Washington — The ADA is expanding its footprint in Washington with the purchase of a new office building — steps away from the Senate side of the U.S. Capitol.  

In May, the ADA Board of Trustees unanimously approved the purchase of a building at 400 C Street, NE, on historic Stanton Park, about 2.5 blocks from the Hart Senate Office Building.

The projected completion of the renovation is October 2019.

The American Dental Political Action Committee and Council on Government Affairs were consulted during the evaluation process and both voted unanimously to endorse the proposal. Several ADA leaders also inspected the property.

"The Board is confident that this decision — and the painstaking evaluation that led to it, including consulting with all of our ADA financial advisors — will benefit all ADA members, who over the years have consistently indicated that a strong ADA presence on Capitol Hill is one of the greatest values the Association delivers," said Dr. Joseph P. Crowley, ADA president.

With the addition, the ADA becomes one of only two lobbying organizations in Washington — the other is the Heritage Foundation — with a presence on both the House and Senate side of the U.S. Capitol. In addition to providing office space for ADA Washington staff, the building will also be used to host events highlighting the importance of oral health.

"This office building will enable ADA lobbyists and ADPAC staff to be closer to the Capitol and the daily legislative activities," said Mike Graham, ADA senior vice president, Government Affairs. "In addition, it will be used for social and networking events for various ADA Hill events."

The new building will be the Association's third District of Columbia property, including the 12-story office building at 1111 14th St. NW, which houses ADA Washington Office administrative, communications and government affairs staff, and the townhouse located at 137 C St. SE, which regularly is the site of meetings with members of the House of Representatives and their staff, and also private events.

The ADA has maintained offices and staff in Washington since World War II. With the latest purchase, the Association will be able to lease the entire 12th floor of the 14th Street building to tenants, which is expected to bring additional revenue to the ADA.
