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."

A volleyball season full of weekend excitement will again enjoy one of its most attention-grabbing highlights Sunday.
More than two months of matches will boil down to the selection of first and second seeds for every District bracket, with MHSAA Tournament play set to begin a week later on Nov. 3.
Seeds are determined by Michigan Power Ratings (MPR), and as noted previously you can follow how teams stack up statewide, in their respective divisions and even in their respective Districts on the MPR page. The formula for determining the rest of the District is posted here.
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. Kingsley d. Traverse City St. Francis (25-22, 25-15) The Division 3 No. 3-ranked Stags (44-4-1) went 5-0 at the McBain Tournament, defeating honorable mentions McBain and Beal City as well but topping the day with this sweep of the No. 8 Gladiators (24-14-0).
2. Hudsonville d. Grand Haven (25-20, 27-29, 20-25, 25-18, 15-11) The Division 1 No. 9 Eagles (27-8-1) prevailed after falling behind 2-1, avenging a pair of previous losses to the No. 8 Buccaneers (33-9-0) from Sept. 25 and Oct. 4.
3. Crystal Falls Forest Park d. Kingsford (25-15, 25-14, 25-21) The Division 4 No. 5 Trojans (35-1-0) continued to justify their status among the Upper Peninsula’s best regardless of division, with this win over the Division 2 honorable mention Flivvers (19-2-0) – during a 3-0 day at the Clash of the Divisions – one of their most impressive this fall.
4. Grand Haven d. Grand Rapids Catholic Central (25-17, 25-19) Three days before the Hudsonville loss, Grand Haven went 4-0 at the Mattawan Invitational with this win over the Division 4 No. 5 Cougars (30-10-1) arguably the best although the Bucs also downed Division 1 honorable mention Byron Center.
5. Hancock d. Lake Linden-Hubbell (25-12, 22-25, 25-14, 27-25) The Division 4 No. 8 Bulldogs (23-3-2) followed up a big sweep of Ishpeming with this win over Lake Linden-Hubbell (22-5-0) to further firm up their place among the best in the Upper Peninsula and Division 4 as a whole as well.

Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Brighton (25-6-2) The Bulldogs are holding onto an honorable mention in the latest Division 1 rankings with a run of nine wins over their last 12 matches and their losses this season coming to an incredible group of No. 1 Rockford, No. 2 Farmington Hills Mercy, No. 3 Bloomfield Hills Marian, No. 7 Utica Eisenhower (twice) and honorable mention Jenison. Brighton clinched the Kensington Lakes Activities Association West title and will play Northville in the KLAA Gold Tournament championship match Saturday. The Bulldogs also are slated for a top seed in their District.
South Lyon East (30-7-1) The No. 10-ranked Cougars finished 4-0 at the final Motor City Power Series last weekend, highlighted by a 2-1 win over Division 2 No. 3 North Branch. All but one of their losses have come to a top-10 or honorable mention team in Division 1 as well, and they remain the only team to defeat top-ranked Rockford. East followed up that Sept. 20 win by defeating Division 2 No. 2 Detroit Country Day as well, and is tied for first in the Lakes Valley Conference with the league tournament coming up Saturday.
DIVISION 2
Flat Rock (22-6-0) A Sept. 22 win over Monroe St. Mary Catholic Central – the program’s first against the Huron League foe – put Flat Rock into the spotlight this fall, and it has received honorable mention again this week in the Division 2 poll. But the Rams have much more to boast, including a victory over Kingsley, and have also built up their experience in losses most recently to No. 6 Tecumseh and honorable mention Milan. Tune in for tonight’s for the rematch with the Kestrels.
Grand Rapids Catholic Central (30-10-1) After opening this season with three losses at the Traverse City West Invitational, the Cougars have strung together plenty of success including 13 victories over their last 15 matches. They did fall to Grand Haven over the weekend at Mattawan but defeated DeWitt, Portage Central and Division 3 No. 7 Kalamazoo Christian and moved up a spot to No. 4 in this week’s Division 2 rankings. They’ve already far surpassed last year’s 23-22-2 finish, with a likely top seed awaiting in their District as the only team in the bracket with a winning record.
DIVISION 3
Kalamazoo Hackett Catholic Prep (17-3-2) The Fighting Irish are not ranked currently but may draw some notice with a 9-1-2 run that’s included a 25-23, 28-26, sweep of Division 4 No. 6 Battle Creek St. Philip and just a three-set loss to Division 2 Buchanan after Hackett won the first set. The Irish are lined up right now as the likely second seed in their District opposite No. 7 Kalamazoo Christian, which defeated Hackett in last year’s District Final and this season on Sept. 23. The only other loss this fall came to Delton Kellogg.
Pewamo-Westphalia (24-7-3) The 2022 Division 3 champion – and a quarterfinalist the last two seasons – No. 6 P-W is riding a seven-match winning streak as it gears up for another potential run. The best win over these last few weeks was a 2-1 comeback victory over No. 2 Plymouth Christian Academy at the Mt. Morris Tournament, and wins over No. 7 Kalamazoo Christian, No. 9 Saginaw Valley Lutheran and Division 2 No. 10 Battle Creek Harper Creek also stick out from this season’s overall work.
DIVISION 4
Midland Calvary Baptist (23-5-1) The Kings need two more wins to equal the total from last year’s Regional finalist team, and on Saturday went 4-1 at the Tawas Tournament with especially notable victories over Division 3 Johannesburg-Lewiston and Alcona and the loss to Division 2 Ogemaw Heights. All of Calvary Baptist’s defeats and the one tie came against Division 2 or 3 opponents, and as of today the Kings are slated to be the top seed in a District bracket that also includes No. 6 Mount Pleasant Sacred Heart.
Onekama (23-7-2) The Portagers are 9-2-2 over the last two-plus weeks and an honorable mention in this week’s rankings as the prepare to attempt next month to extend a five-year District title streak. They went 3-1-1 at the Farwell Paula Sullivan Tournament over the weekend, tying and then falling to Division 3 No. 10 Manton. But Onekama has solid wins over honorable mention Suttons Bay and Manton from earlier this season and plenty of other tough losses as well.
Can’t-Miss Contests
Be on the lookout for results of these matches and tournaments coming up:
Wednesday – Davison (24-4-0) at Mount Pleasant (25-6-1) – Both went undefeated in their divisions and earn their spots in this overall Saginaw Valley League championship match.
Wednesday – Carrollton (27-1-2) at Saginaw Valley Lutheran (35-8-3) – This is a winner-take-all matchup for the Tri-Valley Conference Blue regular-season championship.
Saturday – Lowell East vs. West Challenge – The 16-team field includes Division 1 top-ranked Rockford, No. 2 Farmington Hills Mercy, No. 3 Bloomfield Hills Marian, No. 4 Bloomfield Hills, No. 5 Lowell, No. 7 Utica Eisenhower and honorable mentions Jenison, Byron Center and Clarkston among several others.
Tuesday – Detroit Country Day quad – The Division 2 No. 2 Yellowjackets (13-7-0) will welcome Marian (34-4-0), Eisenhower (30-3-1) and Fenton (15-10-0).
Tuesday – Beal City (28-7-0) at Roscommon (42-2-0) – Division 3 top-ranked Roscommon can finish a perfect run through the Highland Conference, but honorable mention Beal City hopes to stand in the way.
