Derek Loeser is a senior member of Keller Rohrback’s nationally recognized Complex Litigation Group and a member of the firm’s Executive Committee. He maintains a national practice prosecuting class action and large scale individual cases, including corporate fraud and misconduct, securities, Employee Retirement Income Security Act (“ERISA”) pension and health plan, breach of fiduciary duty, and investment mismanagement cases. Derek has served as lead and co-lead counsel in large, complex cases in both state and federal courts around the country.
Derek has been a plaintiffs’ attorney for over twenty years. He has a passion for taking on large corporations and holding them accountable for wrongdoing. Through all stages of litigation, including trial, he has helped recover over a billion dollars for institutions, retirement plans, retirees, employees, and consumers. Notable cases include mortgage-backed securities cases on behalf of the Federal Home Loan Banks of Chicago, Indianapolis and Boston, and ERISA class cases representing employees in pension cases against Enron, WorldCom, Countrywide, and Washington Mutual, and health plan cases against major pharmacy benefit managers, insurers, and drug manufacturers.
Many of Derek’s cases have required coordinating with state and federal agencies involved in litigation that parallels cases pursued by Keller Rohrback, including states attorneys general, the Department of Justice, and the Department of Labor. In addition, Derek has extensive experience negotiating complex, multi-party settlements, and coordinating with the many parties and counsel necessary to accomplish this.
Before joining Keller Rohrback, Derek served as a law clerk for the Honorable Michael R. Hogan, U.S. District Court for the District of Oregon, and was a trial attorney in the Employment Litigation Section of the Civil Rights Division of the U.S. Department of Justice in Washington, D.C., where he prosecuted individual and class action employment discrimination cases. He is a frequent speaker at national conferences on class actions, ERISA and other complex litigation topics.
