The Address Hill-Facing Firms Recognize
Capitol Hill is where the work happens; K Street is where the business of advocacy lives. OSI puts your firm's address on the corridor every Hill office knows.

K Street has been shorthand for Washington's government-affairs industry for decades. OSI Offices at 1629 K Street NW gives Hill-facing consultants and organizations that address, with Farragut West and Farragut North two minutes away: roughly 10 minutes door-to-door from Capitol South or Union Station. Run your practice from anywhere, meet downtown when it counts, and keep a presence between the Hill and the White House.
