Seth Moulton was born in Salem, Massachusetts, on October 24, 1978, and grew up next door in Marblehead. After attending the Marblehead public schools, he was accepted to Phillips Academy Andover for high school.
From Andover he went to Harvard College where he graduated in 2001 with a degree in physics. Throughout high school and college, he spent summers repairing boats in Marblehead and working on a shortline railroad in New Hampshire. Seth was the commencement speaker for his college graduation; he spoke about the importance of service, and shortly thereafter, before the terrorist attacks of September 11th, he decided to join the Marines.
Seth started Marine training in January 2002 and deployed to Iraq in early 2003 for the invasion as an infantry platoon commander. He returned to Iraq as a platoon commander in 2004 for the Battle of Najaf, and also worked with the independent Iraqi media. In 2005, Seth served as a liaison to senior Iraqi military and political leaders south of Baghdad for General Petraeus, and managed millions of dollars of construction projects throughout five restive provinces for the general.
After leaving active duty in 2006, Seth was accepted into a joint degree program at Harvard’s Business and Kennedy Schools, and then deployed to Iraq in 2007 to serve again as a Special Assistant to General Petraeus, doing counter-insurgency advising. After returning to Harvard in the fall of 2008, Seth was embedded with Marines in Helmand Province, Afghanistan, as a reporter for Dan Rather the following summer.
Before graduating from Harvard with an MBA and MPA in 2011, Seth worked in the public sector infrastructure group of Goldman Sachs in New York. After graduate school Seth was the Managing Director of Texas Central Railway, a privately-backed project to bring 205-mph high-speed rail service to America. He is currently a co-founder of a healthcare start-up addressing the issues of obesity and diabetes.
