The Thunderbirds were founded in 1937 with the mission of promoting the Valley of the Sun through sports. The Thunderbirds consist of 55 “active” members and more than 250 “life” members. The Thunderbirds are the host organization for the Waste Management Phoenix Open, which is the best-attended golf tournament in the world and has gained legendary status for being the most unique stop on the PGA TOUR. The Waste Management Phoenix Open is often called the Greatest Show On Grass.
