ILEA, formerly the International Special Events Society, was founded in 1987 to foster enlightened performance through education while promoting ethical conduct. ILEA works to join event and meeting professionals to focus on the "event as a whole" rather than its individual parts. ILEA has grown to involve over 5,500 members active in over 50 chapters throughout the world. The solid peer network ILEA provides helps special events professionals produce outstanding results for clients while establishing positive working relationships with other event colleagues.

The ILEA Nashville chapter formed in 2012.
