Along with Lars, Casey is the co-founder of Imagine Swimming. He is a 1996 Canadian Olympian and was a nine-time All-American at the University of Southern California and Southern Methodist University. His competitive swimming career was centered around two of the top programs in America: the North Baltimore Aquatic Club (NBAC) and the Bolles School, in Jacksonville, Florida. Casey learned to swim when he was four years old on Dorval Island, just outside of Montreal. His daughter Eva learned to swim in the slightly warmer waters of our Tribeca Flagship.

Also a writer, Casey won three Emmys and a Peabody award for his work with NBC Olympics on the 2000, 2004, 2006, and 2008 Olympic Games. As a novelist, he is the author of the Duck Darley crime fiction series, two of which were nominated for Shamus Awards by the Private Eye Writers of America.

After a 27 year "break", he returned to competitive swimming in 2025 and went on to win two world titles in the 100 & 200 meter butterfly in his age group at the 2025 World Masters Swimming Championships in Singapore.
