Performance: Grand Haven's Kathryn Ackerman
November 27, 2019
Kathryn Ackerman
Grand Haven senior - Swimming
The Buccaneers’ standout will graduate next spring as one of the most accomplished athletes in Grand Haven history and one of the top high school swimmers in Michigan all-time. She won her fourth and fifth individual MHSAA Finals championships at Saturday’s Lower Peninsula Division 1 Finals at the Holland Aquatic Center to earn the MHSAA “Performance of the Week” – and ranks among the nation’s fastest high school swimmers in both of her events this fall.
Ackerman earned her third straight championship in the 200-yard individual medley (1:57.61) and won the backstroke (54.70) for the second-straight year. She also teamed with senior Alonna Clark and juniors Ocean Veldhouse and Mary Violet Springer on the runner-up 400 freestyle relay (3:27.92) and with Springer, Veldhouse and junior Georgia Basil on the ninth-place 200 medley relay (1:47.58). Her IM time was the second-fastest in MHSAA Finals history, from all divisions/classes, behind her record-setting time from 2018. The superiority in the IM is evidence of her impressive versatility – she holds Grand Haven records in that race but also the 200 and 500 freestyles, butterfly, backstroke and breaststroke, and has been part of all three school-record relays. Grand Haven as a team finished seventh at Saturday’s Finals, up from 10th a year ago, 12th her sophomore year and 15th when she was a freshman in 2016.
Next up for Ackerman will be another club season as she prepares to swim at next summer’s Olympic Trials and then join University of Michigan’s program, which finished third at last season’s NCAA Championships. She expects to swim the 200 and 400 IM races, freestyle and backstroke moving forward, with an eye on also competing at the 2024 Olympic Trials. Her IM time from Saturday is the fastest by a high school swimmer in the nation this fall according to swimcloud.com, and her backstroke time ranks 12th nationally. Ackerman, who also played high school tennis as a freshman, carries a 4.11 grade-point average that places her among the top 15 academically in her graduating class at Grand Haven. Math and science always have been her strengths – and she’s planning to study engineering at U-M.
Coach Doug Thorne said: “Kathryn is by far one of the most passionate, but humble student-athletes I've ever coached. Her love for the sport is like no other.”
Performance Point: “I think the biggest thing was just having the chance to spend my last high school state meet with the girls that I started swimming with – I’ve been swimming with some of the same girls since I was 8 years old, so it was bittersweet,” Ackerman said. “But it was a lot of fun to finish off the meet with the 400 freestyle relay where we were runner-up, and to swim to those two championships was a lot of fun too. To finish off on that note was good.”
Go Bucs: “High school sports have been incredible. Going into high school swimming, I wasn't expecting to accomplish this much just because I've been so familiar with club sports my entire life. To go through these four championship meets and set records, and experience all of these accomplishments that I have, it's been incredible and I wouldn't ask for anything more from high school sports. … (I’ll miss most) the team and the team atmosphere. The girls are so supportive and encouraging at every meet. They're behind the lane, cheering you on, and always wished me good luck before races. So I'll definitely miss the team and obviously the coaches and everyone that surrounds that sport too.”
Go State to Go Blue: “Actually, my entire family, they’re pretty big Michigan State fans. So it’s kinda hard to make the switch (to U-M), but just recognizing that Michigan has such an excellent swim program and school made it easier to make the switch. My family is supportive of anything I do.”
Plan to succeed: “Growing up, I always just focused a lot on my stroke technique. It wasn’t always about swimming the most yards, or high-intensity workouts. It was about doing drills and starting that foundation so I could go faster in high school. It definitely paid off in these four years … and the times that I have right now are looking really good going into Michigan. So I’m looking forward to the next chapter, but I definitely have to thank all of my coaches for all of the work that they’ve done for me. I appreciate all of them and the support they’ve shown me throughout this process too.”
Learning to lead: “There have been some girls that I've swam with on my club team in Holland, and they have always been so encouraging and supportive of their teammates. I not only look up to them for their characteristics of being supportive and encouraging, but they're also super hard-working, and they're fast, so I've always had them as role models. … It's helpful to have someone who has been that kind and supportive to me. They've exemplified so well what a good leader is. It was helpful to have that foundation as I went through high school and was the leader of the younger girls. (Also) my older sister Anna was on the high school team through her four years too, and she was elected as a captain her junior and senior year. S I also learned a lot from my sister on how to be a supportive and encouraging teammate. A lot (of credit) goes out to my sister as well.”

