Trenarys Trade Roles, Mendon Reigns On
October 8, 2015

Special for Second Half
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."

October 29, 2025
League championships have been all but decided, Districts are assigned and brackets drawn, and we’re only a few days from the start of this season’s MHSAA Girls Volleyball Tournament.
That means we’ll be coming back shortly, as our “Block Party” schedule moves up the next edition to Monday so we can preview some of the most intriguing District brackets across the state and all four divisions.
Until then, below are a few more regular-season observations as teams continued with their final tune-ups:
Week in Review
The countdown of last week’s five most intriguing results:
1. Rockford d. Farmington Hills Mercy (24-18, 23-25, 15-6) The East vs. West Challenge at Lowell was another opportunity for the Division 1 top-ranked Rams (40-1-1) to show their superiority among the state’s elite – which they did, not only defeating then-No. 2 Mercy (18-4-2) but also new No. 2 Bloomfield Hills and No. 7 Utica Eisenhower among others.
2. South Lyon East d. Farmington Hills Mercy (25-19, 18-25, 25-13) Outside of Rockford, there may be no team hotter than Division 1 No. 5 South Lyon East (37-7-1), which has won 11 straight and followed this with a sweep through the Lakes Valley Conference Tournament.
3. Bloomfield Hills Marian d. Detroit Country Day (25-16, 25-16) The Division 1 No. 4 Mustangs (43-5-0) have won 20 of their last 23 matches, and went 3-0 at the Country Day quad Monday including this sweep of the Division 2 top-ranked Yellowjackets (16-8-0).
4. Grand Rapids Forest Hills Northern d. Tecumseh (25-21, 25-21) The Division 1 No. 6 Huskies (33-8-1) handed just the second defeat this season to Division 2 No. 6 Tecumseh (51-2-0).
5. Plymouth Christian Academy d. Ubly (25-20, 25-21) A 5-0 run through the Mt. Morris Tournament by Division 3 No. 2 PCA (37-8-1) including this win over the Division 4 No. 3 Bearcats (25-10-4), plus sweeps of Charlevoix and much larger Holt, Essexville Garber and Cadillac.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
East Grand Rapids (29-10-0) The Pioneers are among honorable mentions in Division 1 again this week, and despite a pair of losses to Division 2 No. 3 Grand Rapids Christian over the last eight days bounced back to defeat No. 4 Grand Rapids Catholic Central and Division 4 No. 2 Fowler heading into these final few days of the regular season. EGR already has bested last year’s record of 26-16-5 and will enter its District next week as the second seed to Forest Hills Northern. Eight of the team’s losses have come against top-10 teams in Divisions 1 and 2.
Zeeland East (29-4-0) Although the Chix did lose out on a league title Monday falling in five sets to Division 2 No. 5 Holland Christian, that was the team’s first defeat since facing Holland Christian on Sept. 23 – and the only other losses this season came to Division 1 No. 10 Grand Haven. Zeeland East also is among honorable mentions this week and seeded second in a District behind another honorable mention in Byron Center. The Chix do have an early-season win over Holland Christian and have defeated Division 2 honorable mention Marshall and Division 3 No. 6 Kalamazoo Christian among others.
DIVISION 2
Detroit Country Day (16-8-0) The reigning Division 2 champion has been ranked No. 1 this season for all but two weeks, and moved back into the top spot this week after a four-set win over Bloomfield Hills on Oct. 21 – which avenged a loss from the season-opening quad Aug. 26. All eight losses have come against Division 1 opponents, with six to teams ranked or receiving honorable mention currently. Country Day is seeded first in its District, which empties into a Regional that could include No. 2 North Branch or No. 7 Imlay City.
Holland Christian (23-8-0) As noted above, the Maroons have clinched a share of a league championship, in the Ottawa-Kent Conference Black and with Spring Lake to finish the schedule. The closing run to secure the title came after a four-match losing streak that included three defeats to ranked Division 1 teams at the Jenison Invitational, and seven of the team’s losses total have come to ranked or honorable mention opponents. The Zeeland East win noted above also gave Holland Christian one more this season than last, and the Maroons will head into District play a top seed.
DIVISION 3
Byron (28-3-1) The Eagles have won nine straight matches including all four Saturday at the Marine City Cardinal Mooney Invitational, and they already have five more victories than last season – when Byron reached the Regional Finals. They’ve played several matches against Division 1 and 2 opponents this fall, with two of their defeats coming from teams in those divisions, and they also have notable victories over Alma and New Boston Huron among larger-enrollment foes. Byron also will be a top seed in its District.
Morley Stanwood (27-12-0) With eight wins over its last 10 matches, Morley Stanwood has joined the list of honorable mention teams in Division 3 the last two weeks. The schedule has included showdowns with several ranked opponents, with losses to No. 1 Roscommon, No. 2 Plymouth Christian Academy, No. 3 Kingsley and twice to No. 10 Beal City. That schedule has paid off as Morley Stanwood will enter its District as a top seed but with Central State Activities Association rival Kent City the second seed and after Kent City won two of three meetings this fall including in Saturday’s league tournament.
DIVISION 4
Mount Pleasant Sacred Heart (23-8-6) The 2022 Division 4 champion also made the Quarterfinals in 2023 and the Semifinals a year ago, and has prepped for another potential extended run facing a slate of larger schools and several that also are ranked. Sacred Heart is No. 4 in Division 4, and half of its losses this season are to Division 3 No. 10 Beal City, with the rest to Division 1 honorable mention Traverse City Central and three other Division 1 or two schools. Meanwhile, the Irish also have wins over Division 4 No. 2 Fowler and honorable mention Grand Rapids Sacred Heart.
Wakefield-Marenisco (19-7-0) The Cardinals opened this season with a 3-4 showing at the Copper Mountain Conference tournament, but have since avenged two of those losses and another early-season defeat in downing Ewen-Trout Creek last week. W-M has won eight straight matches since falling to No. 5 Crystal Falls Forest Park at the Trojans’ invitational on Sept. 20, and three losses this season have come against Lake Linden-Hubbell (23-5-0). The Cardinals are seeded second in their District to Forest Park and Thursday against Ironwood can equal their 20 victories of a year ago.
