Additional Info

Jon Kieren is a cave, technical, and CCR instructor/instructor trainer who has dedicated his career over the past 15 years to improving dive training. As an active TDI/IANTD/NSS-CDS and GUE Instructor, TDI Training Advisory Panel member, and former training director for TDI, he has vast experience working with divers and instructors at all levels, but his main professional focus resides in caves.

In his own personal diving, Jon’s true passions are deep extended range cave dives (the more deco the better), as well as working with photographers to bring back images of his favorite places to share with the world.
