Why Members Make A Difference

An independent and beloved Oregon nonprofit for 75 years, OMSI is dedicated to providing inclusive science exploration for communities across the region. However, we do not receive state or federal funds for operating expenses. We rely on memberships, earned revenue, and contributions to provide a financial base for engaging science learning.

What Your Membership Will Do

The financial support of a membership is more important than you realize. As soon as you become an OMSI member, you start supporting your community. While you’re enjoying your member benefits such as discounts on special exhibits, events, submarine tours, and more, you're also making it possible for OMSI to share the wonders of science with people across the region and supporting your entire community through accessible science education.

Members play an essential role in this important work, and we need your support now.
