Working around the clock, 24 hours a day, seven days a week, the men and women of the AOC Senate Superintendent Office are dedicated to serving the United States Senate by ensuring the historic fabric of the buildings are maintained while meeting modern and evolving workplace needs.

The Senate Superintendent’s Office, led by Superintendent Takis Tzamaras, is comprised of a variety of skills and trades including the operation of the air conditioning, cleaning, labor, electrical, elevator, fire/electronics, health and fitness facilities, masonry, painting and refinishing, plumbing, sheet metal, subway, furniture, upholstery, and wood crafting.

These skilled tradespersons work behind the scenes providing services to the Senate that include: ensuring a safe and comfortable indoor environment; preserving historic structures; maintenance, repair, and construction; and furnishing and care of office suites.

The three primary Senate office buildings, outside of the U.S. Capitol, total more than 2.7 million square feet and include the Russell, Dirksen and Hart Senate Office Buildings.
