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."

Block Party: 2025 Girls Volleyball Week 4 Report

A significant reason we've been able to begin reporting on the weekly progress of Michigan's volleyball teams this fall was the addition of Michigan Power Ratings as a contributor to the sport's MHSAA Tournament format for the 2024 season.
MPR is used to seed the top two teams in every District, and requires all to report their schedules and scores throughout the regular season. Those ratings take into account not only a team's success but also its strength of schedule, and MPR is constantly updating as matches finish and results are published to the MHSAA website.
Check out the Michigan Power Ratings (MPR) page for more details, but also note that rankings referred to below instead reflect the latest polls posted by the Michigan Interscholastic Volleyball Coaches Association (MIVCA).
Week in Review
The countdown of last week’s five most intriguing results:
1. Mount Pleasant Sacred Heart d. Fowler (25-19, 26-24, 11-25, 25-13) The Irish (11-3-3) were ranked No. 8 last week but have jumped two spots after defeating the formerly top-ranked Eagles (9-3-1).
2. Grand Rapids Forest Hills Northern d. Byron Center (25-16, 25-17) This Huskies win arguably sticks out most from a Makayla Kohn Memorial Tournament run that also included victories over Forest Hills Central, Traverse City St. Francis, Edwardsburg and host Caledonia, with the 5-0 day sending FHN to 16-5-0 overall.
3. Hudsonville d. Grand Rapids Christian (25-22, 26-28, 25-17, 20-25, 15-12) West Michigan is powerful as usual, and these are two of the best again with Hudsonville (9-2-0) an honorable mention in Division 1 last week and Grand Rapids Christian (7-4-0) No. 2 in Division 2.
4. Northville d. Bloomfield Hills (25-22, 25-20) Although Northville lost to White Lake Lakeland on Saturday, downing Division 1 No. 3 Bloomfield Hills and also Division 2 No. 3 North Branch at the Motor City Power Series showed what the Mustangs (4-2-0) can do.
5. Battle Creek Lakeview d. Plainwell (25-23, 26-24) Lakeview (14-3-4) finished 3-0-3 at its invitational, with sweeps of Portage Northern and Pontiac Notre Dame Prep its other wins.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Bloomfield Hills Marian (23-1-0) Although No. 2 Marian did absorb its first loss of the season last week in three sets against No. 3 Bloomfield Hills, it also has a win over Bloomfield Hills this season and its opponents have won 62 percent of their matches this fall – making the entirety of Marian’s work even more impressive. The Mustangs also have wins over No. 5 Utica Eisenhower and No. 10 Brighton with their first meeting with No. 4 Farmington Hills Mercy set for Wednesday.
Grand Haven (21-3-0) The No. 6 Buccaneers opened this season with a loss to Brighton and have fallen only twice more, to top-ranked Rockford and No. 8 Forest Hills Northern. They also have a win over Forest Hills Northern and this weekend went 6-0 at their Grand Haven Invitational, defeating honorable mention Zeeland East in the championship match after losing the first set. The Bucs also have victories over honorable mention South Lyon East, Grand Rapids Christian and Division 2 No. 6 Grand Rapids Catholic Central.
DIVISION 2
Imlay City (17-4-0) The No. 5-ranked Spartans are coming off a 3-1 Motor City Power Series weekend, with wins over Division 1 Saline and Lake Orion and Division 2 Goodrich and the loss in three sets to South Lyon East. Their only other losses were to Brighton, Utica Eisenhower and Division 3 top-ranked Monroe St. Mary Catholic Central, and they’ve also defeated Division 2 No. 7 Frankenmuth as they’ve powered up their schedule again this fall.
Tecumseh (19-1-0) A two-set loss to Division 3 No. 2 Roscommon is all that’s stood between the reigning Division 2 runner-up and perfection this season, with wins over honorable mention Parma Western and Division 3 No. 4 Kingsley among factors in Tecumseh’s No. 9 ranking this week. The Southeastern Conference power is coming off of a 6-0 run at the Mason invitational during which it didn’t lose a set.
DIVISION 3
Kingsley (21-4-0) After last season’s run to the Division 2 Regional Finals, Kingsley is ranked No. 4 in Division 3 and powering through its schedule with its only losses twice to Roscommon (see below), once to Tecumseh (see above) and to Flat Rock. The Stags finished 5-0 at their invitational over the weekend, highlighted by a two-set win over No. 9 McBain that included a 31-29 opener. Kingsley also has a win over Essexville Garber, which ended its season a year ago, an earlier three-set win over McBain and two-set victories over Division 3 honorable mention Manton and Division 4 No. 9 Onekama.
Roscommon (23-1-0) The Bucks have gone from losing their District opener in 2022 to reaching the Regional Finals the following season and Quarterfinals last fall, and they’re on the move again. Roscommon’s only loss this fall came in three sets to No. 7 Traverse City St. Francis on Sept. 4, and they have the wins over Kingsley noted above plus two more over McBain and Tecumseh. The Bucks won all five of their matches at Saturday’s Grayling Invitational comfortably.
DIVISION 4
Crystal Falls Forest Park (14-1-0) After reaching the Division 4 Semifinals in 2022 and 2023, Forest Park was stopped by Hancock in a Regional Final last season. The Trojans avenged that loss Saturday with a 25-17, 25-17 win over the Bulldogs in the championship match of The Rock Invitational at Gladstone. Only Division 3 No. 10 Saginaw Valley Lutheran has put up even 20 points against Forest Park this fall – once in the Trojans’ two-set win at the season opening Mount Pleasant Sacred Heart Invitational, and then one more time when Forest Park fell to Valley Lutheran in that tournament’s semifinals.
Suttons Bay (11-0-0) After finishing 17-13 a year ago, Suttons Bay has almost equaled that win total over this season’s first month. The Norsemen won the McBain Northern Michigan Christian Invitational to start this fall and most recently have four-set wins over Buckley and Frankfort, defeating the latter Monday after losing the first set. Onekama next week and Traverse City St. Francis next month will be among biggest tests as Suttons Bay continued to build on its fast start.
Can’t-Miss Contests
Be on the lookout for results of these matches and tournaments coming up:
Wednesday – Farmington Hills Mercy (5-1-1) at Bloomfield Hills Marian (23-1-0) – These rivals met three times last season, with Mercy sweeping all three matches.
Thursday – Calumet (4-3) at Hancock (12-2-2) – The Copper Kings swept both matches between these Western Peninsula Athletic Conference rivals last season.
Saturday – Cristi Curtis Memorial Invitation at Byron Center – The Division 1 honorable mention Bulldogs (14-3) will welcome a solid field that includes Division 2 honorable mention Edwardsburg (12-6), Fruitport (11-4-1), Mattawan (8-8) and Grand Rapids West Catholic.
Saturday – Battle by the Bay at Essexville Garber – The Dukes (12-6-2) will host Clare, Mount Pleasant Sacred Heart (11-3-3) and Beal City (14-2).
Monday – Flat Rock (16-4) at Monroe St. Mary Catholic Central (12-1-1) – The Rams haven’t gotten a lot of attention during their successful start, but could earn it with another impressive showing.
