Greg Regan
President
In 2021, Greg Regan was elected President of the Transportation Trades Department, AFL-CIO (TTD), the nation’s largest transportation labor federation.
In his current position, Greg leads and oversees TTD’s daily operation and serves as the organization’s spokesperson and chief strategist. He collaborates with TTD’s affiliated unions to fight for long-term investments in our transportation system, ensure jobs in this sector are safe and secure, and to protect and expand the rights working people have to a union voice. Under Greg’s direction, TTD works with elected leaders on both sides of the aisle and focuses on substantive, policy-driven arguments to advance core agenda items.
Prior to being elected President, Greg served as TTD’s Secretary-Treasurer and Senior Legislative Representative and oversaw TTD’s work in aviation, passenger rail, and procurement. He is a leading labor expert on issues related to aviation safety and security, and led TTD’s fight in 2015 for Amtrak reauthorization legislation that protects and promotes our national passenger rail service and its skilled workforce. In addition, he coordinates TTD’s work to reform transportation procurement policy as a board member of the Jobs to Move America Coalition. Before joining TTD, Greg spent six years working for Congresswoman Louise Slaughter (D-NY), advising her on a variety of issues, including labor, trade, defense, energy, and homeland security. For the latter three years, he served as the Congresswoman’s Chief of Staff.
Originally from Rochester, New York, Greg holds a B.A. in Public Policy from Hamilton College. He lives with his wife and dog in Washington, DC, and is an avid golfer, hockey player, canner, woodworker, and supporter of (mostly) losing sports teams.
