Welcome to RLS Swim Academy

Our Mission

At RLS Swim Academy (formerly ISR Sartell Swim), our mission is simple, yet incredibly meaningful: to equip children with the life-saving skills they need to be safe, confident, and capable in and around the water. Every lesson we teach is rooted in one purpose—preventing drowning, one child at a time.

Located in the heart of Sartell, Minnesota, we’re proud to serve the community we call home by providing high-quality swim instruction that goes beyond the basics. While water safety will always be our foundation, our goal is to help every child continue growing, from survival skills to confident, independent swimming and advanced stroke development.

At RLS Swim Academy, we believe swimming is more than a sport or a recreational activity, it’s an essential life skill. Through patience, encouragement, and personalized instruction, we strive to build confidence, foster resilience, and empower children to accomplish more than they ever thought possible.

As our academy continues to grow, so does our commitment to serving more families, expanding opportunities for swimmers of all ages and abilities, and creating a trusted place where children can develop skills that will benefit them for a lifetime.

Thank you for considering RLS Swim Academy to be part of your child’s swimming journey. Together, we’re building confident swimmers, stronger families, and a safer community—one child at a time.

Meet Your Instructors!

Alyssa Mohs

Founder/CEO and Certified ISR Instructor at RLS Swim Academy. As a mother of four, I know firsthand the importance of keeping children safe, especially around water. After learning that drowning is the leading cause of death in children ages 1-4, water safety & swimming skills were a priority for our family early on. However, following many years of traditional swimming lessons, I was looking for more—I wanted my children to have the skills to survive if they ever encountered water unexpectedly, to be able to find air independently, and an exit, if necessary.

Infant Swimming Resource® (ISR) is a globally recognized program that teaches infants and young children survival swimming skills. After years of patiently waiting for a Certified ISR® Instructor to offer these lessons in our area, I decided to become one myself.

In addition to being a certified ISR Instructor, I am also certified in Basic Life Support (BLS), CPR, and First Aid. I hold a Master of Healthcare Administration (MHA) degree, am a Certified Project Management Professional (PMP), and am currently pursuing my Master of Business Administration (MBA).

These qualifications, combined with my experience as both an instructor and a mother of four, deeply influence the way lessons are designed and delivered at RLS Swim Academy. It’s not only about teaching children survival swimming skills; it’s about providing a safe, nurturing, and high-quality learning environment where they can build confidence and develop life-saving abilities.

Miss Abby

Sometimes the best partnerships happen by chance! Abby and Alyssa first met while searching for a lifeguard for a child’s birthday party, and it didn’t take long to realize they shared the same vision: providing high-quality, confidence-building swim instruction that truly puts children first.

In August 2024, Abby officially joined the RLS Swim Academy team to give our students a seamless opportunity to continue their swimming journey after completing their Initial ISR program. Her dedication to each swimmer, encouraging teaching style, and passion for helping children succeed have made her an invaluable part of our academy.

Abby brings several years of swim instruction experience, having taught both private and group lessons at other local swim facilities. She is also a member of the dive team at the College of Saint Benedict, where she continues to grow her knowledge and love for aquatics and education in Occupational Therapy.

Whether she’s helping an ISR graduate gain confidence in the water or refining stroke technique with more advanced swimmers, Abby’s patience, enthusiasm, and genuine care shine through in every lesson.

We’re so grateful for everything she brings to our team and know our RLS Swim families feel the same!

Miss Heidi

Heidi and Alyssa have shared a friendship for many years. Their families have grown up together, with all four of their children born within months of one another and attending the same childcare center for over 10 years. Their shared passion for raising confident, capable kids eventually brought them together in an even bigger way.

Alyssa had the privilege of teaching three of Heidi’s children through ISR. After completing their ISR program, Heidi wanted them to continue building on those life-saving skills. She quickly realized that many traditional swim programs weren’t focused on advancing the confidence, independence, and technical skills she was looking for.

When she learned about the growth of RLS Swim Academy and the opportunity to help build a program that aligned with those values, she didn’t hesitate. She jumped in to join!

In January 2025, Miss Heidi officially joined the RLS Swim Academy team, and she has been making an incredible impact ever since. Her passion for helping children succeed, combined with her ability to challenge and encourage swimmers at the right pace, has helped many of our students’ progress beyond basic swim lessons. Several of her swimmers have advanced to the point of testing out of our program and even ready to move on to competitive swimming. We are incredibly grateful for her dedication, enthusiasm, and the positive influence she has on every family she works with!

Our Approach

At RLS Swim Academy, we focus on survival first. From day one, each child receives one-on-one instruction designed to help them adapt safely & confidently to different encountered water scenarios. Our lessons are short, ensuring every minute is used effectively and providing children with focused, personalized time in the pool.

Our Commitment

Because Sartell is my hometown, I’m dedicated to nurturing a supportive, educational space where every family feels welcome. By fostering this sense of community, we create a place where children learn to swim and develop respect for water and an understanding of its potential dangers.

