Greg McCormack is a professional naturalist, marine educator, and Divemaster with over 30 years of experience interpreting the natural world—especially the whales, dolphins, and porpoises of the Pacific. He has guided whale watching tours for nearly a decade with Monterey Bay Whale Watch and has worked in Southeast Alaska, Washington’s San Juan Islands, and now San Diego. Greg spent last season with Gastineau Guiding in Juneau, sharing the wonders of humpback whale behavior in the rich feeding grounds of the Inside Passage. His expedition work includes seasons in the Bering and Beaufort Seas, visiting Inupiat and Siberian Yupik communities on Little Diomede and St. Lawrence Island. In Russia’s Chukotka region, he engaged with Indigenous cultures whose traditions of whale hunting date back thousands of years—adding depth and cultural context to his interpretive work. As a Divemaster, Greg has led scuba expeditions across some of the most remote and biodiverse marine ecosystems on Earth. His voyages span the Line Islands of Kiribati, the Society and Cook Islands, the Tuamotus, Austral Islands, Pitcairn and Easter Island, as well as extensive travel through Indonesia, Micronesia, and Melanesia—from Vanuatu to Palau, Borneo to Raja Ampat, Papua New Guinea. He’s guided divers over coral reefs, atolls, and sea mounts, interpreting marine life across the Pacific’s “Coral Triangle” and beyond. Greg’s broader career includes roles with NOAA, the National Park Service, California State Parks, Natural Habitat Adventures, and Audubon. He’s worked as a ranger, kayak and river guide, expedition leader, and trainer for marine protected area staff throughout Latin America. A proficient Spanish speaker and accomplished endurance cyclist, Greg once biked over 18,500 miles from Alaska to Argentina. He just returned from cycling 2000 miles across Japan in April. He is passionate about connecting people to wild nature—whether on land or sea—and is excited to share the marine wonders of Southern California aboard San Diego Whale Watch.
