Doug Duncan

City of Rockville Mayor After serving three terms as Rockville City Councilman, Duncan ran for Mayor of Rockville in 1987, beating incumbent Steven VanGrack. During his six years as Mayor, Doug started the process of redevelopment in downtown Rockville, which included tearing down the Rockville Mall. That project would serve as inspiration for his revitalization of downtown Silver Spring years later as Montgomery County Executive. Accomplishments under the Duncan administration include building Wootton Parkway and Gude Drive bridge.

Montgomery County Executive Duncan successfully ran for Montgomery County Executive in 1994, defeating Councilman Bruce Adams by nine percentage points in the Democratic Primary Duncan would go on to be re-elected twice for a then unprecedented three terms as County Executive.

Amongst his many awards and accolades during his tenure, one of the most notable was being named Washingtonian of the Year in 2002.

During the campaign, Duncan trailed O'Malley and Ehrlich in fundraising. Duncan began airing television ads in May 2006, relatively early in the campaign season; his poll numbers began to rise in the following weeks.

On June 22, 2006, Duncan unexpectedly dropped out of the race citing a diagnosis of clinical depression. During the brief announcement of his withdrawal, he said that he had at first thought he was simply experiencing physical and mental fatigue associated with campaigning, but that the symptoms had progressed beyond simple fatigue, and sought medical treatment which resulted in the depression diagnosis. He cited a family history of the disease as a factor in the diagnosis, and a number of aides and political associates were quoted in the press saying that Duncan was noticeably unhappy in the period leading up to his withdrawal. During his withdrawal announcement, Duncan endorsed his Democratic primary opponent, Martin O'Malley, in the latter's race against incumbent Republican Governor Robert Ehrlich. At the time of the announcement, polls showed Duncan closing in on O'Malley even as his fundraising was beginning to decline. This weakness in fundraising had led to speculation that Duncan would drop out during the summer, even before the announcement of the depression diagnosis. Reports at the time suggested that his dropping out would have a significant effect on state politics, making it easier for O'Malley to unseat Ehrlich and lowering turnout in the Democratic primary, thereby affecting down ballot races as well. O'Malley won the election and became governor.

In an April 2009 Baltimore Sun article, Duncan proclaimed, "I'm living proof that treatment works."

University of Maryland and after On March 22, 2007, Duncan was appointed Vice President of Administrative Affairs at the University of Maryland, College Park, effective April 4, making him the university's chief administrative and finance officer with authority over the university's human resources, comptroller, public safety, facilities and environmental management, and procurement. During his tenure, Duncan led the East Campus redevelopment project, designed as a mixed-use town center with graduate student housing along the Route 1 corridor. In association with the project, he also worked to improve relations between the university and the surrounding city of College Park. On October 15, 2008, after a seventeen-month tenure, Duncan announced his resignation from the University of Maryland.

After Maryland, Duncan was self-employed as a consultant advising various enterprises in Greater Washington D.C. Metro Region and beyond regarding economic development, technology and immigration issues. In 2010, Duncan was speculated as being in consideration for General Manager of WMATA, after John Catoe vacated the post, including receiving an endorsement from then Congressman, and now United States Senator Chris Van Hollen.

2014 Race for Montgomery County Executive In 2014, Duncan made his political comeback seeking to reclaim his old post at Montgomery County, Maryland Executive for a fourth term. Running on a platform of "Leadership In Action" with ideas of revitalizing downtown Wheaton, better attract and keep jobs and business with an improved procurement process and more "open for business" attitude, create express lanes on I-270, build a technology institute venture similar to that of Cornell and New York City, and provide gigabit internet speeds across the county. He lost in the Democratic primary on June 24 to incumbent Ike Leggett.

Leadership Greater Washington Shortly after his campaign, Duncan was selected as president and CEO of Leadership Greater Washington, a non-profit organization with a mission to bring leaders together to make positive community impact in the Washington Metropolitan region. The vision for LGW is to help the Washington Metropolitan become a more dynamic and collaborative community with engaged leaders of diverse backgrounds, geographies, and sectors through dynamic, education and membership programs that promote dialogue and cooperation, enabling area leaders to find effective solutions to regional challenges. He still serves in this role today. In this new role, Duncan was named to Washington Business Journal's Power 100 for 2014 and 2015.

Continued involvement in politics Despite being out of political office since 2006, Duncan has remained politically active in Maryland and the Washington region.

In 2012, Duncan endorsed then upstart and underdog John Delaney in his first bid for Congress; "Duncan's endorsement was the first of any consequence, and he backed up his support by cutting radio spots for Delaney and going door to door with him".

In 2014, Duncan was named to newly elected Maryland Governor Larry Hogan's transition team as well as that of newly elected District of Columbia Mayor Muriel Bowser.

In 2018, Duncan endorsed David Trone, who was elected to Congress later that year.

Personal life Duncan married wife, Barbara, on June 14, 1980, on the campus of Trinity College in Washington, D.C., where Barbara went to school. They met in 1978, as Barbara worked for Doug's mom, Ellie, at the Montgomery County Circuit Court. They live in Rockville, Maryland, and have five grown children and two grandchildren.

In popular culture Duncan is portrayed by Jay O. Sanders in the 2003 film, D.C. Sniper: 23 Days of Fear.
