Keeler Approaching Milestone Win Amid Final Season of Legendary Tri-unity Career

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.”

Hoping to be 'Hardly Noticed,' 50-Year Official Allen Certainly Recognizable, Respected

Editor's Note: An extended version of this article appeared originally in the Cadillac News in March. Since then, Allen has been inducted into the Basketball Coaches Association of Michigan's Hall of Honor in October and is wearing the striped shirt again this basketball season, officially his 50th year.
CADILLAC – Bill Allen’s story is similar to that of many area sports officials, particularly those officials who have been active for many years.
A background in sports, typically playing team sports while growing up, combined with a desire to continue to be involved after high school or college, coupled with an inner urge to be part of the solution – these characteristics find a natural outlet for those brave souls who choose to be officials. and these traits are nearly always part of the make-up of the officials who receive high grades for their efforts and serve capably for many years.
Allen, of Cadillac, would not say this about himself. But he is one of those officials whom coaches are glad to see on the floor because they know they’re getting someone who will be fair and consistent. The same could also be said of Allen when he was umpiring, though he doesn’t work the diamonds anymore.
As Allen can tell you as he enters his 50th year wearing the striped shirt on the hardwood, officiating is a demanding vocation – and it is rewarding at the same time. It requires the right temperament as well as an above-average level of mental and physical fitness, especially as age makes its inevitable demands. It requires the ability to make decisions quickly, sometimes under very stressful conditions. It requires the ability to face criticism, sometimes expressed loudly or very loudly. It requires the ability to be a peacemaker at times and also the willingness not to hold grudges or become petty.
For those like Allen who have what it takes, those who are up to the challenges and the rigors that officiating requires from an individual, there is a deep satisfaction in knowing they are making a positive difference.
“I think that’s a common thread among all the officials, whether it’s basketball or baseball or softball,” Allen said. “You obviously want to do your best, but you want to manage the game in a way that helps it to flow the way it should flow and enables everyone, the players and the coaches and the fans, to get the most out of it.
“It’s an old cliché but it’s true: The best officials are the ones you hardly notice. If you can officiate a game and walk through the crowd afterward and no one recognizes you, then you’ve probably done your job pretty well that game. That’s what every official strives for.
“You’re never going to get every call right, and you have to be willing to accept that going into it,” he added. “But you know the rules and apply the rules the best you can, you put yourself in the best position to make the calls, especially in basketball, and you call it the way you see it.
“Are you always right? No. But if you put yourself in the right position and make the call you believe is correct, you can live with that and normally the coaches can too, even if they’re angry about a particular call in the moment.”
Allen, like most officials, was an athlete himself growing up in Traverse City and playing multiple sports for what was then known as Traverse City High School, the largest high school in Michigan in the early 1970s. By his own admission, he wasn’t one of the top stars in basketball and baseball but he was a good, reliable player for his coaches and a dependable teammate who loved the atmosphere of the arena during each season as well as the sense of achievement that the act of competing brought out in him like nothing else.
“I was pretty athletic growing up, but not a great athlete at Traverse City High School,” he said. “I was good enough to make the teams, but I wasn’t what you would call an impact player. A lot of officials have the same kind of background as mine. Maybe we weren’t the greatest players, but we still enjoy sports and we like being part of the action.”
It was during his final two years at Michigan State during the mid-1970s that Allen received his start in officiating.
“In my junior year at Michigan State, one of the fellows I roomed with did assignments for the intramural programs at the college,” he said. “Everything from touch football to basketball to slow-pitch softball. He told me to take the officiating class and he would assign me to games, and that’s how it all started 50 years ago.”
Allen jumped into the world of officiating eagerly with both feet, working a sporting event “nearly every night” at MSU.
“I would go to school during the day, ref at night, and do it again the next day,” he recalled.
