Trenarys Trade Roles, Mendon Reigns On
October 8, 2015
By Wes Morgan
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."

November 10, 2025
After just a week, our list of MHSAA Finals hopefuls has whittled down to 128 who hoisted District title trophies – and they will have an opportunity to raise another Mitten in just a few days as they continue their march to Battle Creek.
Up next are Regional Semifinals on Tuesday, and all Regional Finals on Thursday. Links to interactive brackets for all four divisions plus information on purchasing tickets is available on the Girls Volleyball page, and a list version of this week’s slate is posted on the Scores page – with green TV icons linked to broadcasts on the NFHS Network.
See below for a look at District Finals that were among the biggest headliners, and glances at three Regionals in each division that should generate the most buzz. Records, results and schedules below are those posted for teams on MHSAA.com, and rankings reflect polls posted by the Michigan Interscholastic Volleyball Coaches Association.
Week in Review
The countdown of last week’s five most intriguing results:
1. Bloomfield Hills d. Bloomfield Hills Marian (18-25, 26-24, 25-20, 25-21) There’s no understating the significance of this win for No. 2-ranked Bloomfield Hills (39-6-1), as Marian (44-6-0) had made at least the Semifinals four of the last five seasons and won three-straight Division 1 titles from 2020-22.
2. South Lyon d. South Lyon East (27-25, 17-25, 18-25, 25-23, 15-6) The honorable mention Lions (35-10-0) hung on through the end of what could have been a match-clinching fourth set for No. 5 East (38-8-1), then dominated the fifth to avenge two regular-season losses with a Division 1 District title victory.
3. Romeo d. Utica Eisenhower (19-25, 18-25, 25-21, 25-18, 15-9) Unranked Romeo (27-10-1) claimed a Division 1 District championship by avenging a pair of regular-season losses to the Macomb Area Conference Red rival Eagles (33-5-3), who entered the postseason ranked No. 7 and won the first two sets of this match.
4. Parma Western d. Marshall (25-18, 25-21, 30-28) These Interstate 8 Athletic Conference opponents met for the third time, unranked Western (40-9-3) getting the win in this Division 2 District Final after No. 9 Marshall (32-12-5) won the first meeting and they played to a draw at the league tournament.
5. Grand Rapids Christian d. Grand Rapids South Christian (15-25, 25-20, 25-15, 25-22) The No. 3-ranked Eagles (24-8-0) locked up a Division 2 District championship, adding to a Sept. 2 win over the No. 8 Sailors (24-9-0).

Regionals at a Glance
These could be among our most competitive brackets. Host sites are in bold, and top two seeds at each are noted.
DIVISION 1
Hartland
South Lyon (35-10-0) vs. Brighton (32-7-2)
Orchard Lake St. Mary’s (28-6-3) vs. Farmington Hills Mercy (21-4-2)
Mercy has been considered one of the statewide favorites all season and entered the playoffs ranked No. 3. The Marlins have regular-season wins over South Lyon and Brighton but will see honorable mention St. Mary’s for the first time this fall. The Eaglets have won 21 straight matches and like Mercy are Catholic High School League division champions. Like St. Mary’s and South Lyon – the latter coming off its big win over No. 5 South Lyon East noted above – Brighton entered the postseason an honorable mention in Division 1 as well and has won 12 of its last 14 matches.
Hudsonville
Grand Rapids Forest Hills Northern (39-8-1) vs. Grand Haven (36-10-0)
Hudsonville (31-8-1) vs. Rockford (43-1-1)
All four entered the postseason ranked – Rockford at No. 1, Forest Hills Northern No. 6, Hudsonville at No. 9 and Grand Haven No. 10. The Rams have defeated Hudsonville three times, although the Eagles forced a fourth set in both league matches, and Rockford swept Grand Haven in their two Ottawa-Kent Conference Red meetings. Rockford and Forest Hills Northern last met in a Regional Semifinal last season, when the Rams won in four sets. The Huskies may get the chance to avenge but can’t look past Grand Haven; they’ve defeated Grand Haven twice this season but also lost in three sets when the teams met in early September.
