Mike Petrino is a commercial and appellate litigator with substantial experience in complex civil litigation matters in a number of different forums, including before state and federal trial courts, bankruptcy courts, federal courts of appeals, federal agencies, and arbitrators.

Mike is a generalist, who has litigated a wide variety of issues including breach of contract, trade secret misappropriation, breach of non-compete and non-solicitation covenants, breach of fiduciary duty, tortious interference, unfair and deceptive trade practices claims, and numerous other types of business tort claims, in addition to federal statutory causes of action under the U.S. Bankruptcy Code, the Clean Air Act, and the Clean Water Act.

His prior matters have ranged in size from small matters with less than $1 million at issue to very large multi-district litigations and class actions with billions of dollars at stake.  He has represented individuals and corporate clients from a broad range of industries including vehicle manufacturing, oil and gas, medical devices, power generation and transmission, aerospace, and professional consulting services.  In a number of these matters, he was litigating on behalf of private equity firms or their portfolio companies.

Before joining Stein Mitchell, Mike was a litigation partner in the Washington, D.C., office of Kirkland & Ellis LLP.  Before that, he clerked for Hon. Edith H. Jones on the U.S. Court of Appeals for the Fifth Circuit.