“There were so many contests, maybe thousands, that I got to work with a number of other officials. Tim McClelland, who later became a Major League umpire and made the illegal pine tar bat call against George Brett, was a colleague back then. It was a lot of good experience and good mentoring and laid a great foundation for what turned out to be ahead.”
Allen initially earned a degree in criminal justice, graduating from Michigan State University in 1977, and worked in the field of corrections for a period of time before his love of baseball and a sense of personal confidence in his potential to officiate at a higher level prompted him to attend a school for prospective umpires in Daytona Beach, Fla.
That didn’t quite work out, but Allen was not deterred. He changed his career plans from criminal justice to education, and the switch would also lead to abundant opportunities for officiating down the road not just on the baseball and softball diamonds but the basketball court as well.
“When I didn’t get picked (for umpiring), I went back to school to earn my teaching certificate and a graduate degree in history with the goal of becoming a teacher at Cadillac,” he explained. Allen’s wife Sue already was employed as a teacher with the school district.
Bill’s goal at that point was to join Sue as a member of the faculty, as a social studies teacher, and that’s just what happened. Bill served for 26 years in the classroom before retiring along with Sue 12 years ago.
“I viewed Cadillac schools as a great organization to work for as a teacher before I got hired there, and I was right,” he said. “I wouldn’t trade my years at Cadillac for anything. Susie and I both thoroughly enjoyed our years there.”
In conjunction with teaching, Allen continued to officiate basketball in the winter and baseball in the spring and summer. He umpired a lot of men’s summer league softball games through the years and grew to love in particular working the games under the lights at Cadillac’s Lincoln Field.
He also became a registered official with the MHSAA and has continued in that role, though he decided to hang up his umpire cleats a few years ago.
“I registered with the MHSAA while I was still in Lansing,” he said. “The first place I ever did a sanctioned event was in Perry, Michigan. I had barely enough (umpiring) equipment and I’m sure I looked like a real yahoo out there, but I got through it.”
After coming to Cadillac, Allen met Dave Martin, who was an active official and a fellow teacher at Marion, and Martin became his first “crew chief.”
“They needed some JV officials and I got signed up and was off and running,” Allen recalled. “That’s how you got into it back then. You found a crew and the crew chief assigned you some games, and you were evaluated. As long as they liked you and liked what you were doing, they kept you around.”
Allen expressed admiration and appreciation for Martin and also the late June Helmboldt from Lake City, another crew leader “who had a great perspective on the game.”
Allen served as a crew chief himself for a long time and has built rewarding relationships with fellow officials through the years. He has worked many games with Penny McDonald of Cadillac, another longtime official who has earned much respect for her consistency and quality of work in multiple sports over the decades. Allen, in a reversal of roles, is the one receiving assignments from McDonald these days.
Bill Bartholomew is another longtime officiating partner with whom Allen has worked many games over the years and for whom Allen has great respect. This school year, in fact, marks Bartholomew’s 51st year as an official. There are a few others from northern Michigan who have stood the test of time and have passed the 50-year service milestone, such as Paul Williams of Mesick, Tom Post and Mike Muldowney of Traverse City, Tom Johnson of Gaylord, and Dan Aldrich of Charlevoix. All of these, Allen said, are a credit to the craft of officiating and have earned the respect they receive.
Allen also has fond memories of working frequently through the years with Don Blue of Falmouth and Jill Baker-Cooley of Big Rapids, who was chosen for the MHSAA’s prestigious Vern L. Norris Award in 2018.
“I was there when Don and Julie and Penny all got their start in officiating, and they all found their skill set and became excellent officials,” Allen said.
Bill is included in the 50-year milestone group of basketball officials now that the 2025-26 season is underway. He is pleased that he has been able to maintain his longevity; as to the future, he is ready and willing to keep going.
“As long as I’m healthy and can do it properly, I hope to continue,” said Allen, who remains physically fit, jogging regularly along with activities including downhill skiing in the winters and golf during the warmer months.
“I’ll know when it’s time to step aside. When I can’t see well enough to judge the baseline and need to rely on my partners more than I should, then it’s time to hang up the whistle and let the younger ones take over. I hope that’s not for a while though.”
