Masters Swim

Who it’s for: Ages 19+

Think of Masters Swim as an organized swim team for adults. Open to the entire community, it’s a year-round, coach-led program that delivers structured workouts, stroke technique coaching, top-notch swim drills, and fast-paced speed sets in a welcoming group setting. Lanes are divided by speed so everyone swims at a pace that suits their ability and goals.

Each session is led by a dedicated coach who designs varied, challenging workouts to keep you improving. Sessions run Sunday, Tuesday, and Thursday mornings from 6–7am (with Sunday at 7–8am), plus Monday and Wednesday midday from 12–1pm, making it easy to find a schedule that fits your week.

Masters is perfect for triathletes, competitive swimmers, and anyone who simply loves a great group workout. Optional swim meets are available for those who want to compete, but there’s no obligation. Many participants come purely for the training and the tight-knit community that comes with it.

Pre-Swim Club

Who it’s for: Ages 6–10

Pre-Swim Club is the bridge between swim lessons and the Karishim Swim Team as a supportive introduction to the basics of competitive swimming without the competition. The program focuses on building proper technique across all four strokes: butterfly, backstroke, breaststroke, and freestyle, as well as fundamentals like circle swimming, using a pace clock, and understanding team etiquette.

Like Karishim, Pre-Swim Club is skill-based rather than age-based. To participate, swimmers must be able to complete a 50-yard (down and back) lap of both freestyle and backstroke. From there, the program adapts to each swimmer’s pace. When a swimmer shows readiness for the full team, they’ll be the first to know.

Pre-Swim Club is coached by Lauren Gale, Head Coach of the Karishim Swim Club, so swimmers are already building a relationship with the team they’re working toward.

Tryouts for Pre-Swim Club are happening at the Open House!

Who it’s for: All Ages and Abilities

Every swimmer deserves the chance to be in the water. Our Adaptive Swim program offers personalized, one-on-one instruction for swimmers of all ages and abilities using the Swim Angelfish® methodology and Lenny Krayzelburg Swim Academy techniques. We start with a comprehensive intake process to understand each swimmer’s individual needs, behaviors, and goals, and build customized lesson plans from there. Families, caregivers, and support professionals are actively involved throughout.

Our facility is fully equipped to support swimmers of all abilities, including a hydraulic lift for pool entry and exit, private changing rooms, and sound-dampening panels around the indoor pool to reduce noise for swimmers with sensory sensitivities.

We also offer a free Sensory Swim Hour every Saturday, which is a dedicated, low-sensory pool session for individuals with autism and other sensory needs, supported by the NLM Family Foundation in partnership with Autism Welcoming.

Adult Swim Lessons

Who it’s for: Ages 18+

It’s never too late to learn to swim, or to get better at it! Our private adult lessons offer one-on-one instruction in a supportive, non-intimidating environment, tailored to your goals whether you’re a complete beginner, building confidence after time away from the water, or training for a specific event.

All lessons use a combination of the SwimRight® method and techniques from the competitive swimming industry, and are customized to your individual ability level. Fill out a short registration form, share a little about your goals and experience, and we’ll match you with the right instructor — no pre-evaluation required!

Lessons are available Monday through Friday, 10am to 3:30pm, and can be scheduled as a single session or on a recurring basis.

Children’s Swim Lessons

Who it’s for: Ages 3 Months & Up

Swimming is one of the most important skills a child can learn, and we make sure it’s fun from the very first lesson. Our children’s swim lesson program is built on the SwimRight® method, using a swim-float-swim technique as its foundation.

The focus is on water safety and building the muscle memory that helps swimmers instinctively react safely when they enter the water, not only for passing swim tests but genuinely knowing how to approach the water safely.

Classes are available as parent-tot lessons, small group lessons, and private lessons, with certified instructors who give each child personalized attention. We also offer perpetual sign-ups, so you can join whenever it works for your family and adjust days, times, or instructors as needed.

Karishim Swim Club

Who it’s for: Ages 6–18

Karishim is JCC Greater Boston’s year-round, USA Swimming-sanctioned competitive team for swimmers ages 6 to 18. Swim groups are led by USA-certified coaches in a low coach-to-swimmer ratio setting, giving each athlete individualized attention and personalized training. Swimmers participate in a wide range of local competitive meets each season, with groups ranging from beginners finding their footing all the way to national-level competitors.

With a supportive community of athletes and a safe, friendly environment, Karishim is a place where swimmers grow, build lasting friendships, and reach their full potential in the pool.

Head Coach Lauren Gale brings competitive swimming expertise and a background in nutrition and wellness to every practice.
