Bio: Ryan can’t remember a time when he wasn’t comfortable splashing around in the water, spending most of his summers in any convenient lake, river, pool or pond. A native of Santa Clara, California he credits his father for his earliest interest in the underwater world. Regaling a young Ryan with tales from his time on US Navy submarines and spending Saturday afternoons re-watching “Run Silent, Run Deep” a thorough subaquatic fascination was created early. Somewhere in his early teens Ryan decided that the best way to explore the underwater realm was to build his own submarine out of a 300 gallon propane tank, an ill-fated project that met it’s untimely end when he discovered something that engulfed more of his attention…women. He consoles himself with the knowledge that through SCUBA diving he is able to dive deeper, stay longer, see more and travel further than his submarine would have. Such is life.

Having long desired to take up SCUBA but falling for the classic myths surrounding the sport (It takes too long! It costs too much!) he finally pulled the trigger in preparation for his first visit to Thailand. His first stint breathing compressed air in a swimming pool was a joy, his first dive in the temperate waters of Monterey Bay was a revelation. Eventually his day job became that thing he did to pay for dive weekends and when the action-packed roller coaster of fixing cars started to lose it’s luster he decided to set off onto something new. Preparing for a new life in Southeast Asia as a full time dive professional he became an Instructor, put his stuff in storage and moved to the small island of Koh Phi Phi, Thailand with his girlfriend Alexia

For two and a half years they worked and explored their little corner of the world, enjoying world-class diving in Thailand, Malaysia and Indonesia while meeting world-class people. Eventually though the lure of returning to the United States became undeniable and they allowed themselves to be pulled back from halfway around the globe to the Big Island of Hawai’i to accept positions at Jack’s Diving Locker.

A huge fan of underwater critters, his favorites include the famous Kona Manta Rays, his furry friends the Harbor Seals from the California coast along with all sharks, turtles and Nudibranchs. He also has a fascination for man-made objects underwater and loves diving on ship wrecks and other sunken structures.
