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."

O-G Overhaul Continues to Deliver as Bulldogs Clinch League Title Repeat

Barb Hellebuyck was honored to return to her alma mater and take on the challenge of rebuilding the Owendale-Gagetown volleyball program.
Having played for the legendary Judy Campbell, Hellebuyck knew what success at Owen-Gage looked like. With her granddaughter entering the program, she had an idea of the type of talent there was on hand to aid in the process.
She was not quite as aware of just how deep the rebuild would have to go, however.
“I remember, and I don’t know what team it was, they came to play a game at our gym and picked up the raggedy balls we had – the look on that girl’s face,” Hellebuyck said. “I went, ‘Oh heck no. We have got to do some upgrading here.’ These girls deserve to look good, to feel good, then that will help them play better when their confidence goes up. It started with new balls, then we got new carts, new uniforms, we have two new net systems now. Everything has been building for these girls, and they should have all that stuff.”
With its new equipment on hand, and its coach now in her fifth season, the Owen-Gage volleyball team is not only rebuilt but flourishing.
On Tuesday night, the Bulldogs clinched their second-straight Big Thumb Conference Red title, also their third in four years. Prior to winning the 2022 title, it had been 17 years since Owen-Gage had won a league championship.
That 2005 title was the last of 11 straight for a once-dominant program, constructed by Campbell as she built a 500-139-25 record over 20 seasons during the team’s infancy. From 1977 through 2008, Owen-Gage won 27 league titles, 21 District titles and five Regional titles. The school had nearly run out of room on the banner hanging in the gym.
Now, it finally has some numbers to justify getting a second one.
“It’s been very eventful – our team has really developed over the years,” said Owen-Gage senior Aubrey Hellebuyck, who joined the varsity team as an eighth grader in 2021. “We’ve really changed the program and turned it all around. We went from being last in the conference to being a championship contender. It’s really awesome to be a part of that.”
Aubrey Hellebuyck is one of three seniors on Owen-Gage’s eight-player roster this season, joined by Ayriona Maikrzek and McKenzie Baker.
They also happen to be the only three girls in the school’s four-student senior class. Owen-Gage is among the state’s smallest 30 schools in terms of MHSAA classification, with an enrollment of 41. The towns of Owendale and Gagetown have a combined population of less than 600 as of the 2020 census.
Because of its size, Owen-Gage can have eighth graders play varsity sports, as Hellebuyck did. They also have students as young as seventh grade playing on the JV team.
For some, that could be intimidating. But at Owen-Gage it’s been embraced.
“Having no experience, it was very hard,” Owen-Gage junior Jessica Bowers said. “We were going against teams that would have freshmen and sophomores, while I’m just a seventh grader who had never played before. But it made me develop faster because I had to lock in and focus when I’d be going up against people that were a lot bigger.”
A smaller school population also forces players to learn to become more well-rounded. Not only because of the small number of substitutes, but because there’s no guarantee the population will provide a player that fits a specific position.
“They are all phenomenal players in my mind, because we have a lot of them that play all the way around,” Barb Hellebuyck said. “They have to be good at the net, they have to be good in the back row. They’re really phenomenal players. They’re not always the tallest ones, but I have several players that do multiple things. We just have to.”
Again, it’s something Owen-Gage players have embraced.
“I’m a middle, and normally at other schools the middles never play all around,” Bowers said. “When I first started, all I focused on was hitting. Gradually I had to force myself to learn to dig a ball because no one could play back row for me. Eventually I got really good at it. On a bigger school team, I don’t think I would have to do that.”
With that buy-in, it’s no surprise that Owen-Gage has returned to its winning ways. This year’s team is 19-4-1 overall, having won 13 straight matches. It has not lost since Sept. 9.
The Bulldogs have two regular-season matches remaining before the District tournament, which begins Nov. 3. With a league title wrapped up, that’s the next goal, to end another 17-year drought and claim the school’s first District championship since 2008. In their way is Division 4 No. 2 Ubly.
“There’s a chance we could do that,” Aubrey Hellebuyck said. “It would be a huge upset, and it would be insane. We’re working toward that.”
That possible title would be made even more special by the fact it would be won in the Bulldogs’ home gym, as they are hosting. That’s another source of pride, just five years removed from side-eyed looks over the state of the program’s equipment.
“Barb puts a lot of work into that,” said Aubrey Hellebuyck, who added that she’ll go back to calling her “Grandma” after the season. “She’s a great coach, but she actually does a lot of fundraising just so our program has a lot of opportunity. We had one net, and it was horrible. Now we have two brand-new nets that are great. Our old ball cart, it was not a ball cart, I don’t even know what it was. But it’s not embarrassing to bring out our ball carts anymore for home games.”
