The International Squash Doubles Association (ISDA) is the governing body that manages and runs the World Professional Squash Doubles Tour. It features the top ranked male squash players in the world and is hosted by the most prestigious clubs in North America with over 20 professional  events each year.

Graymatter has worked closely with the ISDA since 2007, designing the current website (complete with a comprehensive content management system), a bi-annual magazine, posters, event pamphlets, and business cards etc.

Together we have transformed the image of the tour into a polished and organized outfit that continues to grow and attract some of the most talented teams from around the world.
