Lori Trahan

Lori Ann Trahan (/trəˈhæn/ trə-HANN; née Loureiro; born October 27, 1973) is an American businesswoman and politician serving as the U.S. representative for Massachusetts's 3rd congressional district since 2019. The district covers Boston's northwestern suburbs, and includes Lowell, Lawrence, Concord, and Trahan's hometown, Westford. A Democrat, she formerly served as chief of staff to Representative Marty Meehan in Massachusetts's 5th congressional district.

Trahan was born on October 27, 1973, and raised in Lowell, Massachusetts. She grew up with three sisters. Trahan attended Lowell High School, into whose Sports Hall of Fame she was later inducted. Trahan has said her family lived "paycheck to paycheck". Her father, Tony Loureiro, had Portuguese parents. His father was from Porto, and his mother was born in Brazil to Portuguese parents and moved to the Azores to live with relatives as a child after her mother's death. Trahan's mother is also of partial Portuguese ancestry (from the Azores).

At Lowell High, Trahan earned an athletic scholarship in volleyball to Georgetown University. She graduated from Georgetown's Walsh School of Foreign Service with a bachelor's degree in comparative and regional studies in international relations.

After college, Trahan worked for Marty Meehan, the U.S. Representative for Massachusetts's 5th congressional district, eventually becoming his chief of staff. In 2005, she left the public sector to work for ChoiceStream, a Cambridge, Massachusetts–based marketing software company. She became the CEO of the Concire Leadership Institute, a small, woman-owned consulting firm.

In October 2017, Trahan announced her candidacy for the 2018 election to succeed retiring U.S. representative Niki Tsongas. Tsongas had succeeded Trahan's former boss, Meehan, in a 2007 special election (the district was renumbered as the 3rd district after the 2010 census).

In September 2018, Trahan won the Democratic primary election, the real contest in this heavily Democratic district, narrowly defeating Daniel Koh, the former chief of staff to Boston mayor Marty Walsh, in a field of 10 candidates. The victory was upheld after a recount. In the November general election, Trahan defeated the Republican nominee, Rick Green, with 62% of the vote.

Trahan was reelected with 97% of the vote in 2020, running unopposed.

In 2022, Trahan was reelected with 63.6% of the vote, defeating Republican challenger Dean Tran.
