At Harriet Plummer Aquatic School (HPAS), we believe that every child deserves the chance to learn to swim in an environment rooted in patience, consistency, and care. We recognize that learning to swim is a process—one that takes time, repetition, and gentle encouragement. That’s why we’ve built a calm, nurturing space where children can grow at their own pace and feel supported every step of the way.

Our greatest joy is watching confidence bloom—especially in those magical moments when a child takes their first swim and lights up with pride.

As we look to the future, HPAS is committed to growing as a leader in children’s aquatic education. We’re expanding our specialized programs for neurodivergent swimmers, enhancing our competitive coaching tracks, and staying deeply connected to the Lamorinda community that has supported us since 1979.
