For nearly two decades, Don McBride has focused his practice on representing broker-dealers, registered investment advisers and individual investment professionals in a wide array of litigation and regulatory matters throughout the United States. He has extensive experience defending customer disputes in federal and state courts, as well as in arbitrations before the Financial Industry Regulatory Authority (FINRA). Don also represents clients in regulatory investigations and enforcement proceedings before FINRA, the U.S. Securities and Exchange Commission and state securities regulators.

Don’s goal is to provide practical advice to his clients, knowing that they operate in a highly regulated industry, and guide them to successful outcomes. At times that involves negotiating fair and appropriate resolutions, taking into account the total cost of defending a matter, collateral consequences or reportable events, and how litigating may affect a client’s business. Other times he has fought for clients before juries in state court, or tried matters to final hearing before FINRA arbitration panels. He has also argued before the Missouri Court of Appeals Eastern and Western Districts, and the Florida District Courts of Appeal.

Don also serves as an arbitrator, a role that provides insight on how panels decide discovery disputes, weigh evidence and make their final decisions.

Prior to joining Armstrong Teasdale, Don was the Co-Chair of the Financial Services Industry Group of his previous law firm, and prior to that he worked in the mutual funds department of a nationally known brokerage firm in St. Louis, where he gained first-hand knowledge of the securities industry.
