Steve Lewis has been an active technical diver, instructor and expedition leader since the early 1990s when diving was an antidote to a career in marketing and brand management. In 2002 he retired from the corporate world and became a dive bum full-time, and is currently a training, and product consultant for a major rebreather manufacturer and design consultant for a leading open-circuit dive equipment company. As a speaker, educator, and blogger, he is best known for promoting safe diving practices to technical divers using both open and closed-circuit kit, in caves, on wrecks and in open water environments.
