Robert Johnson

Instructor – Revo, Optima and Mixed Gas, Repair Technician, Dive Rite O2ptima, OC Trimix
CCR Trimix, CCR Cave, OC Trimix

Robert always felt a kinship to the ocean. Intrigued with rebreathers, Robert created his own, which continues to be a work in progress. He’s enamored with the deep sea, diving, and exploration of the underworld. Robert is grateful for the opportunity to teach others how to dive safely.


Joe Citelli

Instructor – Megalodon, Pathfinder, Hollis Prism
CCR Trimix, CCR Cave

Joe has an addiction to remote location, deepwater shipwreck and cave exploration, a habit made possible with rebreather technology. Joe helped establish the current standards and procedures for rebreather diving in use today. Joe’s commitment to teaching is born out of his enthusiasm for the sport. By the way, he is also a great storyteller!



KISS CCR/SCR Instructor

Doug’s passion for diving began in 1974. After teaching recreational diving for a few years, his addiction got the best of him. He became a technical diving and rebreather diving instructor in 2005. As a cardiologist, he has a special interest in diving with coronary artery disease. Doug lectures around the world on various topics in diving medicine and is a cardiology consultant to Divers Alert Network (DAN).


As the Add Helium dive team began to explore deeper and further, they were not satisfied with the “status quo” of information. Training agencies and industry experts clearly disseminated outdated and unsubstantiated information.

We all need information based on valid research to achieve optimal dives.

The information you seek, the information we all seek, is here on our site – take a peek and improve your dives.

Coming Full Circle: Diving the O2ptima…again.

Jun 15th, 2015 by admin in Business ,Rebreather Diving

By October of 2007, I had become an Optima diver. Trading in my doubles for a rebreather was a careful decision; one involving research and asking questions. I certainly did not want to buy a “garage made” rebreather and Dive Rite, a major manufacturer of technical diving equipment, was presenting a “factory made” rebreather. Eventually,,
