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."

Few sports dominate school-year weekends like girls volleyball does with its Saturday tournament schedules each fall.
This past week's again included several events, most notably the East vs. West Challenge (won by the East 11-9) at Brighton's Legacy Center. This weekend could be even bigger with teams from all four divisions locked up in elite competition; see below for plenty of notes referencing some of the best matchups to come.
Records and results are based on what is submitted to MHSAA.com for Michigan Power Ratings (MPR) that determine seeding of the top two teams in every District. 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. South Lyon East d. Rockford (25-22, 25-22) Although South Lyon East (21-5-1) did also lose to Jenison at the East vs. West Challenge, the Cougars made the biggest wave by handing Rockford (20-1-0) its lone loss this season – and moved up to No. 8 in Division 1 this week.
2. Flat Rock d. Monroe St. Mary Catholic Central (25-20, 22-25, 22-25, 25-22, 15-11) Flat Rock (18-4-0) has won 15 of its last 16 matches and now owns its first win – ever – over Monroe St. Mary (13-2-1).
3. Farmington Hills Mercy d. Bloomfield Hills Marian (14-25, 25-22, 25-22, 27-25) These rivals should meet at least a few more times this fall, but Mercy (8-2-1) handed Marian (23-2-0) just its second match loss and despite falling in the first set.
4. East Grand Rapids d. Grand Rapids Christian (25-19, 25-20) The Pioneers (20-5-0) finished 5-0 at the Lake Odessa Lakewood Invitational, with this win over last week’s No. 2 team in Division 2 likely helping to jump them onto the Division 1 honorable mention list.
5. Brighton d. Northville (25-16, 25-22, 25-22) In a matchup of Division 1 honorable mentions, Brighton (18-3-0) defeated reigning champion Northville (6-6-0) for the first time since 2019.
Watch List
With an eye toward November, here are two teams in each division making sparks:
DIVISION 1
Farmington Hills Mercy (8-2-0) The Marlins – Division 1 champions most recently in 2023 and ranked No. 3 this week – are again among the elite coming off a 2-1 run at the East vs. West Challenge. Mercy defeated Division 1 honorable mention Lowell and Muskegon Mona Shores and lost to top-ranked Rockford there, but its only other defeat came to Division 1 No. 2 Bloomfield Hills a month ago. Mercy opened last week with the big Marian victory noted above.
Jenison (19-2-0) A 4-0 run through the East vs. West Challenge included sweeps of Brighton, Northville, South Lyon East and Grosse Pointe South as Jenison moved up to No. 5 in Division 1. The Wildcats – Regional finalists last season – also have downed Division 1 honorable mention Byron Center and Division 2 No. 8 Grand Rapids South Christian and split with Division 1 No. 9 Grand Rapids Forest Hills Northern, the other defeat coming to Division 2 No. 3 Grand Rapids Christian.
DIVISION 2
Lansing Catholic (13-1-1) The Cougars received an honorable mention in the Division 2 poll this week coming off a 4-0 run through the Mt. Morris Invitational. Lansing Catholic also went 3-0-1 at the Bay City Western Tournament to start the season – getting a win over Midland after previously tying the Chemics that day. Lansing Catholic suffered its first loss Tuesday, to Portland.
North Branch (21-2-0) The 2022 and 2023 Division 2 champion reached the Quarterfinals last year and is blasting through another tough schedule in preparation for another potentially big run. The Broncos moved up a spot to No. 2 in the rankings this week after defeating Mona Shores, Lowell and Grand Rapids Northview at the East/West, and their only losses this season were to Northville and Bloomfield Hills the weekend before. They’ve downed Division 2 No. 7 Frankenmuth and Division 3 top-ranked SMCC among several others.
DIVISION 3
Hanover-Horton (16-1-1) A 6-0 run through the weekend’s Spring Arbor University Invitational was topped off by the No. 7 Comets sweeping Division 2 honorable mention Parma Western in the clincher. That actually also avenged Hanover-Horton’s only loss, in three sets, during the season-opening Chelsea Invitational where the Comets went 2-1-1 against Division 1 and 2 teams. They also count a pair of wins over Division 4 Concord among their most notable.
Plymouth Christian Academy (18-5-0) The Eagles are holding steady at No. 3 in Division 3 coming off a 4-1 run against Division 1 and 2 opponents at the weekend’s Portage Northern Invitational. A Regional finalist as well a year ago, PCA opened this season with a championship at the Leland Invitational against a field that also included Division 2 honorable mention Marshall, and got more valuable matches against Division 1 and 2 opponents at two more tournaments.
DIVISION 4
Lake Linden-Hubbell (17-2-0) The Lakes have won the Copper Mountain Conference Preseason Tournament and finished second at the Baraga Invitational on the way to already approaching last season’s 22-12-0 record. The lone losses came to No. 10 Hancock in four sets and Chassell at the Baraga event, and they’re set to see both again at least once more – home against Chassell next Monday and at Hancock on Oct. 21. All three are in the same District as well.
Ubly (10-2-2) The Bearcats jumped three spots to No. 2 in Division 4 this week as they seek to build on last season’s 37-8-0 finish and Quarterfinal run. Ubly went 4-0-2 at the weekend’s Eaton Rapids Tournament, twice defeating then-No. 2 Fowler plus honorable mention Adrian Lenawee Christian, which jumped to No. 4 this week. The defeats this season were solid as well, both coming during the opening weekend at the Cadillac Invitational to the Division 2 Vikings and Division 3 No. 8 Traverse City St. Francis.
Can’t-Miss Contests
Be on the lookout for results of these matches and tournaments coming up:
Thursday – Onekama (12-4-0) at Suttons Bay (13-0-0) – Both are honorable mentions in Division 4, and the winner could push for a spot among the top 10.
Saturday – Motor City Power Series at UWM Sports Complex in Pontiac – A total of 28 teams will play as the Power Series reconvenes, including a pool with Division 1 No. 3 Mercy, No. 6 Utica Eisenhower, honorable mention Brighton, Traverse City Central and Division 2 No. 2 North Branch.
Saturday – D3 & D4 Showdown at Schoolcraft College in Livonia – This bracket will feature Division 3 No. 5 Pewamo-Westphalia and honorable mention Cass City, and Division 4 top-ranked Mendon and No. 2 Ubly among others.
Saturday – Battle Creek Lakeview Invitational – Division 2 No. 6 Grand Rapids Catholic Central might be the headliner, but host Lakeview, Detroit Renaissance, Otsego and Coldwater are among other intriguing teams in the field.
Tuesday – Hancock (14-2-2) at Negaunee (11-4-2) – These two split at the season-opening Kingsford Invitational, and this matchup will mean more with Western Peninsula Athletic Conference ramifications.
