Registration for an event is 3.5 weeks prior to that event on the Tuesday at 12pm EST. Please send entries by email to doubles@isdasquash.com. You must receive an email confirming your entry to be registered in an event. In addition, membership dues as well as player agreements must be received at the ISDA PRIOR to an entry being accepted into a player’s second event (this applies for both players). Please review on this website the section on how to become a member as well as the ISDA tour manual for further information.
