The D.C. Chamber of Commerce on Thursday announced that its president and chief executive, Barbara Lang, plans to resign after more than 11 years at the helm of the organization.

“I love what I do, and it is inspiring to see our members and the business community grow, develop and prosper,” Lang said in a statement. “We’ve made tremendous progress as an organization and as a business community, but it’s time for my next journey.”

Chamber spokesman Brian Boyer said the organization has not yet identified a successor. The organization has retained an executive search firm to help select somone, a process Boyer estimated would take 6 to 9 months. Lang will stay on until that person has been chosen.

Lang has long been regarded as a champion of business in the city. She said one of her proudest accomplishments during her tenure was to grow the Chamber’s membership base to include not just the city’s small businesses, but also larger organizations.

Before working at the Chamber, Lang worked for at District-based Fannie Mae and at technology and consulting giant IBM.
