About Lessons

Infant Swimming Resource (ISR)

For children 6 months to 6 years, I initially teach water survival, as opposed to splashing and playing or technique (i.e… breaststroke, front crawl, etc.). If a child should fall into the water, she will be able to swim with her face in the water, roll over to float so she can get some air and maintain the float, if necessary, then flip back over to swim and continue that sequence so she can get to the side of the stairs to get out to safety. A child younger than around 15 mo learns to hold his breath in the water, to get to a float, and to maintain a float until someone can get to him. I can teach a child as young as 6 months as long as he can sit independently without flopping over for at least one minute.

Because young children learn through sensory-motor learning, or the muscle memory of how their bodies should move through the water, they need much repetition. Therefore, the lessons are 5 days/week, Monday-Friday. All lessons are one-on-one, so the child works very hard and may get fatigued, so the lessons are no longer than 10 minutes per day.

Children under 15 mo. usually take around 5 wks. to acquire the skills. For a child older than that, it typically takes about 7-8 wks. I don’t guarantee any time frame because each child is different, and I don’t want him to end lessons until he is safe in the water. At the end of the lessons, I will test the child’s skills with clothes on. Ninety percent of water accidents occur with clothes on, so I want to be sure he will be safe if this happens when he is fully clothed.

Stroke Development

I am also Red Cross certified and teach traditional swim lessons to children. I am happy to teach stroke development to girls aged 3 ½ years and up and boys 4 years & up who are already ISR skilled. I always start with ISR, as children should first have basic survival skills in the water, and it is an important precursor to strokes. Once ISR skilled, children are already partly through level 2 of the Red Cross program.  Students learn proper form in strokes, breath control, water safety, treading, and more through the Learn to Swim program. All lessons are private and one-on-one, resulting in quicker skill development. The price and schedule structure are the same for all types of lessons.

Swimming with Autism

I am also trained in the Swimming with Autism program. Children with autism learn the same ISR skills but with an adapted format, which makes it easier for them to learn. It often takes longer for children with autism to learn the skills, so parents’ expectations should adapt accordingly. Again, the price & schedule structure is the same for all lessons.


  • $150/week per student for both ISR and stroke development (initial 2-week deposit is non-refundable)

  • $105 registration fee/student for 1st time ISR students. This fee goes to the corporate office (non-refundable)

  • $25/student administration fee (non-refundable)

Once we settle on a time slot, I will send you the registration link and reserve it for 24 hrs or less to give you time to register and make the deposit. 

To reserve your slot, you must register online and pay the first two weeks’ tuition & admin fee (both non-refundable) upfront. The registration and the deposits are due within 24 hours of initially scheduling your slot. For the 2-week deposit & admin fee, I can take payment via Venmo or cash (which you would need to drop off to me). If you have not made the deposits and registered within that time frame, I will open up the slot to someone else. Be aware that no make-up lessons are given except for inclement weather or if I cancel, so keep that in mind when scheduling. 

When you register online, you will fill out a brief health history of your child, which goes to a medical team. They review your information and will get back to you directly with any concerns or questions. They must give me approval before I can teach your child. They will also send you a digital parent resource book and a code for $15 toward the ISR Seal Store, where you can buy things such as an ISR t-shirt or a reusable swim diaper.

If you are interested in registering, please let me know, and we will find a time slot for you. I will then send you the link to register.

A Word About Crying

Be aware that children often cry during lessons. The number of days and how vigorous the crying will be varies greatly and depends on your child’s age and personality. Often, the younger the child, the more they’ll cry. Also, some children like to be in control more than others, and they cannot be in control during lessons if they are not yet safe in the water. They are not initially comfortable in the water because they are not yet skilled.

Children cry for various reasons, but mostly because they are made to work in the water rather than play, which may make them unhappy. ISR lessons are hard work, and often young children have yet to experience pushing through a challenge to master a skill.  Also, children typically learn skills in their own time (rolling over, walking, talking, potty training, etc). Typically, ISR lessons are their first experience with having someone else set the pace of learning, which can be more challenging.

With all of that being said, the vast majority of students do calm down and typically eventually love swimming and being in the water, especially once they start mastering the skills. Once children are competent in the water, they are both comfortable and safe in the water. I have never had the parent of a student who completed lessons tell me that their child fears the water. They often can’t get their child out of the pool because they’re having so much fun.

If you decide to register for lessons, please be prepared for a bit of crying and know that the reason I teach is so your child will both love and be safe in the water. It’s better not to register for lessons than to pull them out before completing lessons because you see them cry. In this case, you are not giving them the opportunity to get through the challenge and be successful in the end, but teaching them you can quit when it becomes uncomfortable. You are potentially saving your child’s life, and a bit of crying is not going to hurt them. If your child cries because they don’t want to sit in their car seat, you will still strap them in because you are doing so for their safety. ISR lessons are the same thing!

I hope this is a fairly clear explanation of what I do. I encourage you to go to to watch videos and get more information on the technique. Also, “Like” me on Facebook at Please let me know if you have any further questions.

Thank you and I hope to see you this season!
