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."

South Haven Celebrates Program Pioneers to Begin 50th Season, Aspires to Add to Tradition

SOUTH HAVEN — When the call went out for volleyball players, a whopping 115 students showed up at South Haven High School.
That was 50 years ago, and the daunting task of whittling down those numbers fell to coach Dene Hadden.
From that group of hopefuls, he kept 13 on varsity and 13 on junior varsity.
The biggest problem was that neither the girls nor the coach had ever been involved in the varsity sport.
That sure has changed.
Fifty years ago, when the MHSAA debuted girls volleyball as a varsity sport, 462 schools fielded teams, with 12,012 athletes. Last season, 16,679 players took the court for MHSAA high schools, and this season 697 teams are slated to play.
Those first years were tough, Hadden said.
"We tried to use some athletic skills, jump height, jump distance, some other tests that I read about and heard about,” he said.
Things got easier for Hadden the second year after he attended a volleyball camp in Chicago.
“I spent seven days and nights of intensive volleyball training and learned so much about the game from key ‘grandfathers,’ you’d have to say now, about volleyball and came back much more confident in what I knew, how to teach skills and what skills to look for. It made a huge difference.”
That huge difference made an impact on the South Haven program. In 1977, the Rams made it to the MHSAA Lower Peninsula Class B championship match and, in 1985, won the title. They also reached the Finals in 1980 and 1991.
Fourth-year Rams coach Wendy Spencer said today’s players do not realize how much they owe to those pioneers.
“I think so many of these girls take for granted all the battles that women had to fight for to just be an athlete,” she said. “Isn’t that such a blessing that this next generation doesn’t have to realize the struggle?
“We don’t take for granted how special it is. I think for (current athletes) to see on a board their (photo) next to someone who’s 50 years older than them can put it into perspective sometimes.”
The current athletes also got a taste of those trailblazing players two weeks ago during an alumni game celebrating 50 years of MHSAA volleyball.
Diane (Sherman) Skuza was one of the alumni. She joined the volleyball team her junior year in 1977.
“I was playing basketball and softball,” she said. “I tried out, had never played volleyball before. Dene saw something in me as an athlete.
“One of my strong points was my serving. He would often bring me in just to serve. My senior year I actually played quite a bit and was all-conference.”
The Rams won the Wolverine Conference her final two years (1977, 1978), finishing both seasons with identical 26-1 records.
At the alumni game, Skusa, who at 64 was the oldest player there, joined the other women in competing against current varsity players.
“When I played in the alumni game, they said, ‘OK, we’re gonna do whatever,’ and I didn’t know what they were talking about,” she laughed. “They said do you want to be a middle hitter or an outside hitter.
“We really didn’t do that. We had our positions. If you were on the left side, you hit from the left side. It’s a lot more involved now. But we had some really strong players, and Dene was a great coach.”
The alumni actually won the game, but they had a few ringers, according to Hadden.
“You have to remember the alumni had Hayley Kreiger, an All-American at Davenport a couple years ago playing that night,” he said. “We had some all-conference players, so there was some talent on the alumni side of the net.”
The alumni team also included former players from the 1985 championship team.
Hadden said that when organizers started planning the 50th anniversary celebration, “We wanted to recognize the 318 varsity letter winners who have contributed to the sport at South Haven.”
Rams return experience
For this year’s team, Spencer will rely on three returning seniors, including four-year varsity player Charlotte Knox, who already owns three school records.
She is first in career digs (742) and aces (28). She also has the single-season record in kills (365 set last year).
Her single-season achievements also include ranking fifth with most blocks (62 in 2022), second in most digs (298 in 2023) and tied for fourth with most aces (98 in 2023).
She is third in career blocks with 126 heading into this season.
In her second year as captain, Knox is “a kid who shows up for her teammates before she shows up for herself,” Spencer said. “She can keep that high level of expectations without coming down on people.
“Charlotte has consistently had the best stats in our region in kills, digs and aces. As a junior, she is already in the top five of all of South Haven history for season and for career.
Other seniors on the team are Charlotte Grzybowski, Areanna Wabanimkee-Gluck, Nevaeh Cooper and Kaitlin Moore. Juniors are Ly’nique Cunningham and Trinity Sistrunk, while sophomores are Kiersten Chalupa, Julia Wiley and Piper Allen.
Spencer noted that most players today hone their skills on travel teams outside the school season.
“Club sports have taken a huge role in athlete’s development, but I think there’s something missing if kids don’t want to play high school athletics,” she said. “School sports are important; club sports are important if you have bigger goals.
“These (school teammates) are the people you will remember, the ones you will show up at 50-year reunions with, not your club team. We’re trying to keep that going, and Dene’s the reason for that.”
Hadden, who coached the Rams for 19 seasons, still keeps active.
“He announces all our home games, he still shows up at all our tryouts,” Spencer said. “He’s just someone who loves our district and loves volleyball so much.
“He really keeps our traditions alive. He’s the only coach who won a state championship and runner-up twice. The question is, how do we learn from that?”
The reigning Southwestern Athletic Conference champ started the season repeating as champ at the Coloma Tournament last Saturday with Knox recording 74 kills to reach 1,000 for her career.
The Rams continue Wednesday against Constantine with one goal in mind: “The team works every year at Battle Creek’s Kellogg Arena (during the MHSAA Tournament),” Spencer said. “This year we’d like to be playing there, not on the sidelines.”
