About ACS-OC

The world’s first whale conservation organization dedicated to bringing education, current research, and critical conservation issues to Orange County and beyond.

Leading whale conservation for 50 years.

Who we are.

The American Cetacean Society is 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 was formed in 1977 by Peter Bryant, Mike Hickey, Dave Beeninga, Dennis Kelly, Barbara Britten, Ganell Baker and others. We have members from all backgrounds, from scientists and educators to people who just love whales!

ACS-OC is a 501(c)(3) nonprofit corporation, and 100% volunteer.
