He has litigated cases in the United States Tax Court and federal district courts, successfully defended against government subpoenas for trial and deposition testimony, and also represented business executives testifying about tax matters before courts and congressional committees. Additionally, Michael has counseled multinational corporations under investigation by foreign tax authorities.
Michael advises sophisticated individual and corporate taxpayers in the real estate, financial services, manufacturing, and retail industries. Representative successes include helping secure a trial victory in Amazon.com v.

Michael previously clerked at the Commonwealth Attorney’s Office for Kenton County, Kentucky. Under Kentucky’s limited student practice program, Michael second-chaired two jury trials and presented multiple felony cases in preliminary hearings and in grand jury proceedings.
