After an 18 year professional cycling career, I started my own SCUBA dive school in 1995.
After 12 years of supervising the divers on our great white shark trips, I aquired Shark Diver. We offer shark dives all around the world.
Great White Shark diving at Isla Gadalupe, Hammerhead-, Tiger-, and Lemon-sharks in the Bahamas and Bull-sharks in Fiji
