Hidden Forest Piranhas Coaches


I was introduced to swimming at five years old at the Eldorado pool here in San Antonio. I went on to swim competitively in Colorado and Virginia (who has one of the most competitive summer swim leagues in the nation) returning to San Antonio and swimming through high school at Churchill. Swimming has always been my part-time passion. I have owned a small business that has allowed me to pursue it and went on to get my Masters in Coaching and Athletic Administration. Over the years I have been exposed to many coaches and coaching philosophies and used that experience to encourage and teach swimmers to do their best. I have coached at Shadow Cliff, Northwest Crossing, Fair Oaks Ranch and Antonian High School before coming to Hidden Forest several summers ago. I also led a summer swim league for AAAA for several years. Last season I was unable to coach, but I am back and ready to have a great season. I've coached Sharks, Dolphins and my favorite, Piranhas. Piranhas individually are small but work together to achieve great things. It's feeding time.......


Hi, my name is Marlie Riojas and I am super excited to be returning to coach this year. I am studying Christian Ministry at Regent University and work for YoungLife leading a middle school ministry called WyldLife. I was a Hidden Forest Piranha swimmer for 14 years and am returning for my 5th year as a coach. I swam on the swim team at Churchill High School for 3 years swimming various events as well as was a club swimmer for a little while. Being a Piranha for 14 years I have many memories on this team. Some of my favorite memories are from swimming in meets with friends and just having fun bonding with my team mates. Coaching the past five years has also given me some of the best memories. It is so rewarding watching the improvement of swimmers over the span of the season and seeing swimmer return the following season. I can’t wait to see the awesome things we do as a team this season and what fun memories we make! Go Piranhas!


Hi I’m Hannah Hipp and I’m so happy to be coaching this year for the Hidden Forest Piranhas! I am a junior at Antonian College Preparatory High school and I’ve swam for the Antonian team for two years now! I’ve been part of the Hidden Forest family for many years now and have loved every minute of it! I’ve met some of my best friends through the swim team and had many great adventures! Competing with the team is my favorite because you get to cheer your friends on and everyone is so encouraging! I’m so excited to see everyone again and make even more amazing memories! Let’s make some Bubbles! Go Piranhas.


Hi, I’m Ethan Moilanen and I’m excited to be coaching this year at Hidden Forest! I am a junior at Churchill High School, and I’ve swam on the varsity team for three years. I’ve swam for Alamo Area Aquatics Association for four years total, and have been a part of the summer league experience since I was five. My favorite parts about swim team are the great sense of community and the growth seen over the season. I’m excited to give back to the sport that has given so much to me. Go Piranhas!
