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."

Jenison Ace Enters Senior Season Fueled by Team's 2024 Breakout Success

JENISON – Karis Chatfield will remember last year’s Division 1 District Final against Hudsonville as one of the best days of her life thus far. 

West MichiganIt was a day that erased several years of heartbreaking losses for the Jenison volleyball team. 

“I will talk about that day forever because it was one of the best feelings I’ve ever had,” the senior standout said. “Some of the girls we played against were my best friends and they had beaten us the last two years, so to pull off that win in that atmosphere and to do that in front of that crowd and then to be able to play in the Regional Finals on our home court was just an awesome opportunity.”

Jenison swept rival Hudsonville 3-0 to claim its first District championship since 2013 and then defeated Mona Shores in the Regional Semifinals.

The season ended against Rockford in the Regional Finals, but that loss is fueling this year’s team.

“That's our goal again this year, but our goal is to get even further,” Chatfield said. “I think the loss to Rockford is going to light a fire under our butts. Not every girl plays at a super-high club level and hasn’t been in those situations to see those lights when the pressure is on you, so I think they learned a lot about what it takes mentally. I think that will help a lot this year.”

Chatfield, a returning all-state first-team selection who has committed to East Tennessee State, will be joined by several key returnees, including senior Charlee Cochran and juniors Ava Bush-Nelson, Rylee Paddock and McKenzie Thompson.

Wildcats coach Teran Peerboom-Vanderbroek said last year’s MHSAA Tournament run gave her team a taste of playing in pressure-packed moments against quality competition.

“Now that they’ve seen that and been there, they kind of got the feel for it and they know that they can do it,” she said. “Yes, the big stage was new to us, but we handled the pressure and we are ready to go this year. We beat Rockford twice last year, we beat Northville, so they’re excited for the opportunity to be on that platform again.

Chatfield and her teammates celebrate their District championship last season.“We want to win and go further than last year, and I definitely think we have the potential and the talent to do so.”

Chatfield, an outside hitter, has emerged as one of the top players in the state and was named a finalist for Detroit Free Press Preseason Player of the Year.

As a junior, the 5-foot-11 Chatfield registered 518 kills, 470 digs, 62 assists, 73 aces and 39 blocks. She is among the program’s top three leaders in kills, digs and aces.

“Skill-wise, she’s just so talented and it’s her dedication to practicing, to the sport,” Peerboom-Vanderbroek said. “She’s playing non-stop year-round, trying to get touches and trying to improve. She doesn't want to be mediocre, she wants to be great, and she has a very high expectation for herself.”

Chatfield is taking all of the preseason hype in stride.

“Volleyball is still a game and what I love to do, so I don’t feel a ton of external pressure,” she said. “I’m just having fun with it and setting these goals for myself. If I achieve them then that’s awesome, but if I don’t then it gives me something to work harder for in the future.”

Chatfield had already eclipsed 1,000 career digs, and Tuesday night against West Catholic she reached 1,500 career kills.

“I came into my senior year with a lot of goals,” Chatfield said. “Some of these goals I already achieved and I’m just adding layers onto them, but for me it’s more of a team sport than an individual sport so I really want to focus on what my team has done for me and things that have allowed me to get where I am.”

Chatfield’s competitiveness can be attributed to her family background.

“We’ve always been super competitive, and that competitive edge in me just always wants me to be the best and make my teammates better,” Chatfield said.

The Wildcats, who shared the Ottawa-Kent Conference Green title last year with Caledonia, have opened the season with eight wins over their first nine matches.

“They’ve been playing well, and we are just figuring out what we are going to do with our lineup and trying to solidify that before conference starts because we have a lot of options,” Peerboom-Vanderbroek said. “A lot of our players are just so versatile and they can play multiple positions. We are just trying to figure out what is the best fit for our team this year, and I think that speaks to our players that they can play so many positions so well.”
