Trahan, Lori, 1973-

Lori Ann Loureiro Trahan (born October 27, 1973) is an American politician. A member of the Democratic Party, she has served as the U.S. Representative for Massachusetts's 3rd congressional district since 2019.

Born in Lowell, Massachusetts, she graduated from Lowell High School before earning a B.S. from Georgetown University. After college, Trahan worked for Marty Meehan, member of the United States House of Representatives for Massachusetts's 5th congressional district, eventually becoming his chief of staff. In 2005, Trahan 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. She attended Harvard University in 2013.

In 2018, Trahan was elected to succeed Niki Tsongas in Massachusetts's 3rd congressional district. One of Trahan’s first priorities was to address the devastating opioid epidemic ravaging our nation. She introduced the MATE (Medication Access and Training Expansion) Act, which standardizes addiction training and equips medical professionals with the tools necessary to prevent, identify, treat, and manage patients with opioid and other substance use disorders. With the added detriment of the COVID-19 pandemic, Trahan believes that mental health and substance use disorder must be kept at the forefront of the federal response to COVID-19. Now, serving as a member of the powerful House Committee on Energy and Commerce, Trahan is determined to advocate for Bay State residents on pressing issues, including making healthcare more affordable, addressing climate change, protecting kids online, and fighting disinformation in our media. To further her ability to weigh in on these issues on behalf of the hardworking families she represents, Trahan secured appointments to the Subcommittees on Health, Consumer Protection and Commerce, and Oversight and Investigations.
