BECOME A MEMBER
Bring the Family
When you join or renew your annual family membership to Marine Science Institute, you become part of a community of amazing people who have a passion to engage, educate and inspire students to be stewards of the environment.
Your tax-deductible donation helps provide food for our aquarium animals, interactive trips into nature for Bay Area students and hands on experiences for those who visit our facility.
If you donate $60 or more through a third-party platform (such as through your employer) you are eligible to receive Membership benefits. Please note there is a delay between your donation date through a third-party platform and when MSI receives notice of the donation. If you have donated through a third-party platform and have not received confirmation of your donation from Marine Science Institute, please contact membership@sfbaymsi.org.