Swim Education Philosophy

We offer a variety of courses, guiding children from their first splashes to advanced swimming skills. Swimming is more than an activity—it’s a crucial survival tool. Investing in your child’s ability to navigate water safely, find air, and locate an exit is priceless. Our specialized, focused lessons build the foundation for a lifetime of water safety and enjoyment.

RLS Swim Academy Reviews

After moving from out of state to Minnesota, I searched for a new ISR® instructor. My oldest son had completed the initial and refresher lessons before our move, and I was looking to continue lessons for him and start lessons for my younger son. I found Alyssa on the ISR® website and am so happy I did! I HIGHLY recommend RLS Swim Academy to anyone with littles. Alyssa is a great instructor and is so great with my boys! The skills and confidence they have learned throughout their lessons go unmatched and are why we travel 60 miles round-trip for lessons.

Outstanding attention to child safety and comprehension. Alyssa goes ABOVE and beyond expectations to ensure all her students learn life-saving water skills. HIGHLY RECOMMEND!

By far, it’s the best swimming program! I’m so glad we decided to get all three of our kids in this. Unmatched safety, and Alyssa is the best to work with! Thanks for bringing this to our community!!!

I can’t recommend ISR® enough! Alyssa is the BEST instructor! It took my daughter a while to gain confidence in the water, and she is still unsure at times, but Alyssa is excellent at making her feel safe and confident. Now, whenever we ask her if she wants to see Ms. Alyssa and go swimming, she has the biggest smile and gets so excited! It’s so fun watching her progress over the years and continue to gain confidence. This is such a great program that teaches them real-life survival skills, which is SO important.

Hands down the best experience! What a fantastic way to make your child feel safe and confident in the water! Alyssa is a fabulous instructor who has incredible knowledge and patience! If you have considered doing these lessons for your children, this is your time to sign them up!

It was the best experience that I could have ever hoped for! Our son (5) was very resistant to this, so I asked Alyssa if I should bring him back. She was so amazing at helping him through it all and easing my mind at the same time. I am so glad we pushed through because it taught him so much more! He was full of confidence (He told me, “Mom, I am really proud of myself!”). It also taught him how to overcome his fears and that he can do hard things. Of course, we are pumped about him being able to swim too. Thank you so much for giving us this amazing experience!!!

I cannot say enough good things about Alyssa and RLS Swim Academy! We brought our first son to swim lessons somewhere else when he was younger, and he learned absolutely nothing. This is not the case with RLS Swim Academy. Thanks to Alyssa, I am confident that if my child ever falls into the water, they will know exactly how to stay safe. My oldest son is now an excellent water bug, and I no longer have to fear. We have brought our youngest two kids because we’ve had such an amazing experience. 10/10 highly recommend!

I had wanted to put my kids in ISR® lessons for some time. I was so excited when I saw a new ISR® instructor closer to where we were moving. Alyssa is the best and made my daughter feel at ease. She’s learned so much from her; Alyssa has become like family!

Alyssa is truly amazing at what she does. Our 1.5 and 5-year-old were both very reluctant, and she was encouraging, patient, and knowledgeable. She continued to support and uplift them both in their journey. Above that, she’s a genuine, sweet person who makes the entire experience amazing. We’re so happy that our two small children have progressed so far in such a short time, and as a parent, knowing your kids have those skills is truly invaluable. 100000% recommend!

Growing up, I recall swimming classes mostly focusing on different ways to swim (front-stroke, backstroke, etc) more than focusing on how to save yourself if put in the situation. RLS Swim Academy is building life lessons for our little fish, Jackson. Not only is he learning life-saving skills, he is also learning how to swim safely.

I highly recommend RLS Swim Academy to anyone who is considering. Alyssa is amazing and so patient with my 18-month-old. He continues to grow his confidence with each lesson. He can get into a proper float from any situation and hold a float for 60 seconds! I am so impressed with the skills he has developed since his first lesson and his respect for the water.

RLS Swim Academy has been a game changer for my kids, ages 2, 4.5, and 7! Before starting with Alyssa, my 2- and 4-year-olds didn’t know how to float or any basic skills. Now, both can get in and float perfectly from almost any situation and jump off the side of the pool safely on their own. My 7-year-old has always been scared of trusting herself in the water, even after a few years of traditional swimming lessons. After just a few lessons, she had more confidence and skills! She’s now comfortable and confident in the water. I can’t say enough good things about the lessons and Alyssa. I highly recommend RLS Swim Academy to anyone considering it and speak highly of it to friends and family.

Putting my children through RLS Swim Academy was one of the best decisions I’ve ever made. My 3-year-old daughter, who had no swimming skills, now has the confidence and life-saving skills she needs to stay safe in and around water. Ms. Alyssa has a gift, and we loved ISR® with her. We would highly recommend it!

Alyssa was an amazing ISR® instructor for our 2.5-year-old. His confidence and excitement to get in the water has really grown through the experience, and we feel such relief that he has life-saving skills now! 10/10 recommend!
