Heather B. Sanborn is an American politician and attorney currently representing District 28 (portions of the cities of Portland and Westbrook) in the Maine State Senate. She is a member of the Democratic Party.
Sanborn grew up in Portland and attended Middlebury College where she graduated summa cum laude as the salutatorian of her class in 1997. She received a Master of Science in Educational Leadership from the University of Southern Maine in 2004 and taught high school in Cape Elizabeth, Maine.
Sanborn graduated from the University of Maine School of Law in 2007 where she was the editor-in-chief of the Maine Law Review. She worked as a law clerk to Kermit Lipez on the U.S. Court of Appeals for the First Circuit and as an associate in the litigation department at Ropes & Gray. She has served on the boards of the Portland Development Corporation and University Credit Union.
Sanborn and her husband, Nathan Sanborn, co-own Rising Tide Brewery in Portland, Maine, and Heather serves as the director of business operations. The brewery opened in 2010 and quickly outgrew its initial space, relocating in 2012. As of 2020, Rising Tide employs 29 people and produces 4,500 barrels of beer per year. Sanborn has served as the President of the Maine Brewers' Guild and has drawn on her law background to advocate for breweries around Maine.
Sanborn has drawn on her legal background to advocate for state-level policy changes that benefit Maine's craft beer industry. In collaboration with the Maine Brewer's Guild, she submitted a bill to the 125th Maine Legislature that would permit breweries to sell their products on-site. At the time, breweries in Maine were only permitted to give away small samples of their products, a business model which Sanborn and other industry leaders argued was not conducive to customer interaction and beer tourism. The bill, LD #1889, was signed into law in April 2012.
Sanborn ran unopposed for the 2016 Maine House of Representatives District 43 Democratic primary, and defeated Republican opponent Jeffrey Langholtz 65%-35% in the general election.
In June 2018, Sanborn won a contested primary against Portland City Councilor Jill Duson.
Sanborn ran unopposed in both the Democratic primary and in the general election in 2020 and was therefore elected to her second term representing District 28 in the Maine Senate.
Sanborn co-owns and operates Rising Tide Brewery in Portland with her husband.
