Reviews
"We are very pleased with the management and swim instructors at Foss Swim School. My toddler can be a handful yet the instructor kept her focused and on task. We chose the once a week group lesson for the entire summer, but other options are available. Parents can sit and observe their swimmers right by the pool or in the large, air conditioned lobby. I enjoyed being by the pool and hearing the teacher's direction while my husband watched from the cooled area."

"Staff is very friendly and professional. At first My 20 month old did not like getting her hair wet and was unsure about water. So, we signed up for the baby swim classes and now she likes the water and will even jump to go underwater. I happy she is having a positive experience with swimming at a young age. Foss swim school has provided that."

"My daughter takes baby swim class. She is 9 months old and has learned to control her breathing when going underwater. Each week her under water skills and comfort in the water have improved. I love how professional Foss is and love their mini shop in the front in case you forget anything."
- FOSS Parent
"The experience we have here every week is amazing. This is how you train kids how to do things. Every employee seems genuinely happy to be here. The kids love coming. They have a great time and learn at the same time. We recently went to a “physical activity” type place for our next venture and we were not impressed. All future venues will be measured by this place."
