Gideon Liew has been diving since 1984. He began his experience in awe of the diverse environments to be found in Southeast Asia, from pristine reefs to mysterious wrecks. In 1994 he began pursuing a career in the diving industry, working with different operators in the developing experience guiding and teaching from liveaboards and land-based centres. His desire to dive beyond the limits of recreational diving led him to seek further education, to explore new environments, especially deep wrecks in the South China Sea. The GUE approach opened up further experiences around the world.
