Foss Swim School is a regional swim-lesson chain with a Sun Prairie location offering year-round swim lessons for children in small classes (3-4 students per teacher) grouped by age and ability, plus private and semi-private lessons. Founded in 1993, it is a year-round swim school rather than a summer camp.

★★★★★Steph KosmauleLove Foss, been swimming with them since the kids were 6 months. The staff is warm and inclusive, and so is the pool!
★★★★★Rhoda McKinneyWonderful caring staff and swim instructors. They are awesome at adapting to your child's age and abilities. I would highly recommend no matter what your child's age is, my grandson is 8 months and started lessons at the minimum acceptance age of 6 months. I bought him swim lessons for his first Christmas. Best gift ever!
★★Kate FHave two kids who have attended over a year. Was very satisfied in beginning but not anymore. Parking lot is too small, not enough changing rooms because they have started to have too many classes at same time. Kids haven't progressed as I feel they should for over a year of classes and a few thousand dollars spent. Not worth the drive and hassle finding parking and having car damaged in parking lot.
★★★★★Kyle MeiseWater is comfortably warm enough for timid kids without being too warm. The instructors here are very engaging and great at helping younger kids overcome struggles and build foundational skills. The facility is on the small side and very busy so it can be crowded at times. Lanes are short so longer and more difficult strokes for experienced swimmers are hard accomplish. Facility is very clean and has all the necessary amenities. Teacher ratio is typically 4 kids to 1, but often more like 3 or 2 to 1. Highly recommend.
★★★★★Bree CostaWe have two swimmers in different levels and have worked with multiple teachers. Working with kids can be a challenge, but the teachers make sure the kids are comfortable and safe while pushing them to learn and improve. The kids are always excited about their next lesson. The facilities are clean and well maintained. I've always been a worrywart about water, and the lessons have brought me some peace of mind as well. All around, good experience!
