Dan Malloy was born in Stamford, Conn., where he still resides. He attended Boston College where he earned a bachelor's degree in 1977 and a law degree in 1980.
Malloy spent four years as assistant district attorney in Brooklyn, N.Y., before entering private practice.
Malloy was elected mayor of Stamford in 1995 and served four terms, leaving office in 2009. Malloy was elected Connecticut governor in 2010.
He and his wife, Cathy, have three children.
Dan Malloy has presided over the passage of several pieces of ambitious legislation, including a repeal of the state's death penalty for future crimes, the legalization of medical marijuana and an education reform bill aimed at closing the state's achievement gap between rich and poor students.
His first term also was defined by two storms that each knocked out power to half the state and efforts to balance the budget. His administration nearly balanced the budget by striking a labor savings deal with the state employee unions that included reductions in planned salary increases.
Malloy is a supporter of President Barack Obama and made campaign stops for Obama's re-election campaign in August 2012.
In July 2011, Malloy signed legislation making Connecticut the first state to require companies to provide employees with paid sick leave. The measure requires businesses in the service industry with 50 or more employees to allow workers to accrue one hour of sick time for every 40 hours worked. Backers estimate that 200,000 to 300,000 workers would benefit. Opponents said the law will make Connecticut less competitive.
Malloy is Connecticut's first Democratic governor since William O'Neill left office in 1991. He defeated Republican Tom Foley, a Greenwich businessman, in a close 2010 race.
The former Stamford mayor ran for governor once before, winning the 2006 Democratic Party endorsement at the state convention before losing the gubernatorial primary to New Haven Mayor John DeStefano months later. DeStefano lost to Rell in the general election.
Malloy served as Stamford mayor from 1995 to 2009, making him the longest serving mayor in the city's history. He has been credited with helping the city develop new office buildings and attract more businesses and visitors.
Malloy faced a few controversies as Stamford mayor.
He was accused at one time of giving preferential treatment and awarding contracts to companies that renovated his home while mayor. He was exonerated of any wrongdoing by the state in 2005.
Malloy's claim of job creation also was called into question. During the 2010 gubernatorial primary, Malloy ran campaign ads saying he created 5,000 jobs in Stamford during his 14 years in office. Lamont, however, said Malloy was misrepresenting his record on jobs and, citing state labor statistics, claimed the city lost more than 13,000 jobs during Malloy's reign as mayor.
