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."

Chase Remains On Pace as Wroubel Ranks 2nd Among Nation's Winningest Active Coaches

PONTIAC — While the Pontiac Notre Dame Prep girls volleyball team pursues wins in Michigan this fall, parents, supporters and others around the program are also paying attention to what a program in Alabama is doing.
Why? It has everything to do with a prominent coaching record on the national level.
At the moment, it’s a nice neck-and-neck race to see who will finish this season as the active coach with the most wins nationally, Betty Wroubel of Notre Dame Prep or Ann Schilling of Bayside Academy in Daphne, Ala.
Going into the season, Schilling had 1,796 career wins, three more than Wroubel. As of Wednesday, Schilling had added 16 wins to her total to make it 1,812, while Wroubel added 14 for a grand total of 1,807.
The two are also third and fourth, respectively, on the overall all-time wins list nationally. Two coaches who are retired, Jodi Manore of Temperance Bedford (2,231) and Jack Magelssen of Portage Northern (1,832), top the list.
Schilling and Wroubel are fast approaching Magelssen, but if there is one person who isn’t too occupied with it all, it’s Wroubel.
Sure, she has a good laugh or smile when parents or other school officials have casually come up to her over the past few weeks to mention the situation. But as has been the case throughout her legendary career, there is a greater purpose for her.
“It’s the kids’ winning,” Wroubel said. “I get to facilitate a little bit. But it’s really about the kids, and I’ve been blessed with some really good kids here over the years and some coaches who have coached with me.”
Notre Dame Prep senior Nicole McDowell said trying to win so Wroubel can keep up with Schilling hasn’t really been talked about much among players this season. But that doesn’t mean the chase can’t provide a little more incentive the rest of the fall.
“That will help motivate us more,” McDowell said.
The head coach of Notre Dame Prep since 1994, Wroubel remains an institution for not only her school, but the volleyball coaching community statewide.
Wroubel has guided Notre Dame Prep to four Finals titles in Class B/Division 2, with the latest in 2021. When Notre Dame Prep won the Class B championship in 2007 (fall season), the Fighting Irish not only captured the school’s first volleyball title but became the first program in Oakland County history to win at the Finals.
“I just love being around the kids, and they provide the energy and keep you going,” said Wroubel, who is also the athletic director and varsity softball coach at Notre Dame Prep.
Even as eras and the sport have changed drastically, players have enjoyed playing for Wroubel as much as she’s enjoyed coaching them.
“She really is competitive and she’s hard on us, but she wants to win and all of her intentions are good,” said McDowell, who has committed to play collegiately for Rider University (N.J.) and is a returning all-state player. “Outside of volleyball, she is the most generous person I know.”
Time will tell if Notre Dame Prep (14-12-2) can continue to pile up wins this season for itself and Wroubel.
While the coaching wins angle could be a fun storyline for the program and its supporters to follow, it certainly won’t sway Wroubel from her ultimate objective to make her players better volleyball players and women.
“I just love my job,” she said. “I think this is where God has placed me. There’s a place where we’re all supposed to be, and this is part of my mission. This is where I’m supposed to be. God has blessed me with great support and great athletes, and I just love it here.”
