Prior to joining the firm on February 1, 2005, Steve served as Senior Vice President, General Counsel and Secretary of Circuit City Stores, Inc., a Fortune 200 retailer of consumer electronics with approximately $10 billion in annual sales. As Circuit City's chief legal and public policy officer, Steve was responsible for the management of all legal and policy issues including corporate governance, SEC/FCC/FTC regulatory matters, antitrust, consumer credit, mergers and acquisitions/divestitures, litigation, employment, intellectual property as well as government affairs.

In particular, Steve focused his practice in the telecommunications, pharmaceutical and retail industries.

Before joining Wunder, Diefenderfer in 1986, Steve spent 10 years in government service in Washington, D.C. After a clerkship with the South Carolina Supreme Court, Steve received an appointment under the U. S. Justice Department's Honors Law Graduate Program and served as a trial lawyer in the Antitrust Division from 1977 to 1981.

In 1981, Steve was appointed Chief Antitrust Counsel to the United States Senate Judiciary Committee. Serving in this position from 1981-1984 (97th and 98th Congresses), Steve had overall staff responsibility for all antitrust legislation, as well as Department of Justice Antitrust Division oversight. As Chief Antitrust Counsel, he coordinated preparation of antitrust legislation including hearings, committee mark-ups and floor debates. Antitrust legislation enacted by the Congress during Steve's tenure included:
  • The Antitrust Reciprocity Act of 1982 (P.L. 97-393)
  • The National Cooperative Research Act of 1984 (P.L. 98-462)

Steve was also responsible for all Antitrust Division appellate matters and, in this capacity, argued before the United States Supreme Court as amicus curiae on behalf of the United States in 324 Liquor Corp. v. Duffy, 107 SCT 720 (1987).

Over the course of his career, Steve has served in numerous professional, civic and business organizations. Most recently, Steve was appointed by Senate Majority Leader Frist to serve on the Antitrust Modernization Commission. Composed of 12 appointees, the Commission is charged with examining the broad scope of the nation's antitrust laws and determining what, if any, changes might be appropriate and beneficial to our 21st century economy.
