REEF members are the heart of our grassroots marine conservation programs. Divers, snorkelers, and ocean enthusiasts worldwide stand behind our mission.
This month we highlight Callie Mack, who has been a REEF member since 2011. She is level 5 expert surveyor on the U.S. west coast in the PAC region, and has submitted nearly 400 surveys. Callie lives in San Diego, where she enjoys diving the nearby kelp beds and rocky reefs to search for interesting invertebrates and fish.
