While this year was a challenge in many ways, your generous support ensured that marine mammals were responded to while we continued to prioritize safety for our staff and volunteers. Thank you from our team!

Aliah Meza

Operations Manager, San Luis Obispo Operations

You enable a whole community of staff and volunteers to make a difference. We’re able to rescue and heal marine mammals while sharing our scientific knowledge with the global community. Through that, generations of people, younger and older, locally and globally, are inspired by the unique story and mission of the Center. Thank you.

Marc Lie

Animal Husbandry and Rescue Volunteer

Much has been put to the test, but thanks to this steadfast community, the Center was able to adapt, continuing its core work safely while pursuing innovative ways to connect, educate and inspire. Thank you.

Cecily Majerus, M.A.

Chair of the Board of Directors

Your support is essential for our necropsies and research, because it advances our overall understanding and allows for future inquiry. Thank you so much for your contribution and giving us the ability to further our conservation work.

Barbie Halaska

Necropsy Manager

While we were farther away from one another this past year, I’ve never felt closer to you, our supporters. Your unwavering commitment to our mission fuels us and allows us to have high impact in spite of the challenges we face.

Jeff Boehm, DVM, Dipl. ACAW

Chief Executive Officer

Your contributions supported teachers and students by providing curriculum and virtual opportunities that brought science to life, helping them become ocean stewards. During a year when schools have been so affected, the impact of these programs is even more meaningful. Thank you for helping to make this possible!
