Marshall Orson says will not seek another term on the DeKalb County Board of Education after a decade of service.

Instead, he’s running for a seat on the DeKalb County Commission.

“I am proud we have made substantial improvements in DeKalb over the last 10 years,” he said Thursday in a Facebook post touting the district’s improvement in financial management, its academic progress and the leadership of Superintendent Cheryl Watson-Harris.

“There is much more to do but this seems like the right time for a change,” he added.

Orson has been a member of the school board since 2012.

DeKalb County Commissioner Jeff Rader announced this week he will not be seeking reelection to the board after four terms. He was first elected in 2006.

On Friday, Orson announced his candidacy for Rader’s seat. Three other people also qualified for the race: Lauren Alexander, Donald Broussard and Michelle Long Spears. All four candidates are Democrats.

The District 2 seat on the County Commission covers parts of the Brookhaven, Druid Hills and Decatur areas in northwestern DeKalb.
