Once a Cavalier's marching days are done, he moves on to being a member of the Cavalier Alumni Association.

CAA is designed to encourage continuation of the fraternal aspects of being a Cavalier, and provide alumni support for the operations, aspirations, and logistical needs of The Cavaliers organization. Toward that end, the CAA has created the Backyard Brawl fundraising challenge, the GEARS program of alumni-only financial support for the corps,  the annual Family Day BBQ on Memorial Day weekend, and the Cavalier Endowment Fund, a long-term financial instrument for The Cavaliers that has already raised over $550,000 in collected and pledged endowed support for the corps. 

CAA has a standalone Board of Directors, and publishes its own online newsletter for alums-only (splooiEmail), with information for the alums that might not be available to the general public.
