IANTD Is the world's largest SCUBA diving training organization of Open Water, Nitrox, Enriched Air, Overhead Environment, Cave, Wreck, Rebreather, Trimix, Gas Blenders, Technical SCUBA Divers, Instructors and Instructor-Trainers and now Free Diving.

IANTD is the only EANx (Enriched Air Nitrox) agency that offers training in all aspects of EANx through continuing education programs. This allows you to expand your knowledge and training with top professionals in the field. IANTD instructors are well trained, highly experienced and extremely qualified. IANTD Standards and Procedures provide for the highest level of EANx education and training available. IANTD (IAND, Inc.) was founded by Dick Rutkowski, the former dive supervisor for the National Oceanic and Atmospheric Administration (NOAA). Mr. Rutkowski introduced the recreational diving community to the technology of EANx. This program was developed through NOAA during his tenure. Today the board of directors and the membership of IANTD are composed of the most experienced divers in the world pertaining to the use of breathing alternative gases.

IANTD's mission is to understand the opportunities and challenges of Nitrox, Advanced and Technical diving, in order to foster openness, individual responsibilities, and provide a standard of care for instruction in the diving community. IANTD believes in the Golden Rule and will be honest, ethical and fair in all our venues. We also believe that there are universal principles and natural laws that are more absolute and we try to live by them.

We envision our mission activities in the following areas:

Public Awareness and Advocacy
Safer Diver Program
Program Development and Refinement
Fostering Community
