Hi Everyone,
My name is Tom Arredondo, but during the summer I go by my alias which is Coach Tom. I am excited to be back for year twenty-three as head coach of the Round Rock Dolphins. I have been here a while now and have been fortunate to have seen thousands of kids go through the Dolphins program. What I really enjoy about Dolphins is seeing the progress that our swimmers make during the summer and from year to year. Swimming has always been a huge part of my life and I hope that through the Dolphins we will help create a lifelong love of swimming for others.
I am originally from Southern California, but have lived in Texas since 1994 so I consider myself an honorary Texan. I graduated from UT Austin with a Bachelor's in History and a Master's in American History from Pace University. In addition to my summer league gig, I also coach the RRHS Swim and Water Polo Teams. Many of our Dolphins go on to swim in high school so it is pretty amazing to be able to watch them grow up over the years.
My wife and I have three children (all Dolphins) and we live in Round Rock. In my free time I enjoy reading, Longhorn sports, camping, watching movies, fishing, and just relaxing. My favorite creatures are buffalo, whales, wolves and elk and my favorite foods are pizza, tacos and pie.
I'm looking forward to another great summer! Don't forget your sunscreen and stay hydrated!
Hip Zoo Rah Zoo Dolphins!
Hey Dolphins!! I’m Coach Adi! I can’t wait to see everyone again and meet all the newcomers! The Round Rock Dolphins have a special place in my heart because I started my swimming career as a Dolphin when I was 12 and have loved swimming ever since! After my first season as a Dolphin, I joined club swimming and later swam for Round Rock HS. I’m currently finishing up my Bachelor’s degree in Biology at Southwestern University where I’ve been able to swim and pursue a pre-med track for pediatrics. I also lifeguard and instruct swim lessons at the local YMCA and love teaching kids more about swimming as both a safety skill and sport. Some of my favorite things to do other than swim are spending time with my family and friends, kayaking, hiking, playing with my dog Bentley, and playing my violin! As a coach, I want to give kids the direction they need to improve their speed and technique while ultimately creating a fun environment for them to really love swimming and believe in themselves. I’m so excited for this season, it’s going to be so much fun! Let’s go Dolphins!!
Howdy Dolphins! I am Coach Courtney and I am so excited to be back this year coaching the amazing Round Rock Dolphins! You can find me in the south pool with all the 6 and unders this summer! I started swimming on Dolphins when I was nine (or a long, long, long time ago according to my girls) and both my girls are Dolphins! I had the privilege of coaching the Dolphins when I was in college and I was so happy to return last year! I love coaching Dolphins, seeing all the kids have so much fun, creating great memories and improving each week! I also really love working with the youngest swimmers, watching them blossom over the summer and seeing their confidence in the pool grow. I grew up here in Round Rock and graduated from Texas A&M University. My husband and I have two daughters, Izzy and Emmy. I am an elementary school teacher with RRISD. In my free time, I love to cook, spend time with my family, spend time outside, travel, and play games. I am so excited for this season and all the fun our team is going to have! Go Dolphins!
Hi everyone! My name is Coach Marko and I am excited to be coaching the Round Rock Dolphins this year. I started swimming when I was 7 years old and swam until my sophomore year of college. I swam for Round Rock Dolphins, Round Rock High School, Aquatex, and University of Texas. I am currently studying Mathematics with a Computer Science minor at the University of Texas. My hobbies include playing video games and hanging out with my friends. My favorite memories of Dolphins are the meets, pancake practice, and midsummer night scream. I look forward to a fun season and making lots of memories with you. Go Dolphins!!
Hi everyone! I'm Maggie and I'm SO excited to be back this year to coach Dolphins and see everyone back at the pool! I've coached the past 2 years and I've been swimming since before I could walk, well since I was 4, and on the Round Rock Dolphins since then as well. I'm a 4-year member of the Round Rock High School swim team and currently nanny and babysit several times a week. In my spare time, I enjoy being outdoors, reading, baking, going to coffee shops, traveling, and hanging out with friends. Next year I will be attending the University of Texas at Austin 
and majoring in either education or Environmental Sciences! One of my favorite things about Dolphins is when a swimmer goes a best time or wins their heat and gets a ribbon after their race. It's such a joyous moment to see, especially after all the hard work and training during practice. I hope to make a positive impact on all kids who pass through the program, Dolphins is such a great way to meet new people and have fun during the summer outside in the sun! I'm so excited to meet everyone and make so many new memories this season, Go Dolphins!!!!!
Hi everyone! I'm Coach Leah and I've been swimming summer league since I was 6 years old and I joined Dolphins in 2016. I've also competitively swam with Aquatex club team and the Round Rock High School swim team. As a graduating senior, I'm saddened to leave the sport that's given me some of my favorite memories and friendships, but I'm super excited to have the opportunity to give back to one of the teams that's given me so much! This fall, I plan on studying Fashion Design & Merchandising at Drexel University in Philadelphia. In my spare time, I love going shopping, sewing, playing the piano, hanging out with my cat, and of course swimming. I hope I'm able to cultivate the same fun swim environment I've grown up loving and I can't wait to meet and work with everyone this summer! Go Dolphins!
