As with all unions, the leadership of the International Brotherhood of Boilermakers comes from its members.
Members elect local lodge officers and delegates to the Consolidated Conventions held every five years. At the convention, the member-elected delegates elect International officers. Delegates, local lodge officers, and International officers are all members of the union.
Member-elected convention delegates also vote on changes to the International’s Constitution, which governs the actions of all International officers, staff, local lodges, and members.
At every level, members lead the union.

After his military career, he took a job at a local nonunion shop, and in 2002, he saw a Boilermakers’ newspaper ad seeking welders. He answered the ad, went on a job, took a make-or-break test and never looked back.
After graduating from apprenticeship in 2006, he later served L-374 as a lodge inspector, sergeant at arms and vice president before being elected BM-ST.
“I hope to make proud the retirees and those who went before me, helped me along the way and paved the way for new leaders like me,” he says. “I will always maintain the Seabee ‘Can Do’ spirit. There’s nothing we can’t do, and that’s what I’m going to bring to the table: Don’t take ‘no’ for an answer, find a way through challenges and find a solution.”
Sulivan, who is married and the father of one boy and four girls, has also been an advocate to women in the trades and to NABTU’s Tradeswomen Build Nations program. He is Second-Vice President for the Indiana State Building Trades and is an Industrial Sector Vice President for the Northern Indiana Labor Federation, AFL-CIO.
