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 3 Report

We’re having a party, and volleyball fans everywhere are invited.
Volleyball has become Michigan’s most popular girls high school sport, with nearly 20,000 high school players last season. “Block Party” is our newest MHSAA.com endeavor, and we’ll be providing glances at some of the best and brightest on courts all over the state during the buildup to our annual Finals weekend at Battle Creek’s Kellogg Arena.
We hope these weekly reports – as they have for football and basketball – shine more light on the week-in, week-out competition that shapes every season, and on programs you may already know about but also several more than maybe you’ll read about for the first time.
This season's first matches were played Aug. 20, making this the midst of our third week (and hence, our Week 3 Report). Records, results and schedules below are based on what’s posted for teams and used to calculate Michigan Power Ratings (MPR) on MHSAA.com. Rankings noted below 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. North Branch d. Monroe St. Mary Catholic Central (25-17, 25-19) The Division 2 No. 3 Broncos finished 6-0 at the Pontiac Notre Dame Prep Invitational, with this toppling of the No. 2-ranked team in Division 3 its best victory.
2. Rockford d. Grand Rapids Christian (25-19, 25-21) The Rams downed the Division 2 No. 2 Eagles and also No. 7 Grand Rapids South Christian among other notables during its Rockford Rumble.
3. Traverse City St. Francis d. Roscommon (25-23, 23-25, 25-20) The Division 3 No. 8 Gladiators’ win over top-ranked Roscommon made a big wave, although St. Francis did also fall to Division 1 Midland Dow on this night.
4. Bloomfield Hills Marian d. Utica Eisenhower (29-23, 19-25, 15-9) This was arguably Division 1 No. 3 Marian’s most impressive win during a MI Elite Program Cup run that also included a two-set sweep of No. 9 Brighton. Eisenhower was ranked No. 6.
5. Monroe St. Mary Catholic Central d. Imlay City (25-18, 20-25, 15-11) SMCC’s only loss at Notre Dame Prep was to North Branch (above), and the Kestrels earned a notable victory over Division 2 No. 5 Imlay City along the way.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Bloomfield Hills (15-1-0) The No. 4-ranked Black Hawks did suffer their first loss of the season last week – in two sets to Marian. But they’ve otherwise have been unbeatable with wins over No. 5 Farmington Hills Mercy, honorable mentions Lake Orion and Novi and another Tuesday over Orchard Lake St. Mary’s, which ended Bloomfield Hills’ season last fall in a District Final. The Black Hawks will see Marian again Thursday.
Rockford (16-0-0) As noted above, the top-ranked Rams cruised through their Rockford Rumble, never dropping a set during victories over South Christian, East Grand Rapids, Grand Rapids Christian and Division 1 honorable mention Mattawan. The win over the Eagles was Rockford’s second this fall; they’ve also downed No. 8 Grand Haven, honorable mention Byron Center and Division 2 No. 4 Holland Christian among several impressive squads over the first three weeks.
DIVISION 2
Grand Rapids Christian (7-4-0) The Eagles’ losses have all come to ranked Division 1 teams – twice to Rockford and once apiece to Grand Haven and honorable mention Hudsonville. Meanwhile, Grand Rapids Christian defeated Division 1 No. 7 Jenison and Mattawan at Rockford over the weekend, and most recently Grand Rapids South Christian and Holland Christian at a power-packed tri last week. South Christian had ended the Eagles’ season with a five-set Regional Final loss last year.
Parma Western (9-0-1) The Panthers will pick up Thursday after a two-week match break and are ranked No. 10 in Division 2 coming off last season’s Regional Final run. Their only non-win was a two-set draw with Division 4 honorable mention Adrian Lenawee Christian, and wins over Division 3 No. 4 Pewamo-Westphalia to start the season and No. 9 Hanover-Horton at the Chelsea Invitational stand out most. Parma Western will see No. 9 Tecumseh on Thursday.
DIVISION 3
Monroe St. Mary Catholic Central (10-1-1) The reigning Division 3 champion is off to another fast start, with that loss to North Branch over the weekend and an early two-set tie against New Boston Huron their only non-victories this fall – and the Kestrels have defeated Huron twice since including 25-18, 25-17, 25-12, on Tuesday. SMCC has lost only four sets total, and only one during an eventual match win.
Saginaw Valley Lutheran (9-2-1) The Chargers aren’t ranked at this time but may get some looks soon. They opened the season with a loss to Division 4 No. 7 Crystal Falls Forest Park at the Mount Pleasant Sacred Heart Invitational, but came back to defeat the Trojans in the semifinals that day before falling to still-undefeated Division 1 Greenville in the championship match. Valley Lutheran has lost only one set over six matches since, to Division 2 Williamston at the Owosso Tournament where the Chargers finished 4-0-1.
DIVISION 4
Hancock (8-1-1) The Bulldogs have followed up last season’s run to the Division 4 Semifinals with a fast start, finishing 4-1-1 at the Kingsford Invitational against a field including several larger opponents after finishing 1-2-1 at the same event in 2024. Hancock will have another chance to improve on last season when it heads to The Rock Invite on Saturday at Gladstone – where it went 1-1-1 in 2024.
Mendon (12-1-1) The Hornets are coming off their toughest weekend of these first few, having finished 3-1-1 at the Cereal City Classic with a loss to Division 1 Battle Creek Lakeview and draw with Division 2 Pennfield but wins over Division 1, 3 and 4 opponents. They also opened the fall with a 5-0 run through the St. Joseph County Tournament as they look to build on last season’s Regional Final run.
Can’t-Miss Contests
Be on the lookout for results of these matches and tournaments coming up:
Wednesday – Flint Powers Catholic (7-5-1), Yale (14-2-0), Traverse City St. Francis (9-6-0) at Essexville Garber (9-6-2) – This quad features the No. 8 team in Division 3 – St. Francis – and the Division 2 honorable mention Dukes.
Thursday – Fowler (7-2-1) at Mount Pleasant Sacred Heart (8-3-3) – The Division 4 top-ranked Eagles visit No. 8 Sacred Heart, which reached the Semifinals last season.
Thursday – Frankenmuth (3-3-4), Rochester (1-6-0), Temperance Bedford (9-1) at North Branch (11-0-0) – In addition to North Branch being ranked No. 3 in Division 2, Frankenmuth is No. 8 and Bedford always is a top team in Division 1.
Saturday – Motor City Power Series at UWM Sports Complex in Pontiac – Division 1 No. 4 Bloomfield Hills, honorable mention Northville, previously-mentioned North Branch, Canton, and White Lake Lakeland will make for an intriguing field.
