Our formula is proven. The GSLAU has placed more members in professional baseball than any other association, including many currently in the minor leagues or the independent Frontier League.

For high school baseball and softball, we are the exclusive provider of umpires for all of the St. Louis suburban conferences, four of the five Metro Catholic schools, all of the Gateway Athletics Conference and the AAA Conference, among others. Our umpires work almost 10,000 spring and summer high school games, plus about 5,000 summer contests. We always are looking for new members.
