Fresh from Cancer Fight, Disbrow Returns to Coaching Ready to Continue 'Winning the Day'

Nikki Disbrow grabbed her keys and started to get into the family vehicle to pick up her son from a summer 7-on-7 practice. Her husband, Sand Creek football coach Sid Disbrow, told her he wanted to come, too.
“What are you doing?” she asked. “You can barely walk.”
Sid, who had just returned home from surgery to have a tumor removed while battling colorectal cancer for the second time in three years, wasn’t having it. He got in the vehicle.
When Nikki arrived at the field, Sid opened the door.
“Where are you going?” she asked.
Sid, unrelenting, got out of the car and began making his way to the field.
“She was kind of my walker,” he said. “I couldn’t walk on my own, but I needed to address the kids. I needed to be out there. I needed to show them that it’s about winning the day, because you never know what might happen.”
Disbrow, 49, has been coach for just about 30 years. It’s part of who he is in the Sand Creek school district and community. He’s been an assistant football coach, youth baseball and softball coach, varsity boys and middle school basketball coach. He’s detailed, organized, loves the competition and thrives on being around kids.
Last year around the eighth or ninth week of the football season, he began noticing the symptoms of the cancer he had chemotherapy and radiation to treat a couple years prior. He finished the season, knowing middle school basketball was getting ready to start.
Within a week of finding out the cancer had indeed returned, he was able to get everything scheduled and begin chemotherapy. He was getting treated at Flower Hospital in Sylvania, Ohio, about 45 minutes from Sand Creek.
“They would give me the last appointment of the day so I could get there after school,” he said. “They were great to work with.”
It wasn’t easy trying to maintain a rigorous coaching schedule while fighting cancer.
“There are no rules in cancer. You don’t get to do as you wish. Chemotherapy is real,” Disbrow said.
He wasn’t deterred. He coached the entire middle school basketball season – which ended around Christmas. Some days, he was exhausted. Still, quitting wasn’t an option.
“I wanted to be out there for my son and all of the other kids that I’ve been coaching all the way through,” he said. “That was important to me. That was my driving force.”
Not long after basketball season ended, he began eight weeks of radiation. It ended just in time for him to coach his son’s baseball team.
After that season ended, something still wasn’t right. Doctors found a tumor, although they weren’t sure if it was shrinking or growing. They gave him an option – surgery to remove it or wait a few months, get tested again. At that point, if it returned, it meant starting chemotherapy and radiation all over again. He checked the calendar.
“I thought about football season,” he said. “My son is on JV this year. That’s not something I want to miss.”
He went in for surgery and had the tumor successfully removed. Doctors found out later it was indeed cancerous and growing.
“I made the right decision,” he said.
He was recovering from that round of surgery when he made it onto the football field to talk to the Aggies players. The football field is more than a place for Disbrow to forget all about cancer and focus on the lives of the young men on the field. It’s a place him and Nikki, a former varsity volleyball coach at Sand Creek herself, got married.
“It’s probably the first time there was a wedding on the football field, and probably the last time,” he said.
On Aug. 3 – one week before two-a-days started for Sand Creek – he found out the cancer was in remission. He was back with the team when practice began.
“I brought my lawn chair with me,” he said. “There were some days where I just didn’t have the strength.”
Through it all, he’s endured, never wavering.
“The credit goes to God,” he said. “I don’t see how people go through something like this without their faith. I owe it all to Him. He’s given me this chance to continue to teach and coach. I don’t take that lightly.”
Sand Creek varsity football coach Derek Hewitt said seeing Disbrow come back to practice after all he went through was inspiring. Disbrow coaches special teams, the quarterbacks and helps Hewitt with the offense. On most Fridays he’s in the coach’s box.
“It’s great to have him back out there,” Hewitt said. “He’s not the scout team quarterback anymore, but he’s there, every day. It’s great for me to have him by my side.”
One thing Disbrow is not planning to do is stop coaching. In fact, he’s going to be even busier. He was recently named the school’s junior varsity boys basketball head coach.
“Coaching really kept me going through all of this,” he said. “The kids have been great through it all.”
The father of four is from Morenci, the neighboring town to the south and heated rival of Sand Creek, which he admits caused some angst when he moved from coaching football at his alma mater to Sand Creek.
He was part of the 1995 Morenci football team that played for a Class C championship in the Pontiac Silverdome, graduating in 1996. He was a sophomore at Adrian College when a Morenci coach asked him to join that coaching staff. A couple years later he began coaching at Sand Creek.
Now, he, his wife and four kids are engrained in the Aggies community.
“I wasn’t one of those people who got into teaching because I wanted to coach,” he said. “I wanted to be a teacher, to be around young people and help them. Coaching was something I loved once I started doing it. It’s who we are now as a family. It’s part of our lives.”

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.”
