The Bainbridge Ometepe Sister Islands Association builds bridges of friendship between Bainbridge Island in Washington State and Ometepe, Nicaragua

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.

Join us on October 15th!

All are invited to a potluck and fundraiser to celebrate the connections and friendships between Bainbridge Island and Ometepe that have sustained our organization for more than 35 years. Join us for an in-person celebration at The Island School on Saturday, October 15, from 5:00 – 7:30 PM. It’s the first opportunity since 2019 to reconnect over a shared meal and hear more about the Sister Islands Association’s work throughout 2022. The event is free but registration is required so we know how many to plan for. Registration information can be found here. To see and bid on auction items, click here or on Auction in the menu for this page. If you cannot attend, you can still donate or bid on our many auction items and help us reach our ambitious goal of $30,000.

The 2021 annual meeting, via Zoom

Even though we missed the usual hugs, catching up with amigos and shared meals, the second online BOSIA Annual Meeting , on Nov. 9, was a success. We heard reports from all of the committees, including the Library Committee, Projects Committee and Scholarship Committee. Things are still a little slower than normal due to the unusual year, but we are still working to foster friendships and connections between our two islands.