Grand Blanc Takes 'Total Team Effort' to Championship Level with SVL Title Clincher

Needing a “total team effort” was much more than generic coach speak this past week for the Grand Blanc girls swimming & diving team.
Twenty-one athletes scored at the Saginaw Valley League Championships, helping the Bobcats edge Midland Dow and claim the program’s first league title since 2020.
“I definitely think that’s what sets us apart from other teams – we have so many amazing swimmers,” Grand Blanc senior Riley McLeman said. “If we had two people in the championship heat, and so did Dow, we also had two people in the B and C finals, where they had none. Everyone played a role in this. Every single person on our team was important, and that was amazing to see.”
Quality depth has driven the Bobcats all season, and in the SVL meet, it was the difference as they overcame Dow placing the individual winner in eight of the meet’s 12 events. Grand Blanc did win two events and placed second in nine, but pulled away with its depth.
“We knew early on in the season that we were keeping a really great senior class and had a lot of great swimmers returning, and also that we were getting a great freshman class,” Grand Blanc coach Katherine Kuhn said. “We had our sights set on winning leagues, and we knew we had that depth and that speed. And they had to show out. It wasn’t just, ‘We have this depth, we’re good.’ They still had to really show out at the meet, and they did.”
The SVL meet scores all the way through 24 places, adding importance to the B and C finals.
So, for a swimmer like freshman Ava Christian, her personal-best times in the 200 and 500-yard freestyle races were for more than just pride as she contributed to the Grand Blanc cause with 33 points – all earned in B finals.
“There was kind of some pressure, but it was a good pressure,” Christian said. “Even people that weren’t scoring as highly still had a chance to make a difference. It put pressure on everyone, not just the top swimmers. I really feel like it shows how well we can work together and support each other.”
The top swimmers did their job, as well. Rory Grzymkowksi won the 100 backstroke, while Mallory Shaver, Norah Grosso, Peyton Folks and Sydney Folks won the 400 free relay. Shaver was second in the 200 and 500 freestyles, while McLeman was second in the 100 breaststroke and 200 individual medley and Lila Brocker was second in the 100 backstroke. The 200 free and 200 medley relays also placed second.
Just as fun for that group of standouts was cheering on their teammates in those B and C finals, knowing how much they meant.
“It was great,” McLeman said. “Especially watching some of these freshmen that I didn’t know too well before the season, and even some of my best friends I’ve been swimming with for years getting to compete at a high level and having these amazing breakthrough races. It really got us hyped up and excited for our races.”
While building its depth, Grand Blanc has also been getting stronger at the top. Eight swimmers will be competing at the Lower Peninsula Division 1 Finals on Nov. 21 and 22 at Oakland University. McLeman, Shaver, Sydney Folks, Grzymkowski and Brocker all have qualified in individual events, while Cameron Folks, Peyton Folks and Grosso will swim on relays. Diver Chloe Borton has a chance to make it nine qualifiers, as she will compete at her event Regional on Thursday.
It’s a number Kuhn said she hasn’t seen in her five years (three as an assistant, two as head coach) with the varsity program.
The goal for the Bobcats is to get as many athletes as possible to the final day of the season, something Shaver was able to do a year ago as a sophomore.
“There are some first-time people, and some people that know what to expect, but I definitely will share with the freshmen that they have to take it in and not let the stress take over, because they’ve trained for this,” Shaver said. “I think we have some talented girls that have been able to put in the work and want to represent Grand Blanc in a good way and just show off our talents.”
If the trend of this season holds, expect the Bobcats to reach that goal, as they’ve reached every one to this point.
McLeman said Kuhn broke the season into chunks for the team:
Win the Genesee County meet. Check.
Defeat Dow in a dual. Check.
Win the SVL. Check.
“It’s just been great; it’s been the most amazing season I’ve been part of,” McLeman said. “I could not ask for a better way to finish up my Grand Blanc swim career, to watch me and my best friends accomplish something we’ve worked for since our freshman year.”
