Elena Argueta - Age Group Coach

Elena@machineaquatics.com

I was born, and currently reside in College Park, Maryland. My competitive swimming journey started in 2013 on a small summer team. I joined Machine Aquatics in 2018, and have not looked back! 

During my time as a swimmer on Machine, I became certified for lifeguarding, worked at two pools, then offered swim lessons for my local community pool. In the summer of 2023, it was offered by my mentor, Dan Haines, to become a coach! I will always be thankful for this job, because I truly love teaching aspiring swimmers. 

There is always something to learn, and there are always ways of improvement. I hope that my time at Machine Aquatics only grows my knowledge for coaching, and for life. Outside of swimming, I enjoy baking pineapple-upside cake and cookies. Roller skating is also one of my favorite hobbies! Thank you very much for reading.

Austin Rider - Age Group Coach

austin@machineaquatics.com

Hi everyone! My name is Austin Rider and I coach at the University of Maryland site. I started swimming at the age of 6 with the Kingston Chase Fighters in Herndon, VA, swimming there for 11 seasons before moving to the Four Seasons Tidal Waves (also in Herndon) for my last 2 seasons. My coaching career started as a junior coach with Kingston Chase and I really got into coaching with Four Seasons, where I worked as an assistant during my final 2 swim seasons before taking over as head coach for the next 3 years after graduating off the team.

Following my graduation from James Madison University and my final season with the Tidal Waves, I accepted a full-time role in the fall of 2019 as the primary Seniors and Gears coach with Machine at UMD and have also helped coach the Adelphi Dolphins summer team for the past five seasons. As of the 2022-23 season I moved from Gears to HPs while continuing to coach all senior groups at UMD, and I’m excited to kick off my sixth season with Machine!

Trent Badrak - Age Group Coach

trent@machineaquatics.com

Hello! My name is Trent and I am a sophomore in college studying chemical engineering at the University of Maryland. 

I started my swimming career on the Adelphi Dolphins Swim Team at seven years old. I swam for UMAC, and then later moved to Machine. I swam for Machine for around seven years before graduating and then going to college, which soon after I started coaching for Machine at the UMD site. While I was a swimmer, I made my way to some meets like NCSA’s in Orlando and Senior Zones in Pittsburgh. Many don’t know that UMD doesn’t actually have a NCAA swim team, so post-Machine, I compete on UMD’s club swim team (although I wasn’t going to do NCAA anyways). Last year, I was a captain on it for the second semester, and my job there was to write every practice for the club. 

A fun fact about me is that I love to play the electric guitar! My favorite music is hard rock and metal from the 70’s, 80’s, and 90’s, which influenced me to play the guitar. I especially love Metallica, Red Hot Chili Peppers, Dream Theater, and Alice in Chains. 

Ellie Kim - Age Group Coach

ellie@machineaquatics.com

My name is Ellie and this is my second year coaching for Machine Aquatics. I started swimming when I was 9 years old with my summer team, the Adelphi Dolphins. I joined Machine Aquatics a year later and swam with both teams throughout middle school and high school. It took up a ton of time and included a ton of early mornings, but I was always motivated to go because of my supportive coaches and teammates. One of my favorite things about coaching is teaching the 9-10s and 8 and unders. I love their enthusiasm! I'm a student at the University of Maryland majoring in Nutritional Science and Music Performance.

Matt Mueller

I'm from the DC area and started swimming competitively at eight years old. My love for the sport started with my local summer pool, but soon extended to high school and club swimming. I study mechanical engineering here at UMD and have swam on UMD Club Swim for the past three years. I'm one of the Gears Level coaches at the UMD site.

In my free time, I love to explore the outdoors. I love surfing, skiing, and doing backpacking trips with my little brother. I'm excited to see everyone in College Park!
