Last updated September 7, 2026

The International Association of Nitrox and Technical Divers was founded by Dick Rutkowski in 1985 as the first agency to teach nitrox diving, and expanded through the early 1990s into one of the most extensive technical training catalogs in the industry — covering trimix, cave, wreck, mine, sidemount, and closed-circuit rebreather diving across multiple depth-tiered levels.
