Your Impact as an OMSI Member

When you become an OMSI member you join a community  that is wildly curious and believes that fun, engaging science education should be available to everyone.

Our members create a ripple effect in our ability to positively affect our community. Whether it be bringing our inquiry-based science to more regions around the PNW or enabling OMSI access to more schools and families in under-served communities, your membership provides benefits far beyond your own household.

Sure, becoming an OMSI member gets you major perks: free admission to the museum, discounted tickets to featured exhibits, and insider access to special events. But members don’t just get the best of OMSI — they give the best of OMSI to others, too.  

Nonprofit Memberships

OMSI offers nonprofit memberships to social service, education, and community organizations that provide services to families or individuals.
