Coach Bios

Sydney Challoner
Head Coach

I graduated from Sun Prairie High School in 2016, and am now attending college at UW Oshkosh studying Criminal Justice.

I joined Piranhas when I was 5 years old and joined DFAC later that year. I have made it to USA swimming state since age 10, and have qualified for speedo sectionals each year since 2014. I swam all four years in high school, earning a varsity letter each year, and ending my career as a team captain. I continued my swimming career at Madison Aquatic Club since 2016, I also swim collegiately at UW Oshkosh. At our midseason meet at Carthage I finished 1st in the 200 fly, ending the season with a 7th place finish in both the 200 fly and 100 breast at the 2017 WIAC conference.

I have always had a passion for coaching, starting out with helping mini piranhas, and continuing coaching with Special Olympics in 2016. I believe that the technical ability I have developed over the years from club swimming will benefit the Piranhas swim team. I am very excited to be working with such a wonderful team, Go Piranhas!

Jamie McMillin
Assistant and Lead Coach

This is my Eighth year with the Piranhas. I started swimming at 12 years old with the DeForest Aquatic Club (my mom had to sit on deck every practice because I did not know how to swim and she thought I might drown!). I also swam on the high school swim team at DeForest High School. I went on to swim at UW-Stevens Point where I swam the 200 back, 200 breast, and 400IM as well as being Team Captain for my Junior and Senior years. As you can tell, I was not much of a sprinter!

After graduating from UW-Stevens Point with a Sociology Degree, I went to the University of Wyoming where I was the Head Assistant Coach of their program for both the Men and Women's teams. After coaching the Cowboys and Cowgirls, it was time for me to pursue another degree in teaching. I headed back to UW- Oshkosh where I pursued a Masters Degree in Special Education while coaching at UW- Oshkosh.

For the past 15 years I have taught 6th and 7th grade Special Education at Patrick Marsh Middle School as well as coached for Sun Prairie Storm for the past 2 years.

Konrad Plomedahl
Assistant and Lead Coach

My name is Konrad Plomedahl, and I am very excited to be coaching again with the Piranhas this season. Here is a little summary about me and my swimming career.

I have been swimming competitively since 5th grade. I started swimming for the Sun Prairie Piranhas when I moved here in 7th grade. I swam a total of 6 years with the Piranhas. I also swam four years for the Sun Prairie High School Swim and Dive team. My junior and senior year I was captain of the High School team, and in my senior year I qualified for state in 4 events (200 medley relay, 200 free relay and 400 free relay, and 100 fly). I am a current member of the UWEC Swim and Dive team. At the 2016-17 Conference meet, I received 8th place in the 100 fly, and 7th place in the 200 fly. I was also recently selected as a team captain for this upcoming season. I am very proud of my accomplishments as a swimmer, and I hope that I can help all the swimmers this season gain the same sense of pride in swimming as I have.

This will be my 4th season as a coach for the Sun Prairie Piranhas. My other coaching experiences include three seasons with the Sun Prairie Storm, two seasons assisting the Eau Claire Marlins, and I am currently the Head Coach for the Sun Prairie Mini Piranha program. I also have taught many swim lessons and stroke refinement classes.

I am very excited to get to know all of you this season! Get ready for a fun summer!!

Kalie Koch
Assistant and Lead Coach

Kalie is super excited to be part of our Piranha family. She began her swimming career when she was in elementary school swimming for the Pottawatomi Porpoises summer team. Then is 6th grade she started swimming competitively for the St. Charles Swim Team in Illinois. As part of the ST. Charles Swim Team she qualified for Regionals and was a finalist in the mile (4th place) and 1000 Free (7th place). She then was a four-year varsity letter winner, IHSA Upstate Eight Academic All-Conference winner for 3 years, and varsity captain her Senior year at St. Charles High School.

When Kalie was a sophomore in high school she started lifeguarding and teaching swim lessons. As a swim lesson instructor Kalie has worked with all ages from preschool to college level, and all abilities from beginner to experience. You may have seen her at the YMCA in Sun Prairie lifeguarding and teaching swim lessons, where she has been teaching for 3 years.

Kalie started coaching during her sophomore year of high school. She started as a volunteer coach for a Special Olympic Swim Team (Fox Valley Special Recreation Association) and learned new ways of teaching each stroke for all abilities. She coached for this team for three years. During her Junior year of high school, she started to coach for the St. Charles Swim Team: non-competitive branch as an assistant coach. Here she coached for 2 years both the 8 and under team and the 9 and up team. In May 2016 Kalie got her USA Swimming Certification as a coach and started coaching for DFAC as an assistant coach for the 9-13-year old?s, middle school and high school swimmers. Kalie is currently a co-lead coach for the beginner 9-13-year-old team.

