The GLOA trainers know that becoming a quality lacrosse official is not done just through classroom and field training. Self-study is a huge part of becoming a better official. This page lists every resource that the GLOA trainers, Greg Hite, Gordon Corsetti, Bill Powell, Clyde Allen, Andy Halperin, Jeremy Redmon, and Stuart Smith have created or recommended as beneficial to lacrosse officials of every experience level. If you come across something that you found helpful please let us know so that we can share it here.

Check out these pages for information on Uniforms and Equipment or to view the two man mechanics training PowerPoints on the Presentations page or the videos of these presentations on our Youtube Channel.


Important documents for U.S. Lacrosse and GLOA officials are posted here and are available for download.
