Steamfitters Local 353 began on June 10, 1911 with twenty-six members. These twenty-six members had a vision of a strong union and a better life. Steamfitters Local 353 has one of the most highly trained and productive work forces. The United Association, along with 353, is committed to training so we can stay ahead of the needs of our customers.
On September 7, 1998, Local 353 broke ground on their new, state of the art training center and office. In 2011, Local 353 celebrated their 100th anniversary, and they are still growing strong.
