ISSO offers clinics, year-end awards (including youth and non-competitive activity awards), online forums, Aside World quarterly magazine, to help you stay current with side saddle news, upcoming events, informative articles and show regulations.

We have started an Aside Mileage Challenge (that recognizes the many miles ridden aside on the trails and elsewhere inside or outside the arena) with awards at 25, 50, 100, and 250 miles (whichever is the highest).

Our members ride all disciplines from Grand Prix dressage to recreational trail rides. ISSO also operates The Side Saddlery, a shop devoted to filling all your side saddle needs! The Side Saddlery offers occasional special discounts and sales exclusively to members.

As a NON-PROFIT 501(c)(3) organization, ISSO’s mission is to educate about side saddle riding. Our audience includes riders, breed organizations, youth groups, authors, historians, and people from all walks of life. Your membership directly connects you with other aside riders, while helping ISSO spread the joy of sidesaddle. Members have a say in the running of the organization through voting rights and participation in the Annual Gathering. (Memberships expire December 31.

New members joining after October 1 are automatically extended through the end of the following year.)

Best of all, our members have found many new friends with a common interest. Your membership dollars, like your donations, allow ISSO to continue providing quality educational materials about riding aside through Aside World, expos, this website, and other venues. YOU help us fill the void!
