The NAU "Promise of Integrity"

Our organization guarantees that the quality of our program and tournaments are consistent and fair with respect to team play and payment of fees.

Welcome to the National Athletic Union

We are the National Athletic Union!  We are a Multi-Sport Organization specializing in providing highly organized and professionally produced tournaments/events while delivering exceptional communication to coaches, players, and parents.

Every NAU event is unique.  We think outside the box to bring you more value for your hard earned dollars and your valuable time.  At an NAU event, we offer informational clinics, fun events, team contests and prizes/awards that teams can actually use. This helps to make the competition itself something more.  For us, it’s not just another tournament, it’s a “Sporting Event” that all can enjoy!

Our passion is to provide a positive learning experience while playing the games of baseball, softball, volleyball and lacrosse while creating memories the entire family can take with them for a lifetime.

“Like” us on Facebook and “Follow” us on Twitter.

The NAU.  Quality Umpiring.  Quality Facilities.  Quality Competition.
