Howard Brush Dean III is an American physician, author, lobbyist, and retired politician who served as governor of Vermont from 1991 to 2003 and chair of the Democratic National Committee from 2005 to 2009. Dean was a candidate for the Democratic nomination in the 2004 presidential election. His implementation of the fifty-state strategy as head of the DNC is credited with the Democratic victories in the 2006 and 2008 elections. Afterward, he became a political commentator and consultant to McKenna Long & Aldridge, a law and lobbying firm.
Before entering politics, Dean earned his medical degree from the Albert Einstein College of Medicine in 1978. Dean served as a member of the Vermont House of Representatives from 1983 to 1986 and as Lieutenant Governor of Vermont from 1987 to 1991. Both were part-time positions that enabled him to continue practicing medicine. In 1991, Dean became governor of Vermont when Richard A. Snelling died in office. Dean was subsequently elected to five two-year terms, serving from 1991 to 2003, making him the second longest-serving governor in Vermont history, after Thomas Chittenden.