Portage Northern
Mattawan (22-18-0) vs. Byron Center (34-5-2)
Caledonia (24-18-0) vs. Battle Creek Lakeview (38-8-7)
Byron Center entered the postseason as an honorable mention in the final coaches poll and also won its District a year ago before falling to Lakeview in a Regional Semifinal. The Bulldogs have a win over Mattawan and a pair over Caledonia this season but have not faced Lakeview this fall. The Spartans have a five-set win over Mattawan but will be seeing Caledonia for the first time this season as well. Lakeview did go on last season to reach the Division 1 Quarterfinals and avenged its only loss over the last month by defeating Portage Central in their District Final last week.
DIVISION 2
Charlotte
Parma Western (40-9-3) vs. Niles (16-16-0)
Battle Creek Harper Creek (30-21-1) vs. Tecumseh (53-2-0)
Tecumseh is ranked No. 6 and the presumed favorite this week after also finishing Division 2 runner-up a year ago, although Harper Creek also reached the Semifinals last season and should provide a challenge. Tecumseh has defeated Western twice and Harper Creek once this fall and not seen Niles to this point. But Western and Niles both are coming off what would be considered upsets last week, Western defeating No. 9 Marshall (see above) and Niles clinching its District title against honorable mention Edwardsburg after falling to the Eddies just two weeks before.
Grand Rapids South Christian
Grand Rapids Christian (24-8-0) vs. Holland Christian (26-8-0)
Grand Rapids Catholic Central (34-12-1) vs. Lake Odessa Lakewood (22-22-0)
As noted above, Grand Rapids Christian is ranked No. 3 and is seeking its first Division 2 championship since winning three straight from 2018-20. The Eagles own one win this fall over all of the other three teams competing at South Christian this week, but this Regional is loaded with Grand Rapids Catholic Central ranked No. 4 and Holland Christian ranked No. 5. If Holland Christian were to get past Grand Rapids Christian and see the Cougars, it would be a first meeting this fall between those two. Lakewood and Grand Rapids Catholic Central also are meeting for the first time.
Yale
Marysville (31-13-1) vs. Detroit Country Day (19-8-0)
Pontiac Notre Dame Prep (31-14-2) vs. North Branch (40-8-0)
This Regional is anchored by the reigning Division 2 champion Yellowjackets and top-ranked North Branch, which overtook now-No. 2 Country Day in the final coaches poll. They have not faced each other this season, but Country Day won their Quarterfinal match a year ago in five sets. There is plenty of intrigue in this bracket because of the two unranked teams as well. Marysville and Notre Dame Prep also are among the most successful programs in MHSAA history, and the Fighting Irish won the Division 2 title just four years ago. Both Regional Semifinals are first-time meetings this season. Marysville did win its lone matchup this fall with NDP, at the latter’s invitational in September.
DIVISION 3
Centreville
Kalamazoo Christian (26-12-3) vs. Bangor (28-5-2)
Constantine (27-10-3) vs. Bronson (28-17-6)
Kalamazoo Christian defeated Bangor and Bronson at last year’s Regional on the way to reaching the Division 3 Semifinals in Battle Creek. The No. 8-ranked Comets haven’t faced either this season but do have a win over Constantine. Bronson, an honorable mention heading into the postseason, hasn’t faced any of this week’s possible opponents but has taken all but one of its losses this season from Division 1 and 2 teams. Bangor is 15-2-2 since the start of October, and Constantine has won 11 of its last 13 matches – although Bangor dealt the most recent defeat.
