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."

Just as the girls volleyball regular season begins speeding toward its conclusion, clicks on our Michigan Power Ratings (MPR) page are sure to accelerate over the next three weeks.
District play begins Nov. 2, and brackets will be announced eight days earlier on Oct. 25. MPR is used to seed the top two teams in every District, and although there’s only one example below, references to how teams stack up on those lists will become more prevalent in our weekly reports as we close in on the start of the playoffs.
Records below are those reported and tracked on this website, and rankings referred to 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. Saginaw Valley Lutheran d. Plymouth Christian Academy (25-21, 25-17) The Division 3 top-ranked Chargers (36-4-1) finished 6-0 at the D3/D4 Showcase, with this win arguably the most notable as Valley Lutheran remains No. 1 statewide this week but PCA (21-6-4) bumped up from honorable mention to No. 2.
2. Grand Rapids Christian d. Hudsonville (25-19, 25-19) Division 2 top-ranked Christian (22-3) avenged a pool play loss to Division 1 No. 5 Hudsonville (26-3) at the Jenison Invitational to win this rematch in the championship round.
3. Orchard Lake St. Mary’s d. Detroit Country Day (25-19, 25-16, 25-23) The Division 1 honorable mention Eaglets (13-8-1) continued their climb with a sweep of the two-time reigning Division 2 champion and current No. 2 Yellowjackets (12-6-1).
4. Kingsley d. Elk Rapids (25-15, 25-17, 25-11) This Northern Shores Conference matchup saw a pair of ranked teams face off and the Division 2 No. 5 Stags (29-3-1) prevail over the Division 3 No. 5 Elks (13-7-3).
5. Muskegon Western Michigan Christian d. Hart (24-26, 27-25, 25-18) While Division 3 No. 3 WMC went on to defeat Fruitport and Muskegon Mona Shores to win the latter’s Best of the West tournament, this win over No. 10 Hart (19-10-3) sticks out as well as the Warriors (23-2) came back after losing the first set.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Grand Rapids Forest Hills Northern (22-8) The honorable mention Huskies opened this week with a notable four-set victory over honorable mention East Grand Rapids, which is listed ahead of FHN in Division 1 MPR. Six of Forest Hills Northern’s losses have come against top-10 teams in Division 1, and six wins have come against opponents ranked or honorable mentions in Divisions 1 or 2, including Division 1 No. 4 Byron Center.
Hudsonville (26-3) The No. 5 Eagles were runners-up at the Jenison Invitational thanks to a split with Division 2 top-ranked Grand Rapids Christian, but that championship match defeat broke a 13-match winning streak. The Eagles’ only other losses have come versus Brighton and Division 1 No. 2 Bloomfield Hills Marian, and Hudsonville has defeated No. 8 Lowell, honorable mention Forest Hills Northern twice, No. 4 Byron Center, No. 9 Grand Haven, No. 7 South Lyon East, honorable mention South Lyon twice and GR Christian another time as well.
DIVISION 2
Ann Arbor Father Gabriel Richard (25-3-2) The Irish are an honorable mention in Division 2 and finished second in the Catholic High School League AA to Dearborn Divine Child, thanks to early-September back-to-back league losses to the Falcons and Jackson Lumen Christi. FGR’s only other defeat came to No. 3 Parma Western during opening weekend, and the Irish have won 16 straight matches and their last three tournaments.
Edwardsburg (21-5) The No. 7 Eddies defeated honorable mention Marshall and Division 1 honorable mention Zeeland East over four wins to claim the Portage Central Tournament title on Saturday, and their win over the host Mustangs also avenged Edwardsburg’s most recent loss from Sept. 19. A championship at the Gull Lake Invitational to start this season included a win over Niles, which ended the Eddies’ 2025.
DIVISION 3
Calumet (14-9-1) After opening the season 0-4 at the Cadillac Invitational – which included defeats against Division 1 honorable mention Zeeland East, Division 3 No. 8 Cass City and honorable mention Manton – the honorable mention Copper Kings are 8-2-1 against in-state opponents. They’ve defeated Division 4 No. 7 Crystal Falls Forest Park and went five sets before losing to Division 4 No. 9 Hancock, and they saw more of the state’s best taking a loss but also tying Division 3 No. 2 Plymouth Christian Academy at the D3/D4 Showdown.
Plymouth Christian Academy (21-6-4) The Eagles returned to the Quarterfinals a year ago and are in the midst of an 8-1-1 surge this fall that’s sent them back up to No. 2 in the weekly coaches poll. Their D3/D4 Showdown weekend included the above-noted loss to No. 1 Valley Lutheran but also wins over No. 5 Clinton, No. 8 Cass City and honorable mention Calumet among others. Only two other losses this season came to Division 3 or 4 opponents.
DIVISION 4
Crystal Falls Forest Park (26-3-1) The Trojans reached the Semifinals last season for the third time in four years and haven’t slowed down, falling only to No. 4 Traverse City Christian, No. 9 Hancock and Division 3 honorable mention Calumet. They’re up to No. 7 in the Division 4 rankings while riding a 14-match winning streak and coming off a 6-0 day at the Escanaba Invitational. An opening-weekend trip downstate included the loss to TC Christian but also a win over No. 10 Onekama and tie versus No. 3 Mount Pleasant Sacred Heart.
Traverse City Christian (23-5) The No. 4-ranked Sabres have strung together two straight trips to the Quarterfinals and won their first 10 matches this fall including a three-setter over Division 3 top-ranked Saginaw Valley Lutheran. The losses are pretty impressive as well, to Division 3 No. 3 Roscommon, twice to Division 3 No. 7 Traverse City St. Francis, and then to Division 4 No. 3 Mount Pleasant Sacred Heart and No. 10 Onekama. A home match against Division 3 No. 5 Elk Rapids on Oct. 15 will be another important test.
