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.”

Burt Lake Northern Michigan Christian Academy won its first District championship in boys basketball last week. Fruitport won its first since 1938.
Yale defeated Croswell-Lexington and Marshall defeated Battle Creek Pennfield in District Final matchups of teams that shared league titles. Ann Arbor Pioneer, Grand Rapids Catholic Central, Colon and Detroit Cass Tech all finished second in their leagues this season but won their Districts as well, defeating their respective league champions to advance to this week’s Regionals.
Districts offer every team new life and second chances – and after a week full of those, 128 hopefuls are only three more wins from booking a trip to Michigan State.

“Breslin Bound” is powered by MI Student Aid and based on results and schedules posted for each school at MHSAA.com.
Week in Review
The countdown of last week’s five most intriguing results:
1. Detroit Cass Tech 66, Detroit Martin Luther King 23 The Technicians (18-6) avenged a pair of regular-season losses to rival King (18-6) in a big way in this Division 1 District final after previously falling by seven points Jan. 21 and then 68-63 in the Detroit Public School League Tournament championship game on Feb. 15.
2. Rockford 83, Muskegon 70 The Rams (20-3) won this Division 1 District Final matchup for the second-straight season, ending Ottawa-Kent Conference Green champion Muskegon’s run at 20-3.
3. Hudsonville Unity Christian 60, Grand Rapids South Christian 39 This Division 2 District Final pitted the champs from the O-K Black and Gold, with Unity (21-3) adding to its 17-point win over the Sailors (20-4) from Dec. 12.
4. Colon 54, Mendon 47 The Magi (20-4) had finished second to Mendon in the Southern Central Athletic Association West after losing in overtime both times they faced the Hornets (22-2) during the regular season, but got past them in regulation in this Division 4 District Final.
5. Grand Rapids Catholic Central 44, Grand Rapids Christian 41 The Cougars (18-6) had fallen to Grand Rapids Christian (17-6) by nine points just 10 days earlier to lose the O-K White title to the Eagles, but rebounded to win a Division 2 District title for the third-straight season.
Regionals at a Glance
These could be among our most competitive brackets. Host sites are in bold:
DIVISION 1
Caledonia
Grand Rapids Northview (20-4) vs. Grandville (14-10)
Holland West Ottawa (13-11) vs. East Kentwood (21-2)
Grandville and West Ottawa deserve nods for reaching this week, the Bulldogs for avenging two regular-season losses to Hudsonville with a 49-37 District Final win and the Panthers as they added to a nice streak of four wins in five games by joining Grandville, East Kentwood and Rockford as one of four District champs from the Ottawa-Kent Conference Red. But the most anticipated matchup this week would see O-K Gold co-champion Northview take on the Falcons, who won that O-K Red that also will see all six teams finish with winning records this season.
Detroit Renaissance
Bloomfield Hills Brother Rice (19-5) vs. Detroit Cass Tech (18-6)
Farmington (12-12) vs. Warren Fitzgerald (18-6)
Brother Rice and Cass Tech have been in the statewide favorites conversation most of this decade, and although neither won its league this season it wouldn’t be shocking to see either playing at Breslin with an opportunity to win it all in two weeks. Only three of Rice’s losses were to in-state opponents – East Lansing (23-1), Rockford (20-3) and Detroit Catholic Central (17-6) – and Cass Tech’s six defeats came by a combined 21 points. Farmington has emerged after finishing fifth in the Oakland Activities Association Red and defeated Redford Thurston (20-3) to advance, and Fitzgerald has won 12 of its last 15 and claimed the Macomb Area Conference White title.
Kalamazoo Loy Norrix
Jackson (18-6) vs. Kalamazoo Central (20-2)
Kalamazoo Loy Norrix (16-7) vs. East Lansing (23-1)
Reigning Division 1 champion East Lansing has been stopped only once this season, by Grand Rapids Northview on Feb. 7. The Trojans also defeated Loy Norrix 78-50 two weeks ago, and last year downed Kalamazoo Central by 35 points in the Regional Final. The Maroon Giants are among the state’s elite again this season and perhaps even a step up from a year ago, with losses to only Detroit Martin Luther King (18-6) and Bloomfield Hills Brother Rice (19-5). The focus is on those two, but Jackson has won 11 of its last 12 games, and Loy Norrix has its most wins since 2011-12.
DIVISION 2
Fowlerville
Chelsea (18-5) vs. Marshall (19-4)
Lansing Sexton (22-2) vs. Michigan Center (20-3)
All of these teams are league champions, Sexton in the Capital Area Activities Conference White, Michigan Center in the Cascades Conference East, Chelsea sharing with two others in the Southeastern Conference White and Marshall as co-champion in the Interstate 8 Athletic Conference. Marshall downed the other I8AC co-champ Battle Creek Pennfield to advance and also defeated Michigan Center 64-50 on Dec. 13. Sexton defeated Chelsea by two points last season in their Regional Final and has been even better this winter with its only losses to Division 1 East Lansing and Lansing Waverly. Michigan Center bounced back from two losses to end the regular season, and Chelsea has three defeats by one or two points and shared the SEC White title with Division 1 teams Ypsilanti Lincoln and Jackson.
Manistique
Kingsford (16-6) vs. Cheboygan (18-6)
Ludington (22-2) vs. Gladwin (23-1)
Gladwin won the Jack Pine Conference overall championship and is riding a 23-game winning streak since falling to Sanford Meridian (17-7) in its season opener. The Flying Gs take on another league champion in Ludington, which won the West Michigan Conference Lakes and has lost to only Division 1 Traverse City West (16-5) and North Muskegon (22-2). Those two will play one of the most intriguing Regional Semifinals in any division, but Kingsford or Cheboygan also will be formidable Thursday. The Flivvers made the Division 2 Semifinals a year ago, defeating Ludington by 40 in the Regional Final along the way. Cheboygan has doubled its win total this season from two years ago and got through close games with Grayling and Ogemaw Heights last week to advance.
