Lanny is the owner and lead instructor of Underworld Tulum (www.underworldtulum.com), a purpose built dive centre in the heart of Mexican cave country with bespoke accommodation for divers.  He has been diving for over 25 years and first qualified as a technical instructor in 2005. He specialises in cave, technical and rebreather training in the beautiful Mexican caves, and is also the founder of Cave Camp. Lanny is part of the “CREER” line and safety committee in Mexico, a community organisation that works to promote safety, conservation and maintain hundreds of kilometres of cave line in the region. Before diving full time, he was a Commander in the Royal Navy with some interesting roles in submarines, surface ships and on land operations in Afghanistan and Iraq. He is also a member of the www.thehumandiver.com instructor team, drawing on experience from cave diving, mountaineering and some interesting military risk management and strategic planning roles. He is probably happiest when scootering on a rebreather in epic cave, and when not in the water, he can most often be found with a book in one hand and one of a growing pack of rescue dogs in the other.
