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 2019 I have participated in 134 summer league meets, having missed one dual meet  in the 19 years I have been involved with summer league. (14 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

Coach Nate has been a part of the Marlins family since 2006, when he first joined the team as a swimmer. On the Marlins, he discovered a lifelong passion for the sport and went on to pursue a career as a USA Swimming Club Coach.

Nate brings over ten years of experience in swim instruction and competitive swim coaching, with students at every age and level. He is a lifelong athlete who strives to seek out new ways of understanding human kinesthetics. His multidisciplinary approach has involved a long journey of study - One that has ranged from courses on biology, education, adolescent development and psychology at the University of Texas at Austin, to forays into running, cycling and triathlon. Last year, he earned his RYT-200 yoga instructor certification and has recently been working with his athletes to improve their mobility, resilience and explosiveness through tailored dry-land programming.

It is his hope that every single child that passes through the Marlins, whether they stay for a year or a decade, can discover that same passion that gripped him in his youth. A passion for swimming, for unyielding self-improvement, and for lifelong fitness.

This will be Coach Nate's 10th year coaching for the Marlins.


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.

Coach Jacob swam for over 13 years on both Summer League and Club teams. His passion for swimming flourished when he joined Sailfish in 2013, where he connected with the swimmers, coaches, and team philosophy. Throughout the years, he was a two-time recipient of the Marlin of the Year. Coach Jacob was the team captain of the St. Dominic Savio men's team the year they won the state championship. Coach Jacob values the experience he learned from swimming and hopes that as a Coach, he can guide swimmers to enjoy swimming as much as he did.

Coach Jacob currently attends Austin Community College where he plans on obtaining a degree in the Health Sciences.

Carrie McKie - This will be my 8th year with the marlins and 3rd year coaching. I am thrilled to be returning this year! My passion for coaching began when I would volunteer in between practices when I was a swimmer for the marlins. I swam competitively for my high school team for two years, the sailfish swim team for five years, and the marlins for five years. I cannot wait to continue to pass on the love that I have for this sport. I will be a junior at Baylor University (Sic ‘Em Bears!!) and am planning on graduating this next spring as I pursue my master’s degree in speech pathology. I look forward to seeing our returning swimmers and some new faces as well!
