Trenarys Trade Roles, Mendon Reigns On

Volleyball found Bill Trenary early on. Actually, countless volleyballs did.
“I was getting hit in the head with volleyballs before I could walk,” the Mendon High School varsity coach, now in his second year at the helm, said. “There’s a very good story about me getting knocked out of a walker in this very gym. I started managing when I was in second grade. Ever since then I’ve been in the gym playing volleyball.”
His mother, Michigan High School Volleyball Coaches Association 2014 Hall of Fame inductee Kathy Trenary, spent more than three decades guiding prep squads, most notably a 19-year run at Mendon that netted 721 victories, 10 conference championships, 15 district titles, six regional crowns, trips to six MHSAA Semifinals and championship victories in 1998, 1999 and 2001.
Growing up around the game undoubtedly sparked Bill Trenary’s interest in the sport. Like most boys, however, he was just as engrossed in other athletic and leisurely pursuits. He enjoyed the outdoors, beating his mother on the squash court and obsessively studying opening chess moves — a competitive fire serving as the common thread.
One unique experience in particular was likely what set Bill Trenary up for a successful career in volleyball.
His parents put a premium on experiencing other cultures. His father, Robert Trenary, was a Fulbright scholar at the University of Botswana when Bill was in the eighth grade. That enabled the Trenary family to live abroad for a year. Bill Trenary ended up setting for his school’s varsity team, which played outdoors under the African sun.
Bill and younger brother Matt went on to play intramural volleyball at the University of Michigan.
“They tried to win the championship but could never do it because a lot of kids on the team just wanted to play,” Kathy Trenary said. “I’d go to Ann Arbor and watch them play. That was great.”
It was about that time when Kathy Trenary took over as head coach at Vicksburg. It was an opportunity for Bill Trenary to fire some high-velocity shots inside high school gyms like those he remembered zipping at him as a toddler.
“I was in my 50s at the time and I said, ‘I really need a hitting boy,” she recalled. “I said, ‘would you like to come and be a hitting boy?’ He really identified with how much he liked (volleyball). He played it all growing up, but he maybe never realized how much he liked it until he started to coach it.
“He just found it fascinating; he has always been a gamer.”
In the years since then, Bill Trenary learned from the best, leading to his takeover of the Mendon program in 2014. Kathy Trenary stayed on as his assistant coach and the continuity was evident with the Hornets’ run to the Class D semifinals in 2014, which ended in a 3-0 loss to Battle Creek St. Philip. The arrangement has been seamless for the Hornets, who are currently ranked No. 6 in the latest MIVCA Class D poll.
“When we decided to switch, part of the reason was her being kind to me, I guess,” Bill Trenary said. “She saw me getting better. It was time for me to kind of step into that role. I think I’m a little better game coach because I’m younger and I can push through long Saturday tournaments and make the quick decisions on the court.
“She is absolutely one of the best coaches I’ve ever seen — attention to detail and running practices. She’ll run most of the drills because, heck, she invented most of the drills. Not utilizing her in that role would just be stupid. Me taking that away from her would just cost us points. There’s no reason not to be doing that when we have someone of that caliber.”
A fan of Tom Tango’s book “Playing the Percentages in Baseball,” Bill Trenary strongly believes in analytics and that some statistical aspects of volleyball are often overlooked and undervalued.
As are role players, which there are more of this year than freak athletes. That’s often the case at a small school such as Mendon, where fundamentals help offset height disadvantages.
This year Mendon has a “huge arm” in junior hitter Megann Leighton, exceptional leadership from seniors Brandy DeLeeuw and Emma Eberstein, lockdown play from junior libero Kaley Smith and reliable and consistent setting from junior Cassie Plummer.
“That’s how other teams see us win, but the way we win is when Nancy Steinacker can come and serve a string in our weak rotation,” Bill Trenary pointed out.
The points are in the details.
“We don’t have the best athletes every year, but we have a deep knowledge of the game, which is fun,” he said. “I’ve just tried to build on that. I know we’re using more math, more stats, more film than we have. That’s just a next generation sort of thing, but we’re not trying to reinvent the wheel."

