and playing basketball now, and most of them hang out together, too,” Wruble said. “There’s a lot of camaraderie in the group, and I think they just enjoy being together.”
There was one season where they weren’t all together, however, as Harper was moved to the varsity squad as a freshman. He wasted no time becoming a go-to option for the Pirates, and earlier this season eclipsed the 1,000-point mark.
“He started for us as a freshman, and you can just see his development over the last three years,” Wruble said. “He’s gotten bigger, stronger – his skill set was at the varsity caliber as a freshman, but it’s just been moving up from there.”
In his first season, however, the Pirates were an uncharacteristic 7-12. Harper was happy to be playing at the varsity level, but certainly missed his classmates.
“It was definitely tough, because I was so young and so used to playing with them,” Harper said. “We had kind of a crappy freshman year, and I wasn’t used to losing. But I was also happy to see them winning (on the junior varsity level), and they dominated, too.”
When they all came together again at the varsity level, the success was almost instant. That came as no surprise to Wruble.
“It’s just the general makeup of the team – there’s a big core of kids that are gym rats,” he said. “They live in the gym and the weight room.”
That’s led to a high level of competition in practice, as Wruble praised the depth of his team. It also has the Pirates dominating against a schedule that was built to prepare them for the postseason.
“We try to schedule teams that are going to be the better programs, and that really helps us in the long run,” Wruble said. “We’re coming through the second time around with our conference opponents, and hopefully we can play well and take care of business there.
“Obviously, our District loss last year was a heartbreaker. We lost the District championship at the buzzer with a 3-point shot, and that’s still sticking in the minds of our kids, and they want to get back there and avenge that then, and hopefully move on from there. But it’s going to be one game at a time, and we even break it down further than that: one play at a time. A play in the first quarter had just as much meaning to the end of the game as a play at the end of the game.”
That message – with the help of past experiences – is coming through loud and clear.
“The goal is to win a District and win a Regional,” Kabban said. “The regional is not out of reach for us. But we have to win the District first. We have to win our league first. But we know that we’re capable of doing whatever we put our minds to.”