Owosso
Flint Hamady (16-6) vs. Frankenmuth (23-1)
Freeland (21-3) vs. Portland (18-5)
This group is a complete repeat of last year’s Regional that saw Freeland advance to the Quarterfinals by defeating Portland. Heading into this year’s bracket, Frankenmuth finished first and Freeland second in the Tri-Valley Conference Red, and Freeland handed the Eagles their only loss, 54-48 on Feb. 13, after Frankenmuth had won their first meeting 47-43. Hamady won the Genesee Area Conference Blue and advanced to this week with a 17-point win over Flint Powers Catholic (16-7). Portland finished second in the CAAC White behind Lansing Sexton (22-2) and has won nine of its last 10 games.
DIVISION 3
Cass City
Reese (15-10) vs. International Academy of Flint (18-4)
Sandusky (16-7) vs. Harbor Beach (21-3)
Harbor Beach has totaled at least 20 wins the last three seasons and reached the Regional Final a year ago, but must defeat a familiar opponent for a third time to take that step again. The Pirates won the Big Thumb Conference Black and Sandusky finished third – and Sandusky also had a win over Reese just two weeks ago. The Rockets emerged by upsetting Saginaw Michigan Lutheran Seminary (19-5) in their District Final and now must take on another league champion in IAF, which won the Genesee Area Conference Red. The Phoenix bounced back from a pair of losses to end the regular season to earn their second District title over the last three years, and all of IAF’s defeats came to opponents with at least 18 wins.
Clinton
Ottawa Lake Whiteford (21-3) vs. Onsted (22-2)
Jonesville (18-6) vs. Ecorse (18-5)
Whiteford/Onsted should be another Regional Semifinal with notable statewide interest as both are league champions – in the Tri-County Conference and Lenawee County Athletic Association, respectively – with only a handful of losses between them. Whiteford actually shared the TCC title but has won 11 straight games and lost only twice to in-state opponents. Both Onsted defeats came to Division 2 teams. Ecorse also is a league champion, in the Charter School Conference Silver, and only three years removed from a run to the Division 3 Semifinals. Jonesville was the runner-up in the Cascades Conference West and reached this week with two five-point wins in its District including a triple-overtime victory over Hudson.
Kingsford
Ishpeming Westwood (23-1) vs. Menominee (20-4)
East Jordan (22-2) vs. Elk Rapids (20-3)
This is another field of four league champs, starting with Western Peninsula Athletic Conference winner Westwood, which made the Division 3 Semifinals a year ago and defeated Great Northern Conference champ Menominee 55-52 on Feb. 6. That was one of three Maroons defeats against teams still playing this week, and Menominee is only two years removed from winning a Regional title. East Jordan won the Ski Valley Conference and defeated Mancelona (21-3) for the third time this season to win their District Final. Elk Rapids won the Northern Shores Conference and has lost to only Division 1 and 2 opponents. The Elks got past Northwest Conference champion Maple City Glen Lake by three points last week to advance.
DIVISION 4
Detroit Douglass
Detroit Douglass (17-7) vs. Allen Park Inter-City Baptist (21-3)
Whitmore Lake (17-7) vs. Southfield Christian (19-5)
Inter-City Baptist defeated Douglass in a Regional Semifinal a year ago during its run to Breslin and has lost to only Division 1 and 2 teams this season that all have won at least 17 games. The host Hurricanes also have lost to only Division 1 and 2 teams, all with at least 14 wins – and Douglass nearly made the PSL championship game before falling to Cass Tech in overtime of their semifinal. Inter-City Baptist won the Michigan Independent Athletic Conference Blue and has two victories over both Whitmore Lake and Southfield Christian, which split their regular-season series with Whitmore Lake winning the first game and the Eagles taking the rematch.
Hillman
Rudyard (14-10) vs. Pickford (23-0)
Burt Lake Northern Michigan Christian (16-7) vs. Hillman (21-2)
As noted above, Northern Michigan Christian is coming off its first District championship in this sport. The Eagles also have a win over Rudyard this season and a 23-pointer over Posen – which shared the North Star League Little Dipper championship with Hillman. That adds another level of intrigue to this bracket as Hillman and Posen split and Hillman lost their second meeting – although the Tigers already avenged their other loss, to Rogers City, twice including last week. Pickford has 27 and 29-point wins over Rudyard this season and is pursuing a second-straight Regional title after missing a trip to Breslin last season with a two-point Quarterfinal loss. Rudyard has won 10 of its last 13 games and in its District Final avenged a 20-point loss to Brimley from 10 days earlier with a two-point win.
Merrill
Fowler (22-2) vs. Baldwin (20-4)
Wyoming Tri-unity Christian (22-1) vs. Saginaw Nouvel Catholic Central (16-7)
This power-packed Regional starts with Tri-unity, the reigning Division 4 champion with its only loss this season to Division 2 Fruitport (21-3) on Dec. 20. The Defenders must first take on a Nouvel team that finished second in the TVC Blue and has won eight of its last nine games including 55-50 over Mount Pleasant Sacred Heart (18-5) in their District Final. And whichever team comes out of Fowler/Baldwin will provide a major challenge as well. The Eagles also ran into Tri-unity last year – in the Division 4 championship game, won by the Defenders 49-32 – and Fowler’s only losses this winter were to Division 3 Pewamo-Westphalia (22-2). Baldwin will do its best to prevent that rematch and is plenty capable after avenging an earlier defeat to clinch the outright West Michigan D League title while riding a run of nine wins over its last 10 games.
