Monthly Giving


Become a Monthly Donor and help animals like Hermes and Pearl 365 days of the year!

The Monthly Donor Fund helped Pearl and Hermes, two endangered Hawaiian monk seal pups that were rescued on a tiny atoll named ... Pearl and Hermes. They were found underweight and malnourished. Once they had put on a healthy amount of weight and demonstrated the ability to eat fish on their own, Pearl and Hermes were released back to their home in the Northwestern Hawaiian Islands.

A great way you can help ensure that we're always able to meet the needs of each patient is to make an automatic monthly gift. Your tax-deductible contribution may be relatively small each month, but they'll add up fast and give the Center an ongoing source of income we can depend on to perform life-saving surgeries, conduct advanced tests, and buy food, formula, antibiotics and other supplies that these marine mammals patients so desperately need for a second chance at life. 

As you might imagine, the patients at The Marine Mammal Center require care and attention seven days a week, 365 days a year. Our rescue teams and hospital must be ready at all times to respond!

People like you who care deeply about marine mammals have chosen to give through our tax-deductible Monthly Donor Fund to help provide care for the patients.

It's simple to set up right now using your credit card*

  • You maintain complete control over your giving and can change or cancel it at any time via a secure login.
  • Each February, you'll receive a year-end statement of your previous year's giving to help make tax-time a little easier.
  • Your membership is automatically renewed.