Kingsley Scores Final Point of 2025 Season to Clinch Program's 1st Finals Title

BATTLE CREEK – For a set and a half Saturday, it was clear Kalamazoo Christian was the team with a championship experience edge in the Division 3 Volleyball Final against Kingsley.
The Comets were playing at Kellogg Arena for the fourth straight year, having won a title in 2023, finished runner-up in 2022 and reached the Semifinals as well in 2024.
But apparently that set and a half was all the time Kingsley needed to become comfortable in the moment, as the Stags rallied for a 22-25, 26-24, 25-15, 25-12 victory, claiming the program’s first Finals title.
“We got hammered the first game, just didn’t play well,” Kingsley coach Dave Hall said. “Just error after error, tight, and just out of nowhere they find it in them. In the second set we were down again, set point, and somehow they find a way to score a point and tie it. We’ve been in 25 of those this year, and have probably won 23 of them. They just don’t get rattled. I’m chewing my fingernails off and can’t look half the time, and they just play volleyball. It’s amazing.”
Hall’s illustrious career has spanned nearly three decades at Kingsley, as he’s won 1,230 matches in his 27 years with the program.
It was the second time he had taken a team to the final day of the season, with the previous for the Class C Final in 2004.
“It’s surreal,” he said. “I just told somebody that it’s probably going to be tomorrow before I realize what just happened. We’re just enjoying the win right now. … My daughter was just telling me she was 7 years old last time we were here. She’s 28 now, married. It’s awesome. I don’t even know if I have words right now to describe the feeling.
“Honestly, these kids have worked so hard. They got knocked out in the Regional Final in four sets (a year ago), and their goal was to come back and go further. Our motto has been one more day, one more day, just try to get to the end of the season. I said, ‘We’re going to play the last point of the volleyball season in the state of Michigan today, and it’s going to be match point and we’re going to win this thing.’ Thank goodness it worked out that way.”
It didn’t look that way early, as Kalamazoo Christian led from 4-3 on in the first set to take early control of the match. It then weathered a fast Kingsley start to the second before going up 24-22 with a chance to take complete command.
“I think we were playing really loose,” Comets coach Carlie Southland said. “Having a lot of fun and playing really disciplined in our passing, blocking and serving.”
Kingsley (57-4-1) would win the next four points, however, and never let go of the momentum, as Kalamazoo Christian (30-12-3) would never have another lead in the match.
“I think we were just kind of nervous at the start,” Kingsley senior setter Sarah Wooer said. “Then in the second set we realized that we were really in it, we just had to play hard. Once we realized that we were doing well and we could win, we just kept playing hard and we were able to pull it off.”
The lone glimmer of hope for Kalamazoo Christian came late in the third set, when it cut a 15-7 Kingsley lead down to 16-11. But a wild rally that included diving saves from Wooer, Isabelle Seitz and Aizlyn McKinley ended with a Jenna Middleton kill, and Kingsley rolled from there.
The play was a great representation of how the Stags played throughout much of the match.
“I think we all just read the hitters really well,” Wooer said. “We knew they had really good hitters, and we were able to adjust our block really well. Our blockers played a big part in it. Our defense played well, and we were able to just keep the ball off the floor, that’s all we try to do.”
Seitz led Kingsley with 28 digs, while Aizlyn McKinley had 22, Middleton had 15 and Ariyah McKinley had 14.
Wooer finished with 48 assists on the day, with Middleton coming in at 19 kills, Aizlyn McKinley at 15 and Delaney Case at 12.
Elliana VanDusen led the Comets with 18 kills, while Eliana Keller had 13. Lily Manion finished with 28 digs for Kalamazoo Christian, Ellory Zuiderveen had 11, and Reagan Zuiderveen had 36 assists.
