What is ISR?
Infant Swimming Resource (ISR) is the global leader in survival swimming instruction, teaching life-saving self-rescue skills to children 6 months to 6 years old. With over 55 years of research and development and the industry's highest safety standards, we've delivered more than 19 million lessons, helping children build both safety skills and confidence in the water.
Our mission is clear: "Not One More Child Drowns." While we strongly advocate for pool fences, alarms, and active adult supervision, we recognize that these traditional safety measures aren't enough on their own. ISR's innovative approach puts children at the center of drowning prevention. With over 450,000 graduates and hundreds of documented survival stories, we've proven that children can learn to save themselves.
Our method works because we understand that children are naturally curious and capable. Rather than rely solely on barriers, we equip them with the skills they need if they ever find themselves in water alone. We transform that natural curiosity into life-saving capability, creating confident swimmers and peace of mind for parents.
In 2024, Texas lost 103 precious children to drowning, with most incidents occurring in home pools—a heartbreaking reminder of the critical need for water safety education.

Meet Your Instructor
As a lifelong swimmer and certified swim instructor, I've made it my mission to share the transformative power of water safety and aquatic confidence with both children and adults. My journey began with competitive swimming in my youth and evolved through Masters swimming, Ironman triathlons, and open water racing—experiences that have shaped my comprehensive understanding of aquatic skills at every level.
My passion for teaching swimming is rooted in two fundamental beliefs: safety and joy. As a mother of two water-loving daughters who benefited from ISR (Infant Swimming Resource) lessons, I understand firsthand the peace of mind that comes from knowing your children are water-safe. This personal experience drives my commitment to providing families with the same confidence and security through expert swim instruction.
I bring a unique blend of competitive experience and nurturing guidance to my teaching approach. My goal is not just to teach swimming techniques, but to foster a lasting love for the water while ensuring every student masters essential safety skills. Whether working with nervous beginners or aspiring competitive swimmers, I tailor my instruction to help each person reach their full potential in the water.
When I'm not in the pool, you'll find me pursuing other athletic passions—cycling, practicing Jiu Jitsu, or enjoying active family time with my two daughters and our energetic golden doodles.
