IRONWOOD — Dennis Mackey made a big impact on generations of athletes at Gogebic Community College, so much so that college officials named the basketball court after him while he was still coaching.
Mackey retired from coaching in April after 38 years at GCC, 19 with the women and 19 with the men. Even after all of those years, and more than 500 wins, the memories and lessons from his playing days at Ewen-Trout Creek still resonate with him.
He was always doing something athletically, football in the fall, baseball in the summer, track & field in the spring. His home being basketball-centered E-TC – the tiny Upper Peninsula school with nine combined boys and girls MHSAA Finals appearances – hoops was always mixed in.
“Basketball was the winter sport, but no matter the season we always found time to get to the gym and shoot hoops,” Mackey said. “Whether it was during the lunch hour, after school, on weekends, or after practices, we seemed to gravitate to the gym for some action.”
And if they didn’t go to the gym, there were outdoor courts in Ewen, Bruce Crossing and Trout Creek to get shots up.
“Basketball was the main sport in those communities and probably is still to this day,” Mackey said. “Looking back now, I must say the experiences growing up playing basketball at E-TC was awesome.”
Mackey, a 1981 graduate, played on the varsity team all four years of high school. The Panthers lost in the Regional Final at Northern Michigan University’s Hedgcock Fieldhouse both his junior and senior seasons.
“We had deep and talented teams but fell short of our goal of reaching the state finals both years,” Mackey said.
He won the Ed Helakoski Award as the most valuable senior in the Porcupine Mountain Conference. Even though he was a 1,000-point scorer, he took pride in other aspects of the game.
“I played the forward position, oftentimes guarding the opposing team’s best inside player,” Mackey said. “I prided myself on being a hardworking and unselfish player. I really enjoyed passing the ball to teammates for their scoring opportunities.”
Mackey went on to play basketball at Gogebic. After graduating from Northern Michigan University, he eventually got a call about an opening for a part-time business instructor and women’s basketball coach at Ironwood’s college.
He was excited to take over the team heading into the 1988-89 season. Six years into his tenure, he led a balanced Samsons team to the program’s first national tournament. They won another Region 13 title three years later.
Another E-TC graduate, Deke Routheaux, retired as men’s coach after the 2005-06 season. Mackey didn’t make the switch, instead opting to coach his daughter Caitlin in her first season at Gogebic. The job opened up again a year later, and he debuted as men’s coach in for 2007-08. They men won Region 13 championships in both 2011 and 2013, just missing trips to the national tournament both years.
He said the goal was to win more games and Region titles, but his teams usually left it all on the court.
Mackey finished his tenure with the women with a record of 256-227 and a 277-263 record with the men. “It’s often said that teams tend to take on the identity of their coach,” Mackey said. “As I walk out the door, I’ll leave knowing my teams, like their coach, were known as fierce competitors.”
His signature saying is printed on the Lindquist Center court, “Coach Mackey Court,” — ”Once a Samson, Always a Samson.”
He wants the entire college to succeed, beyond just the basketball program. He took a lot of pride in giving local players a chance to play college basketball. He still supports them after they graduate.
Players came back yearly to play in their main fundraiser, the Spring Thaw Classic.
When GCC named the court after him, many of those he left an impact on filled the Lindquist Center gym on a random Tuesday game night in November.
Many appreciate the impact he had on their lives. He knows the importance of sports, whether it’s at the college level that he’s been at the last nearly 40 years, or at E-TC, where he got his start.
“Participation allows many to express themselves in ways that open doors to other life opportunities,” Mackey said. “High school athletics provide opportunities for youth to develop individual skills while learning life lessons at the same time. No matter the sport, learning to be a great teammate is challenging for most young people. Dedicating one’s time and efforts to improving oneself while also helping the team be better can be difficult. We all strive to be the best and win games, but are we willing to do the work to achieve the desired results? Everyone enjoys receiving the accolades, but many are unwilling to sacrifice the time and energy required to improve and develop individual skills, which enables this to happen.”
All three of wife Andrea (who was a big help to the GCC program as well) and his kids, Caitlin, Jesse and Adam, played high school basketball and then for Gogebic as well. Dennis said Adam was a similar player to him but a better scorer — he’s Ironwood’s all-time leader — who also wanted to get his teammates involved. They all teach at Ironwood now; Adam is the boys varsity basketball coach and Jesse the varsity girls coach.
The Mackeys continue to pass on many life lessons via high school sports.
“The thrill of victory and the agony of defeat not only applies to the games we play but to life in general,” Dennis said. “Success in high school is often measured with wins versus losses, but in the game of life the valuable lessons learned from the sports we play provide a platform for future growth. There are many folks employed in a variety of vocations who often credit their youthful days of playing sports as the impetus for their success later in life. The bonds created with teammates and opponents often last a lifetime. These bonds are immeasurable and help many advance in all facets of life.”

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.”
