Our History

For more than 30 years, we have constructed schools and water systems together, learned each others’ languages and customs, and been welcomed into each others’ homes.

Much has changed since 1986, when Kim Esterberg first set foot on Ometepe in search of a sister island and Moyogalpa Mayor Diego Martinez told Kim that what Ometepe needed most was respect. What has not changed is the vision of a long-term, sustainable relationship—a mutually beneficial partnership of equals. This mutuality of respect is what we hold true to as we continue on into our second quarter-century.
