After playing college baseball for the Georgia Tech Yellow Jackets, Duncan played professional baseball for six years until a shoulder injury forced him to retire. He went into business and was elected to the Georgia House in 2012.
Duncan attended Georgia Institute of Technology, and played college baseball for the Georgia Tech Yellow Jackets. He played in Minor League Baseball for the Florida Marlins organization from 1996 through 2000, reaching Triple-A, when a shoulder injury ended his career.  Duncan retired from baseball and went into business. 
After retiring from baseball, Duncan and his wife, Brooke, started a small marketing company out of their living room. They ultimately grew the company to a full-scale operation in a 10,000 square foot facility and employed over 100 people. The company was eventually sold,[ citation needed] and Duncan later became chief executive officer for Wellview Health, a healthcare and wellness company. 
Duncan was elected to the Georgia House of Representatives in 2012. 
Duncan announced he would run for lieutenant governor of Georgia on April 10, 2017.  He resigned from the Georgia House in September 2017 to focus on running for lieutenant governor in 2018.   Duncan's campaign was centered around his "Policy Over Politics" message and focused on ethics reform and fiscal conservatism. Duncan criticized large tax increases passed by the state legislature, including what is known as the Gas Tax, considered to be the largest tax increase in Georgia. This became a central issue during the campaign, as David Shafer--Duncan's primary opponent--led the conference committee that wrote the Gas Tax (HB 170) and fought for its passage in the Senate.[ citation needed]
On May 22, 2018, Shafer received 48.9% of the vote in the Republican primary with Duncan coming in second place with 26.6%. Since no candidate received a majority of votes, the election then went to a runoff held on July 24.  The runoff election focused largely on Shafer's record at the capitol and a number of ethical questions surrounding his candidacy.  On July 24, Duncan defeated Shafer  with 50.16% of the vote. He narrowly defeated Democratic nominee Sarah Riggs Amico in the general election, receiving nearly 52% of the vote and avoiding another runoff.
Duncan was inaugurated lieutenant governor on January 14, 2019. He is the second Republican lieutenant governor in the state's history.
Duncan is married to his high school sweetheart, Brooke Duncan. They have three sons and reside in Forsyth County, Georgia. The Duncans are active members of Browns Bridge Community Church in Cumming, Georgia.
