David Lim, more commonly known as ‘Yellowfish’ has been a swim coach since 1993. He began with children’s classes, and began to coach adults in 2005. He started his first adult’s swim class with just 6 students!

His students come from a variety of backgrounds ranging from complete beginners to seasoned triathletes. A large number of his adult beginners class swimmers eventually go on to complete half-ironman and ironman distance races.

David’s focus since 2013 has shifted towards coaching children.
