Doug has been actively engaged in cases involving financial service institutions, broker-dealers and corporate executives relating to securities, derivative products and other complex financial instruments. In this regard, he has advised and defended companies and corporate executives in virtually all types of inquiries by civil and criminal authorities (as well as SROs) into business practices on Wall Street, including a wide array of matters involving the financial crisis. Doug has also handled major civil litigations and arbitrations involving a broad spectrum of substantive legal issues, including fraud, breach of contract, breach of fiduciary duty, reinsurance, piercing the corporate veil, mergers and acquisitions, and money laundering, as well as federal securities law. Additionally, Doug has handled numerous civil and criminal matters involving allegations of antitrust violations.
Doug has been recognized as a leading lawyer by Chambers USA, which noted that he is “hard working, attentive and client-focused,” “extraordinarily focused and tenacious,” and “a smart, thorough litigator who is always on top of things.” Chambers also noted that he “has everything on his radar screen” and has a “remarkable ability to get along with anyone, making it his business to develop a rapport with other attorneys involved in his cases.”
Represented a former Equifax executive in a widely publicized insider trading case brought by the U.S. Attorney’s Office and the SEC, both for the Northern District of Georgia. The executive is alleged to have traded on material non-public information before the company’s announcement last year that it had suffered a data breach.
Represented a leading global clinical research organization (CRO), as respondent, in a four and a half year-long arbitration proceeding brought by a biopharmaceutical company.

After a more than 50-day arbitration trial, the arbitrator issued a final award denying virtually all of the claimant’s allegations, including denying all of its fraud claims. After making certain deductions based on a counterclaim on which Doug’s client prevailed, the arbitrator issued a net award to the claimant of approximately only 0.2 percent of the amount it sought.
