Specialties
Big Blue Swim School’s mission is to show kids they can do anything by unlocking their full potential in the water. We teach year-round weekly swim lessons to kids ages 3 months to 12 years old. With no contracts or registration fees, families can start and stop swim lessons at any time. Our swim instructors teach full-time, giving kids the consistency needed to build trust with their teacher! Our flexible schedule, 90-degree water, ultra-clean pools, and spacious viewing area make for a stress-free, family-friendly experience. Parents can track swim progress in the Parent Portal. Whether you are looking for safety around water, an after-school activity, or swim team prep, our program is the ideal learn-to-swim experience for every child.
When you walk into our swim school, you’ll notice that our facility is spacious and family-friendly, offering multiple changing rooms and showers so you never have to wait. The pool viewing area is equipped with Wi-Fi and comfortable chairs for parents to sit back and relax during lessons, as well as kids activities such as coloring and train stations. Our 90-degree pools make swimming lessons stress-free for kids and parents as kids learn to swim without chattering teeth. Every class has a small student-to-teacher ratio to ensure that kids get the attention they need to make fast progress in their swim skills.
