I have been with the Marlins since 2002, starting with the parental volunteer positions of timer, stroke judge, coach liaison to the board and board member in the 4 years prior to becoming head coach and now entering my 10th year as coach. As of 2017 I have participated in 120 summer league meets, having missed one dual meet  in the 19 years I have been involved with summer league. (15 years coaching and 4 years as a parent volunteer). This gives me the unique perspective of having observed the Marlin organization from both a volunteer and professional point of view for over a decade now. The very first thing that really stood out about this team was what I saw at the very first meet. I saw swimming with tremendous heart. Add to that the fact that Marlin parents are well known for their hard work, friendliness and organization, and you have all the ingredients a good coaching staff needs to encourage athletes to become winners. And we have a very good (loyal, dedicated and cohesive) coaching staff. 

So as we move the bar of excellence higher each year, I am humbled and truly blessed to have the opportunity to work with such an outstanding organization. I pray that I can continue the cycle of returning to this community the many blessings I have received turning people into swimmers, swimmers into winners and winners into champions each summer. :-)

Nate Cox - Head Coach

Nate Cox

I’m currently a senior at the University of Texas majoring in Chemistry and simultaneously pursuing teaching certification for composite sciences at the primary and secondary levels. I’m a USA swimming certified coach, and I’ve worked with Coach Chris and the Sailfish for five years; with the St. Dominic Savio Catholic High School team for two years. I hold lifeguard and lifeguard instructor certification through the American Red Cross. This year marks my seventh year as a coach for the Marlins and I couldn’t be more excited to return. I began swimming with the Marlins 6 years prior to coaching and every year has been both fun and rewarding. As a swimmer for the Marlins, I was able to find my love for the sport. As a coach I hope to instill that same love in each and every swimmer that passes through, whether they stay for a year or a decade.


Brianna Zawadzki - This is my 12th year with the Marlins and my 3rd as a coach. I am super excited to be back with the Marlins after taking a year off to do research at the Harvard-Smithsonian Center for Astrophysics. The Brushy Creek Marlins was my first swim team, and I was also a member of the Sailfish Swim Team when it was first founded! I swam for 4 years at Round Rock High School and 4 years at Lycoming College (NCAA Division 3).This year I finished my competitive swimming career and graduated from Lycoming College where I earned a B.S. in physics with minors in astronomy and math. In the fall I will be enrolling at Penn State University to begin working towards my PhD in astronomy. I hope to continue swimming for the rest of my life as I truly believe it is the most fun and challenging full-body workout you could choose! I am passionate about helping others find joy in the sport and learn to push themselves to be the best swimmers they can be.

Alec Hudson - Coach Alec has been around the water from a young age, starting with summer league swimming in 2004. He has continued his swimming career throughout high school both as team captain at St. Dominic Savio and as a swimmer on several club teams including the Sailfish. His love for the team started when he met Coach Chris his freshman year of high school, where he experienced the special camaraderie between both the coaches and swimmers that makes it easy to love swimming. Now that he is a Coach, Alec is excited to share his knowledge of swimming and enjoys helping his swimmers reach their full potential. He aims to create a fun and encouraging environment to help swimmers achieve their goals while growing a lifelong love for the sport.

Megan Barker - The Marlins Swim Team has been a part of my life for nine years now, with 2018 being my third year coaching. After joining the Marlins when I was nine, I swam with the Sailfish year round team. During high school I swam for the Cedar Ridge High School team and played for the CRHS water polo team all four years, serving as a swim captain senior year year. I am currently a freshman in college. I plan to study either molecular biology or nutrition in the fall with the intent of attending medical school one day to become a Doctor Without Borders. What I loved most about my swimming career with the Marlins and Sailfish was the emphasis on succeeding as a team, and not just as an individual. This team spirit led me to volunteer with the younger practices and discover the joy of coaching. I owe my biggest accomplishments to the lessons I learned from my swim coaches, and I hope to be this same positive influence for future Marlins. I am thrilled to be back this season, and can't wait to lead more kids to love this lifetime sport!

 Natalie Reysa - This will be my first summer coaching Marlins and I couldn’t be more excited! I started swimming back when I was 7 years old and haven’t stopped since! I swam on the Marlins for 3 years and then was a volunteer coach last summer. I also swam for Sailfish and St. Dominic Savio all 4 years of high school. I currently swim for the club team at the University of Notre Dame, where I am pursuing majors in Political Science and Spanish and a minor in International Development. Swimming has been and continues to be a huge part of my life, both as a sport that I love and as a teacher of hard work, character, and many other life lessons. Marlins is truly a team like no other, and as a coach, I hope to continue that spirit and pass on some of the important life lessons I learned through swimming. My goal is to help swimmers truly enjoy the sport and all that comes with it, as part of the fun loving family that Marlins is! 

Intern: Carrie McKie - This will be my first year coaching for the Marlins and I am thrilled to be a part of this unique family! I started to swim seven years ago and sadly had to stop this past year after three knee surgeries, however, I found my passion of coaching when I started to volunteer five years ago. I swam for my high school team for two years, for the Sailfish swim team for five years, and for the Marlins for five fantastic years. I am so excited to have this new perspective of the sport I love so much. I am graduating from Vista Ridge High School in June and could not be more excited to attend Baylor University in the fall (Sic ‘Em!) majoring in Biochemistry and Neuroscience in hopes of becoming a pediatric neurologist. I cannot wait to pass on the love that I have for this sport this summer, and am looking forward to seeing all of the returning swimmers and to meeting our new Marlins!
