About

David H. Dickieson is a seasoned attorney based in Washington, bringing over 30 years of extensive litigation experience to his practice. Since joining Schertler & Onorato, LLP in 2007, Mr. Dickieson has made significant contributions to the firm, drawing from his previous role as the head of the Washington litigation team at a prominent national law firm, which expanded to over 500 lawyers during his tenure. Throughout his career, Mr. Dickieson has been at the forefront of complex investigations, personal injury cases, restructuring efforts, and tax litigation across the United States. His notable achievements include representing the UBS whistleblower in a groundbreaking campaign involving the IRS, the Department of Justice Tax Division, the SEC, and the Senate Subcommittee on Investigations. This high-profile case culminated in a remarkable $104 million whistleblower reward and has had a lasting impact on the restructuring of the global cross-border banking system. Mr. Dickieson's legal acumen was further honed during his tenure at the United States Department of Justice Tax Division from 1984 to 1989, where he served as the senior attorney on the largest civil tax fraud case of its time—the In re Conti-Commodity Corp. case. His successful resolution of this case, which involved billions of dollars in phantom commodity trades, paved the way for his transition to private practice with a prestigious national tax law firm. In addition to his impressive track record in tax law, Mr. Dickieson has excelled in various trial settings, including winning a record jury verdict of $7.3 million in a landmark optometric malpractice case. His diverse expertise allows him to adeptly represent clients in Bankruptcy Court, Tax Court, and across state and federal jurisdictions, making him a formidable advocate in the legal landscape.
