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."

Mercy Stands Tall at Net, Makes Big Blocks Pay Off in Championship Win

BATTLE CREEK – Farmington Hills Mercy looked to be on its way to a sweep Saturday in the Division 1 Volleyball Final at Kellogg Arena.
So when Bloomfield Hills erased a nine-point deficit in the third set, extending the match and delaying the Silly String celebration, the Marlins were on the wrong side of a massive momentum swing.
They were also incredibly calm.
“I feel like our message was not to worry,” Mercy senior Ella Andrews said. “We were down in the Semifinals two sets and came back and reverse swept them, so I feel like our message was just to stay calm. We can trust ourselves. We’ve been working for this all season, we just have to rely on each other and feel confident in ourselves to get back and score those points to win the set.”
Mercy got back to its game in the fourth set, and put itself back on top of the state with a 25-18, 25-20, 23-25, 25-20 victory against Bloomfield Hills.
The win gives the Marlins their third Finals title and second in three years. And, for the second time since 2023, they doused their coach Loretta Vogel with water and Silly String.
“I’m going in there to talk to everybody in the locker room, and I just get drenched,” Vogel said. “It’s definitely becoming a custom here.”
Mercy entered the fourth Final in program history with a simple, yet difficult gameplan: Slow Bloomfield Hills star Kayla Nwabueze. The Harvard-bound outside hitter did manage a match-high 24 kills, but the Marlins’ long, talented front line made it as difficult on her as possible.
“Our plan was to shut down Kayla,” said Vogel, who puts Nwabueze among the best hitters she’s seen in her 49 years coaching. “Put big blocks up, make them change to something else. That worked for us. I thought the girls really got up there and put four hands in front of her. There was one time we triple-blocked. So, I think changing something up like that, giving her a different view, had an impact on her. For any hitter, that would have an impact.”
Nwabueze got some backup from sophomore Allison Stakoe, who had 20 kills and played a massive role in the third set comeback.
But Nwabueze admitted it was tough to try and navigate the Mercy blockers.
“I would say it was really frustrating,” she said. “I knew they were going to come out and try to stop me, so I just had the mentality of don’t let that happen. I feel like I got into a rut a couple times. That’s what they tried to do, to stop the player that caused the most damage, and it was smart on their part. I really tried hard to try to get past that block. It was a really big block, though.”
McKenzie and Ella Andrews led the way on that block, with Ella finishing the match with two solo blocks and five assists, and McKenzie tallying six block assists. They had a ton of help, too. Kaelyn Easton had five block assists, Saniya Tucker had four, and both Cree Hollier and Kate Kalczynski had two.
Mercy’s attack was just as varied.
Kalczynski led the way with 16 kills, including the final one on match point, while Ella Andrews had 13, Hollier had 12 and McKenzie Andrews had seven.
That distribution was thanks to their freshman setter Easton, who had 43 assists in the Final and more than 100 over the final two matches.
“Definitely just seeing open spots where the blockers were,” Easton said. “I know in this game, the middles were open a lot, were scoring a lot, especially in the last set, and the coaches were just like, ‘Get them the ball. Just get them the ball and make them score.’ Also, the outsides, they opened up the middles a lot, so really, really appreciative to all of them. I could just not do it without the passes. The passes were really, really good this weekend.”
Maya Zarow led Mercy (42-5-3) with 24 digs, while Kalczynski had 12 and Easton 11.
Bloomfield Hills (43-8-1) setter Brynn Wilcox finished the day with 42 assists. Alyssa Moir led the defense with 20 digs, while Stakoe added 14, Nwabueze had 13 and Julia Colosimo had 10.
This weekend marked the first time the Black Hawks had advanced to the Semifinals.
“I’m just really proud of our team,” Wilcox said. “Even though we may have faced some ups and downs throughout the season, we kind of leaned on each other. It’s probably one of the greatest – I’ve had the most fun of my life.”
