HOW WE TEACH

A language is something you use.

Our communicative approach connects understanding with practice. Grammar, vocabulary, listening, reading, and conversation work together, so you can make sense of the language and use it.

Lessons are taught in Spanish, with explanations, examples, and context suited to your level. You have room to ask questions, work through an idea, and try again.

HOW YOU LEARN

Structure with a person behind it.

An appropriate starting point

Written placement and oral verification help us understand your Spanish before immersion classes begin.

Teachers who guide you

Our native Spanish-speaking instructors have university training and experience supporting learners at different levels.

A clear direction

A CEFR-informed curriculum gives learning a framework while your needs and interests help shape the work.

A small school. A wider experience.

Our campus is in Playa Guiones, Nosara. Small-group immersion classes typically have 2–4 students. We recommend the 20-hour group program for sustained practice and fluency development; private instruction offers individual focus.

Beyond class, a conversation or an everyday errand gives you a chance to use what you’re learning. You can choose optional accommodation and explore Spanish with surf or yoga.