As well as coaching, Kalie is currently attending UW Madison. Her major is Elementary Education with hopes of going to graduate school for Secondary Education (she can?t decide who she wants to teach yet). But her dream growing up was to become a History Teacher and also a Swim Coach.

Josie Nettum
Assistant and Lead Coach

My name is Josephine (Josie) Nettum and I am graduating from Sun Prairie High School this June. I started swimming on Piranhas when I was 9. Since then, I swam on DFAC for three years, Sun Prairie Storm for four years, and the high school team all four years. In high school I participated in both JV and Varsity conference and lettered three times. As a senior I ended the season by placing fifth overall in the 100 backstroke at JV conference and swam at Varsity conference.

Over the past year I have started coaching. In the summer of 2016 I was a coach for Mini Piranhas coaching the 9-10 age group. Then in November, after the High School Season, I started coaching for Storm. During the winter session I coached Tropical Storm and this Spring session I am coaching both Tropical Storm and Thunderstorm. I really enjoy coaching and I now understand the technical side of swimming. In addition, I have developed a stronger understanding of the parent perspective of swimming.

I am so happy for the opportunity to have my tenth year as part of the Piranha Swim Team to be a coach!

Clarise Nettum
Assistant and Lead Coach

Hi, my name is Clarise Nettum. I will be graduating from Sun Prairie High School this June. When I was nine years old I joined the Piranhas swim team and have been part of the team ever since. In addition to swimming on the Piranhas, I also swam on the DFAC for three years, Sun Prairie Storm for four years, and four years on the high school team. In high school, I lettered three times. I swam for both JV and Varsity conferences twice. As a senior, I finished my season with a PR in the 100 breaststroke at varsity conference, reaching my goal time.

Last summer I started coaching. I coached first for the Mini Piranhas, working specifically with the eight and unders. After the high school swim season, I started coaching for Storm. During the winter session, I coached the Thunderstorms. Now I coach the Thunderstorm and Tropical Storm in spring season. In addition to coaching, I also have been teaching swim lessons for the past two years, ages two to twelve. This past winter I received my Water Safety Instructor certification. I really enjoy coaching and helping kids improve their skills in the water.

I am so excited to get the chance to coach for the Piranhas swim team! I hope I can make the team as memorable for the kids that I will coach as my coaches did for me!

Ethan Loney
Assistant and Lead Coach

I graduated from DeForest High School in 2015 and I am currently a student and Resident Assistant at Edgewood College. I study Electrical Engineering and will continue to pursue my degree at UW Platteville next school year.

My swimming career started when I was in the 6th grade beginning with DFAC and I have swam every year since until college. I joined the DeForest High School swim team my freshman year and earned a varsity letter all four years on the team. My last year of swimming as a senior, I was voted team captain. Now in college, I keep up with swimming through weekly workouts at open swim on campus. I was well versed in all four strokes when I swam competitively and my favorite events were the IM and medley relay events. My favorite stroke is backstroke and my favorite stroke to teach is breaststroke.

I have been teaching higher level swimming lessons for three years and I was the 9-10 coach for Piranhas Mini Team last season. I have a passion for teaching and I really enjoy the leadership aspects that coaching offers me. I am very excited for this coming season and can't wait to coach Piranhas!

Luke Hetue
Assistant and Lead Coach

Hey everyone, my name is Luke Hetue. I graduated in 2016 from Sun Prairie High School and now am pursuing a Biomedical Engineering degree and a Math Certificate from UW Madison.

I started competitively swimming at the age of 8 with the Sheboygan YMCA and made it to state my first season. From there on out, swimming was my sport. I moved from Sheboygan to Johnson Creek after my freshman year and enrolled at SPHS for its swim program. My first summer here I also joined the Piranhas and loved it! When I swam, my strengths were breaststroke and sprint freestyle. My accomplishments over my swim career include qualifying for 14 events over four years for WIAA state, team, meet, and pool records, All-State and All-State Honorable Mentions, Rookie of the Year, MVP, Jay Haraldson Spirit Award, and two years as a team captain. I would say my best year was my senior year. After overcoming a hospital stay at the beginning of the season I came back and won both the 50 free and 100 breast at Sectionals. I continued my momentum into the following week and got 3rd at State in the 50 free and 7th in the 100 breast.

Now that my time swimming is done I want to give back as much as I can. My coaching experience includes adaptive swim lessons through the YMCA and helping with the High School Guy?s team a bit. As a Piranhas coach, I want to not only improve swimmers? strokes but expand their confidence in and out of the water. I can?t wait to have a fun summer!
