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 Lyon's Wesner Turns Full Focus to School Sports, Big Finish to 11-Letter Career

SOUTH LYON — South Lyon senior Teagen Wesner isn’t hesitant to offer advice to younger athletes on the benefits of playing high school sports.
“It teaches you a lot, it brings you good friends,” Wesner said. “Being on the court and being on a team, it just brings you so much more knowledge you can’t learn in the classroom. I’ve learned so many things through sports, it’s something that’s irreplaceable to me.”
And younger athletes should certainly listen to Wesner, given she is quite an example of someone who has fully embraced all that high school sports have to offer.
When she graduates in a few months, Wesner will have 11 varsity letters, earned as three-sport athlete from the moment she arrived at South Lyon High School.
She has been on the varsity volleyball and ski teams since she was a freshman, and has been a member of South Lyon United’s lacrosse team since she was a sophomore (after playing on the JV lacrosse team as a freshman).
“It made me be a well-rounded athlete,” Wesner said of playing multiple sports. “I’ve gotten thrown into a whole bunch of different positions depending on what the coaches need. Having a background in multiple different sports really has helped my athleticism. I feel like I have matured a little more than others because I’ve been in highly competitive environments.”
Wesner said she has skied since she was 3 years old and played club volleyball since she was in elementary school, but made a decision during her junior year that reflected how much she loves playing high school sports.
Instead of playing club volleyball again after that high school volleyball season ended, Wesner decided to concentrate more on her high school teams.
“I just liked high school sports better,” she said. “Club was a lot of fun, but high school has all the people and everything.”
This past fall, Wesner was a captain of the volleyball team and an all-league performer in the Lakes Valley Conference.
This winter, Wesner is serving as captain of the South Lyon United ski team, as she hopes to build on a junior season where she was all-conference in both slalom and giant slalom.
In the spring, Wesner plans to once again play lacrosse and try and repeat what was an improbable success story last year.
Wesner, who said she stopped playing lacrosse in middle school before picking it back up again during her freshman year, took over as South Lyon United’s goalie in the fourth game of the season after the original starter was lost for the season with a torn ACL.
Wesner had played twice as goalie while in middle school, but was mainly a defender. However, desperate times called for desperate measures, so Wesner took over.
“Our goalie tore her ACL and we really didn’t have anyone else on the team, (to play the position),” Wesner said. “I just did whatever my coach needed. She knew with my background in other sports, I could pick it up quickly.”
Weeks later, Wesner and South Lyon United ended up celebrating its first MHSAA Finals championship with a 6-3 win over Hartland in the Division 1 title game.
“Taking a demanding role under high pressure, Teagan remained positive, composed and team-focused throughout the transition,” South Lyon United girls lacrosse coach Deanna Radcliffe said. “Her willingness to do whatever the team needed, combined with her resilience and steady presence, gave the team confidence during a critical stretch of the season.”
Recovering from losing its starting goalie early in the regular season to winning Division 1 was quite an improbable journey, but South Lyon did it with a stout defense and Wesner adapting so quickly her new position.
“I just kind of learned on the fly and let my instincts take over,” Wesner said. “During the season, I definitely got more training that made me way better. At the start, it was just like, 'Don’t let the ball hit you.'”
This spring, Wesner likely will return to her natural position as a defender with the starting goalie expected to be healed from her injury.
At the moment, Wesner doesn’t plan to play any of her three sports in college other than at an intramural level, which will make her cherish her high school years and all those varsity letters even more.
“I’m probably going to put them in a drawer,” she said. “But I think it’ll be cool to look back on. I’ll definitely glow on it for a couple of days. I think it’s a good accomplishment to something I’ve been working towards all four years of high school.”
