We are currently an entirely volunteer-run organization and thank you for your support!

The American Cetacean Society is a tax-exempt 501(c)(3) non-profit public benefit corporation, governed by a national, volunteer Board of Directors and managed from its headquarters in San Pedro, California. Because ACS is organized as a single organization rather than as separate local legal entities, ultimate fiduciary and policy oversight for the operations of the American Cetacean Society lies within the purview of its National Board of Directors.
