In 2009, former Chief Counsel for the Internal Revenue Service, Donald L. Korb joined Sullivan & Cromwell as a partner and the head of the Firm’s Tax Controversy Practice. A practicing attorney for over 44 years, both in the public and private sectors, not only is Mr. Korb widely recognized as one of the country’s foremost tax lawyers, his reputation extends outside the U.S. as well. As IRS Chief Counsel (2004-2008), Mr. Korb was the chief law officer for the IRS, supervising approximately 1,500 attorneys who were assigned to the IRS National Office and among the major operational divisions of the agency. He played a prominent role in increasing the effectiveness of the Chief Counsel’s Office, and is best known for developing the litigation strategy that led to the stunning success by the government in litigating tax shelter cases during his almost five-year tenure. 1977, Georgetown University Law Center, LL.M. 1973, Case Western Reserve University School of Law, J.D. 1970, John Carroll University, B.A.
