USSSA governs 13 sports across the US, Puerto Rico, various US Military bases and Canada, and has a membership of over 3.7 million.

[1] USSSA was originally founded in 1968 in Petersburg, Virginia, but moved to a new headquarters in Space Coast Stadium in Viera, Florida in the spring of 2017.

The founders of the organization are Robert Mueller, James DiOrio, Ray Ernst, Frank Ciaccia, and Ted Mazza.

These developments include longer fences, 65 foot base paths, a smaller batter's box, widened media coverage, and encouraged greater financial support.

[2] Over that last weekend of August 1968, the first USSSA world softball tournament was played in West Allis, Wisconsin.

Over the past 40 years USSSA has grown from a couple of thousand slow-pitch softball players to over 3.5 million participants playing 13 primary sports.

Prior to 1975, ASA, then the largest slow-pitch softball association, barred any of its teams from playing in any non-ASA sanctioned event or league.

USSSA grew rapidly throughout the 1970s and 1980s, adding new programs such as Church, Corporate, Women's, Mixed and multi levels of Men's play, along with structured Divisions such as Central, Southern, and Midwest.

In 1980, the USSSA took a big step with their organization by birthing a Southern Division to expand the number of teams that could play.

That next year, the USSSA was able to purchase a huge 24,000-square foot complex in Petersburg, VA for its National Headquarters and the Museum for its Hall of Fame.

In 1983, the USSSA adopted a large insurance policy to protect the teams and umpires from accidents on the field at a low cost which continued to further their reputation as a good and sound baseball organization.

The year 1990 was a very momentous occasion for the USSSA as the first slo-pitch softball tour of the Soviet Union occurred, with the team traveling through and playing in Moscow, Leningrad, and Tallinn.

USSSA offers programs and tournaments in Baseball, Basketball, Fastpitch, Flag Football, Golf, Martial Arts, Lacrosse, Soccer, Slow-Pitch, and Volleyball.

Also during this year, Don DeDonatis made public the decision to move the USSSA National Headquarters and their Hall of Fame to Osceola County, Florida in 2003.

In November 2015, Don DeDonatis made public of the associations intention to move USSSA headquarters from Osceola County, FL to Viera, Florida and to also renovate the former home of the Washington Nationals at Space Coast Stadium and create the USSSA Space Coast Complex.

In 2017 with the assistance of the Brevard County Board of County Commissioners, the United States Specialty Sports Association (USSSA) moved into the empty Space Coast Stadium and the surrounding spring training fields and renamed it the USSSA Space Coast Complex, moving its headquarters from Kissimmee to Space Coast Stadium and announcing plans to renovate the entire complex, using US$22 million of its own and US$10 million contributed by Brevard County.
