The ISA was founded by Larry Nash with the help of his wife Connie, in 1984 in Shelbyville, Tennessee.
He managed a local team for a while and also became a director for one of Tennessee’s existing softball organizations.
That's when long time softball player, enthusiasts, sponsor and businessman Bill Ruth of Washington State University stepped in.
In 2014 Don Stratton, Hank Heffner, and Jerry Jackson became part owners of the ISA.
