Calphin's Program
Calphin swim programs consist of ongoing swim lessons built on our distinctive Mastery-Based curriculum. Our featured Learn-to-Swim classes for beginners offer safer small groups with structured instruction in an indoor heated pool. For intermediate and advanced swimmers, our Stroke Refinement classes stand out with professional coaches focused on stroke techniques in a 25‑yard indoor pool. We welcome swimmers ages 3 and up, from starter to advanced levels. Classes are thoughtfully organized with ratios and durations designed to match each student’s attention span and endurance.
🌊 The Calphin Continuum
Calphin now runs on the Calphin Continuum — a seamless, year‑round enrollment system designed to keep swimmers progressing without interruption.
• Consistent progress: Swimmers advance as soon as they are ready, not when a session ends.
• Flexible scheduling: Choose one or more lessons per week, with classes available 7 days a week.
• Family convenience: No more re‑enrollment hassles — tuition is billed monthly, and your swimmer’s spot is reserved continuously.
📅 Launch Timeline
• Calphin Dublin: The Continuum begins January 2026.
• Calphin Fremont: The Continuum begins April 2026. Until then, classes run section‑based at rental pools.
Families at both locations will transition from seasonal sessions to the Continuum, ensuring smoother scheduling and uninterrupted growth.
