Big Blue Swim School has been wonderful for our family. Their communication is always clear and timely, and the instructors do an amazing job with my daughter’s lessons. We’ve seen so much progress and confidence in her. Highly recommend!

A very frightened and worried 6 year old, makes incredible progress in 2 lessons due to the talented and compassionate staff! Kudos!

Nancy J
We love the Big Blue Swim School!! Our daughter has progressed so much since starting as a toddler to now at 5 years old. Her instructors are so patient, engaging, and make the lessons enjoyable for the kids. The entire staff is friendly and welcoming. It’s been such a wonderful experience for our whole family. I highly recommend this school.

Jamie A
Fantastic experience for our 3-year-old who is quite timid around water and 5 years old who is more confident. Already seeing emerging skills and confidence. Facility is clean, lessons are semiprivate, and we have had such a positive experience with all the staff. Well worth the money which is fair and competitive with the market! Highly recommend.
