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 1, 2025
Just a few weeks ago, we got this inaugural "Block Party" started. And this week, we've already surpassed the midpoint of the 2025 girls volleyball regular season.
District tournament play begins is just a little more than four weeks, on Monday, Nov. 3. But even now, every match counts as we're in the second year of using Michigan Power Ratings (MPR) to determine seeding of the top two teams in every District. Click to link above to see how teams stack up not only in their entire Division but also in their District with pairings set to be assigned Oct. 26.
Records, results and schedules below are those posted for teams on MHSAA.com. Rankings 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. Plymouth Christian Academy d. Mendon (25-12, 25-12) A 5-0 day for Division 3 No. 3 PCA (24-5-0) at the Division 3-4 Showdown included this most notable win over the Division 4 top-ranked Hornets (21-3-1).
2. Farmington Hills Mercy d. Utica Eisenhower (17-25, 25-13, 15-13) After losing the first set, Division 1 No. 3 Mercy (12-2-0) rebounded to even the score and then hold off No. 6 Eisenhower (19-2-1) in the match decider at the Motor City Power Series.
3. Mendon d. Battle Creek St. Philip (25-18, 16-25, 25-16, 25-21) Coming off a 3-2 run at the Division 3-4 Showdown, Mendon continued to justify its Division 4 No. 1 status with this win over the No. 3 Tigers (16-9-4).
4. Battle Creek Lakeview d. Grand Rapids Catholic Central (19-25, 25-18, 15-10) Lakeview (25-5-5) finished 4-0-1 at its invitational, with the tie also against the Division 2 No. 6 Cougars (19-8-1) before winning the rematch in three sets.
5. Grand Rapids South Christian d. Frankenmuth (25-16, 28-26) This Motor City Power Series matchup pitted the Division 2 No. 8 Sailors (14-7-0) and now-No. 10 Eagles (9-6-4), who entered the weekend ranked Nos. 8 and 7, respectively.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Byron Center (19-4-0) The Bulldogs went 13-2 in September and remain an honorable mention in the latest poll after an open weekend. They most recently went 4-0 at their Cristi Curtis Memorial Invitational, and their losses this fall have come against No. 1 Rockford, No. 5 Jenison, No. 8 Grand Rapids Forest Hills Northern and honorable mention Lowell. Byron Center will get a second chance against Jenison on Oct. 16.
Cadillac (18-3-0) The Vikings have begun another march through the Big North Conference – most notably with a five-set win over Traverse City Central on Monday – and they own solid early wins over Division 3 No. 8 Traverse City St. Francis, honorable mention McBain and Division 4 Ubly. The losses came to Division 3 No. 2 Roscommon, No. 4 Kingsley, and Mount Pleasant, all in weekend tournament play.
DIVISION 2
Kingsford (12-0-0) Despite graduating all-stater Madelynn Kreider in the spring, the honorable mention Flivvers are continuing a pace that took them to a 31-5 finish and District title a year ago. The most notable wins so far have come over Division 4 No. 10 Hancock during a 6-0 day at Kingsford’s season-opening invitational and then Calumet on Sept. 11, and they’ll see Negaunee for a second time Thursday after sweeping the Miners during opening weekend.
Milan (10-4-0) The Huron League is loaded this season with Monroe St. Mary Catholic Central again ranked No. 1 in Division 3 and Flat Rock coming off a win over the Kestrels last week. Add Milan to the mix, with losses only to another league foe New Boston Huron, plus SMCC, Division 2 No. 7 Tecumseh and honorable mention Parma Western. The Big Reds won their first meeting with Flat Rock and have a nice victory over Division 3 honorable mention Bronson as well.
DIVISION 3
Kalamazoo Christian (17-6-3) Coming off last year’s run to the Division 3 Semifinals, the No. 6-ranked Comets are facing a schedule filled with Division 1 and 2 teams. They’ve won 10 of their last 12 matches, the defeats coming two weeks ago at the Battle Creek Lakeview Invitational to Division 1 Portage Northern and Division 2 Chelsea. The only loss to a non-D1/D2 opponent came during a season-opening invitational to No. 5 Pewamo-Westphalia, which K-Christian also defeated that day.
McBain (11-7-0) The honorable mention Ramblers have won nine of their last 10 matches as they settle into Highland Conference play with the biggest coming up Thursday against No. 2 Roscommon – which defeated McBain in tournament play Aug. 29 and also ended the Ramblers’ 2024 run in the Regional Finals. McBain already has avenged an early loss this fall to honorable mention Manton and will see the Rangers again Oct. 28. The other defeats came three times to No. 4 Kingsley and once to Calumet and Cadillac.
DIVISION 4
Fowler (13-5-1) A Regional finalist last season, Fowler will definitely be prepared for top competition during tournament time. The Eagles started this season defeating current honorable mention Onekama and have taken losses to Division 1 Portage Northern, Division 3 No. 3 Plymouth Christian Academy, Division 4 No. 2 Ubly (twice) and No. 5 Mount Pleasant Sacred Heart. Fowler also tied and then defeated Division 1 Midland Dow at the start of September. The Eagles will get their next major challenge Thursday at Pewamo-Westphalia.
Ishpeming (12-2-1) An opening draw with Newberry and losses to Negaunee and Calumet are the only flaws during an otherwise excellent start. Ishpeming then defeated Newberry at the Rudyard Invitational and will have a chance to see Negaunee again as well. Unranked at this time, the Hematites could equal last season’s 16 wins by the end of this weekend at the Escanaba Elks Invitational, where most notably they’ll see No. 8 Crystal Falls Forest Park.
Can’t-Miss Contests
Be on the lookout for results of these matches and tournaments coming up:
Thursday – Fowler at Pewamo-Westphalia – A pair of top 10 teams top the Central Michigan Athletic Conference standings as P-W (16-5-3) is No. 5 in Division 3 and Fowler (13-5-1) is No. 6 in Division 4.
Saturday – Motor City Power Series at UWM Sports Complex in Pontiac – The most intriguing pool this weekend includes Division 1 No. 2 Bloomfield Hills (23-2-1), honorable mention Dexter (10-1-0), Novi (13-7-0), Saline (13-5-0) and Lake Orion (12-12-1).
Saturday – Pontiac Notre Dame Prep quad – The Fighting Irish (17-10-1) welcome Division 2 honorable mention Edwardsburg (19-7-0), Birch Run (18-6-2) and West Bloomfield (7-4)
Tuesday – Lansing Catholic at Ionia – Lansing Catholic (14-3-1) fell out of the Division 2 honorable mentions this week, but Ionia (19-3-0) moved up to No. 9.
Tuesday – South Lyon at South Lyon East – These neighbors and Milford head into the final week of the Lakes Valley Conference schedule vying for the top spot, with Division 1 honorable mention South Lyon (21-5-0) undefeated in league play and East (23-5-1) with just a loss to Milford.
