About Great White Shark Diving

Great White Adventures was founded back in 1998 by Lawrence Groth. Lawrence, a commercial diver and professional mariner put together a team of professional divers and began a series of expeditions to find and observe White Sharks here in California.

The team began the first of many expeditions to the Farallon Islands in August of 1998. In September 2001, Great White Adventures was the first company to begin making expeditions to Guadalupe island. Today, Isla Guadalupe is the premiere Great White Shark Diving location in the world.
