The American Cetacean Society was the first non-profit conservation group anywhere devoted to cetaceans - whales, dolphins and porpoises.  ACS National was founded in 1967, and the OC chapter was formed ten years later.


The Orange County Chapter's membership has more than doubled over the past three years.  We offer free monthly meetings with guest speakers, a Volunteer Naturalist program to train docents for whale-watch boats and other venues, public outreach tables at events such as the Dana Point Festival of Whales, and much, much more!  Come join us!

Become a Naturalist!

At least once a year, ACS-OC conducts training to certify Naturalists to serve the public on whale-watch boats and other venues.   It's a great way to learn more about whales and help fulfill our public-education mission.  Click below to find out more!

THIS IS ACS-Oc!

come to a meeting!

ACS-OC has monthly meetings with guest speakers from Orange County and elsewhere.  Most of the talks are about cetaceans (of course!), but now and then our members like to hear about other topics, so we try to find a good mix.  Click below to see our upcoming schedule.

LOVE WHALES?  LEARN MORE ABOUT THEM!
