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."

Field Hockey Debut, Tennis Finals Change Among Most Notable as Fall Practices Set to Begin

The addition of girls field hockey as a sponsored postseason championship sport and a revised schedule for Lower Peninsula Boys Tennis Finals are the most significant changes to fall sports as practices are set to begin Monday, Aug. 11, for an anticipated 100,000 high school athletes at Michigan High School Athletic Association member schools.

The fall season includes the most played sports for both boys and girls; 36,210 football players and 19,679 girls volleyball players competed during the Fall 2024 season. Teams in those sports will be joined by competitors in girls and boys cross country, field hockey, Lower Peninsula girls golf, boys soccer, Lower Peninsula girls swimming & diving, Upper Peninsula girls tennis and Lower Peninsula boys tennis in beginning practice next week. Competition begins Aug. 15 for cross country, field hockey, golf, soccer and tennis, Aug. 20 for swimming & diving and volleyball, and Aug. 28 for varsity football. 

Field hockey is one of two sports set to make its debut with MHSAA sponsorship during the 2025-26 school year; boys volleyball will play its first season with MHSAA sponsorship in the spring.

There are 37 varsity teams expected to play during the inaugural field hockey season. There will be one playoff division, with the first MHSAA Regionals in this sport beginning Oct. 8 and the first championship awarded Oct. 25.

To conclude their season, Lower Peninsula boys tennis teams will begin a pilot program showcasing Finals for all four divisions at the same location – Midland Tennis Center – over a two-week period. Division 4 will begin play with its two-day event Oct. 15-16, followed by Division 1 on Oct. 17-18, Division 2 on Oct. 22-23 and Division 3 played Oct. 24-25.

Also in Lower Peninsula boys tennis, and girls in the spring, a Finals qualification change will allow for teams that finish third at their Regionals to advance to the season-ending tournament as well, but only in postseason divisions where there are six Regionals – which will be all four boys divisions this fall.

The 11-Player Football Finals at Ford Field will be played this fall over a three-day period, with Division 8, 4, 6 and 2 games on Friday, Nov. 28, and Division 7, 3, 5 and 1 games played Sunday, Nov. 30, to accommodate Michigan State’s game against Maryland on Nov. 29 at Ford Field.

Two more changes affecting football playoffs will be noticeable this fall. For the first time, 8-Player Semifinals will be played at neutral sites; previously the team with the highest playoff-point average continued to host during that round. Also, teams that forfeit games will no longer receive playoff-point average strength-of-schedule bonus points from those opponents to which they forfeited.

A pair of changes in boys soccer this fall will address sportsmanship. The first allows game officials to take action against a team’s head coach in addition to any cautions or ejections issues to players and personnel in that team’s bench area – making the head coach more accountable for behavior on the sideline. The second change allows for only the team captain to speak with an official during the breaks between periods (halftime and during overtime), unless another coach, player, etc., is summoned by the official – with the penalty a yellow card to the offending individual.

A few more game-action rules changes will be quickly noticeable to participants and spectators.  

  •          In volleyball, multiple contacts by one player attempting to play the ball will now be allowed on second contact if the next contact is by a teammate on the same side of the net. 
  •         In swimming & diving, backstroke ledges will be permitted in pools that maintain a 6-foot water depth. If used in competition, identical ledges must be provided by the host team for all lanes, although individual swimmers are not required to use them. 
  •         Also in swimming & diving – during relay exchanges – second, third and fourth swimmers must have one foot stationary at the front edge of the deck. The remainder of their bodies may be in motion prior to the finish of the incoming swimmer.
  •          In football, when a forward fumble goes out of bounds, the ball will now be spotted where the fumble occurred instead of where the ball crossed the sideline.

The 2025 Fall campaign culminates with postseason tournaments beginning with the Upper Peninsula Girls Tennis Finals during the week of Sept. 29 and wrapping up with the 11-Player Football Finals on Nov. 28 and 30. Here is a complete list of fall tournament dates:

The MHSAA is a private, not-for-profit corporation of voluntary membership by more than 1,500 public and private senior high schools and junior high/middle schools which exists to develop common rules for athletic eligibility and competition. No government funds or tax dollars support the MHSAA, which was the first such association nationally to not accept membership dues or tournament entry fees from schools. Member schools which enforce these rules are permitted to participate in MHSAA tournaments, which attract more than 1.4 million spectators each year.
