National Umpires Association is one of the largest amateur umpire associations in the country. It is based in Atlanta, Georgia but our membership consists of numerous college and high school umpires from all over the country. Places like Georgia, Texas, Florida, Kansas, Missouri, Tennessee, California, Michigan, Ohio, North & South Carolina, Louisiana, Kentucky, Canada, West Virginia, Washington, Massachusetts and Oregon just to name a few. We work National Tournaments such as the CABA World Series, USSSA Super NIT and the Triple Crown Series as well as local youth programs.
