Michael Scrivner began his service in the Congress in 1978 when he joined the staff of the late Rep. John J. Duncan, Sr. (R-Tennessee) as legislative assistant and press secretary. Mr. Scrivner assisted Rep. Duncan, then the second ranking member of the House Committee on Ways and Means, with tax and health care issues. He also served as Rep. Duncan's key staffer in the successful effort to exempt the Tennessee Valley Authority's Tellico Dam from coverage under the Endangered Species Act. This celebrated fight over the fate of the snail darter was the major environmental battle of the Carter administration, and it ended in 1980 when the dam went into operation. In 1981, Mr. Scrivner went to work as legislative director for Rep. Norman F. Lent (R-New York), a senior member of the Committee on Energy and Commerce. In that capacity, Mr. Scrivner assisted Rep. Lent on environmental, transportation and commerce issues before the subcommittee on which Lent served as Ranking Republican, and on issues of concern to Long Island's major defense contractors. In 1985, Mr. Scrivner was promoted to the position of chief of staff for Rep. Lent and added staff supervision to his duties while remaining actively involved in legislative issues before the Energy and Commerce Committee. When Rep. Lent became Ranking Republican of the full Committee on Energy and Commerce in 1986, Mr. Scrivner worked as Rep. Lent's primary liaison with the Committee staff on a broad range of issues including the Clean Air Act, Superfund, RCRA, legislation affecting the insurance and securities industries, telecommunications, health care and transportation. In 1993, Mr. Scrivner left Capitol Hill to form the consulting firm of Lent & Scrivner with former Congressman Lent. As a lobbyist, Mr. Scrivner has represented clients and worked to forge legislative solutions primarily in the areas of energy, the environment, telecommunications, health care and pharmaceutical policy.