Clinton
Hanover-Horton (41-1-1) vs. Jackson Lumen Christi (16-16-1)
Grass Lake (25-13-4) vs. Monroe St. Mary Catholic Central (23-4-1)
Reigning champion Monroe St. Mary prepped for this run with another schedule of nearly all Division 1 and Division 2 opponents. In addition to facing tough competition, the added significance of that for this week is the Kestrels and Hanover-Horton haven’t met since SMCC won their Quarterfinal a year ago. The Comets opened this season going 2-1-1 at the Chelsea Invitational – falling to Parma Western and tying Milford – and have won every match thereafter. They entered the playoffs ranked No. 4, with St. Mary at No. 5. Grass Lake has won 11 of its last 12 matches, the lone defeat to Hanover-Horton in the Cascades Conference Tournament. Lumen Christi has won seven of its last eight, the defeat coming against Grass Lake.
Houghton Lake
Roscommon (45-2-0) vs. Kingsley (52-4-1)
Beal City (34-9-1) vs. Breckenridge (36-6-3)
This Regional arguably packs as much punch as any in any division. Top-ranked Roscommon has lost only to No. 7 Traverse City St. Francis and Division 1 Caledonia, and has two wins over No. 3 Kingsley and defeated No. 10 Beal City in their lone meeting two weeks ago. The Bucks have lost only eight sets all season. Kingsley’s defeats were only to Roscommon and Division 2 Flat Rock and Tecumseh, and the Stags are on a two-month winning streak with only one tie mixed in. Kingsley has defeated Beal City three times, but all of the Aggies’ losses were to either ranked teams or Division 2 opponents. Breckenridge is unranked but 12-2 since the start of October and avenged its most recent loss by defeating St. Louis in their District Final.
DIVISION 4
Carson City-Crystal
Fowler (31-8-2) vs. Mason County Eastern (19-12-1)
Grand Rapids Sacred Heart (29-2-0) vs. Mount Pleasant Sacred Heart (25-8-6)
Fowler and Mount Pleasant Sacred Heart have bounced around the top 10 in Division 4 all season, settling in at Nos. 2 and 5, respectively, heading into District play. Sacred Heart actually won their lone meeting, in four sets Sept. 11. Fowler hasn’t faced Mason County Eastern this season, and the Cardinals are on a nice 8-2-1 run over the last month after a couple of rough patches earlier this fall. Mount Pleasant Sacred Heart defeated Grand Rapids Sacred Heart in four sets on Sept. 25, but Grand Rapids Sacred Heart’s only other loss was to Division 3 Fennville.
L’Anse
Crystal Falls Forest Park (39-1-0) vs. Hancock (26-4-2)
Norway (18-8-2) vs. Ishpeming (22-5-2)
This Forest Park/Hancock matchup has been one of the Upper Peninsula’s most anticipated all season after Hancock won last year’s Regional Final meeting and ended a two-year string of Trojans trips to the Semifinals. Hancock advanced instead, ending last fall at Kellogg Arena, but Forest Park avenged in their only match this season Sept. 13. The Trojans’ only loss this fall came during the first tournament of the season to Division 3 No. 6 Saginaw Valley Lutheran, and Hancock’s only other defeats came to Division 2 Kingsford and Negaunee and Division 3 Calumet. Norway is on a 15-3-1 run since mid-September and will take on an Ishpeming team that hasn’t lost in nearly a month – most recently falling to Hancock on Oct. 16.
Mendon
Mendon (34-6-1) vs. Martin (16-11-0)
St. Joseph Michigan Lutheran (28-7-3) vs. Battle Creek St. Philip (24-14-5)
Mendon is seeking its first Regional title since its most recent Division 4 championship season of 2019, and the top-ranked Hornets started a 14-3 run on Sept. 30 with a four-set win over No. 8 St. Philip. If they meet again, it will mean the Tigers ended Michigan Lutheran’s 10-match winning streak, during which the Titans have lost only one set. St. Phil last week won its District for the 26th-straight season and is seeking its first Regional title since its Division 4 title-winning season of 2021. Martin has won four straight District titles and nine of its last 11 matches this fall, with both losses during that run to teams still alive.
