Josh Thornton, co-organizer of TEKDiveUSA, has been diving for 19 years, and instructing for 14. Josh took his OC Full Cave Course in 2004 and has been completely obsessed with cave diving ever since. He has been involved in several ongoing cave exploration projects in Utah and is currently the project leader for the Main Drain diving project.

His weapon of choice is a CCR whenever practical. Given the option, he prefers to be deep inside a cave enjoying the silence of his rebreather.

Josh is passionate about all things underwater and loves to share his passion with others at home or abroad. As a CCR Adv Mixed Gas IT and CCR Cave Instructor for TDI and IANTD he spends plenty of time guiding students through new adventures. He also teaches FII Freediving courses around the world. Josh is the training director at Dive Addicts, a world renowned diving facility and training center.

Along with his sister, brother and father, Josh launched the manufacturing and distribution company, SubGravity, in 2014. SubGravity emerged out of a desire to safely explore and experience the underwater world in some of the most extreme and demanding environments imaginable.

Josh is living the dream in Draper, UT with his wife of seven years and an energetic four year old son (who plans on being the youngest cave diver ever…) and a beautiful one year old princess.
