Andy Drumheller is at his best in a crisis. For more than twenty-four years, he has helped clients work – and often fight – their way through times of intense difficulty and trouble. Andy understands the value that seasoned, calm judgment can bring to the most important problems his many clients have experienced.
Andy’s professional versatility is difficult to match, even in a large and diverse community like Houston. He has extensive trial experience in the areas of white-collar criminal defense, complex commercial litigation and other disputes involving everything from publication rights and point-of-sale technology to breach of contract and oil and gas royalty fights. He also has substantial experience conducting internal investigations for educational institutions, public agencies and private companies.
Andy understands the importance of successfully balancing the needs and demands of clients’ widely divergent but equally important cases. For example, he represented a citizen charged with murder who was acquitted by a jury for acting in self-defense. At the same time, Andy was significantly involved in the defense of a professional athlete facing a Congressional investigation and threat of prosecution. Moving seamlessly from the extremes of highly-contested matters at their most critical stage to controversies just beginning to brew is a challenge Andy embraces.
Andy focused on getting trial experience immediately out of law school. He worked as an Assistant District Attorney in the Trial Bureau of the Harris County District Attorney’s Office. After nearly three years in that position, Andy met Rusty Hardin and joined him at Rusty Hardin & Associates, where he became a partner and litigated high-stakes matters on behalf of public figures, large organizations with global interests, as well as small, local businesses and private individuals. While working there, Andy had the honor of leading an investigation for a Court of Inquiry that exposed the conduct of a district attorney who hid evidence during the prosecution of an innocent man for a highly publicized murder. He also represented a state legislative committee investigating the actions of a university regent.
Andy is known for paying close attention to his clients and the details of their cases. His judgment about how to proceed in even the most unusual situations and his unique portfolio of case experience make him an excellent problem solver and tireless advocate. Together with his partners at DHM, Andy offers clients a wealth of high-level experience within the flexible and adaptable environment of a boutique firm.
