At the age of five, Mark began swimming in Texas to cool off from the intense 100-degree weather. When his family moved home to Calgary two years later he joined the Cascade Swim Club and launched his successful swimming career. After a few years of age group swimming with Cascade, Mark decided to move on to the University of Calgary Swim Club under the guidance of Hall of Fame coach Deryk Snelling. After 12 years of perfecting his technique and improving his conditioning, Mark made his first national team at the age of 17.
Among his swimming achievements, Mark won a total of four gold medals at the 1986 and 1990 Commonwealth Games, both at the 100-metre backstroke and 4x100m medley relay.
