Mike Columbo

Businesses and organizations facing litigation against the government require counsel who are sensitive to client strategy and operational realities, have deep knowledge of regulatory processes, can maintain credibility with courts and agencies, and act quickly where timing can determine the outcome. Mike is a California-based trial and appellate litigator who focuses on representing businesses and organizations in high-stakes litigation arising from federal, state, and local regulatory action.

Mike has extensive experience litigating complex regulatory challenges through trial and appeal, often seeking emergency and injunctive relief in affirmative cases arising from regulatory enforcement, administrative decision-making, and government action affecting lawful operations, capital investment, and regulated markets.

The Dhillon Law Group Inc. represents clients across a range of industries, including technology, media, manufacturing, development and construction, agriculture, and other regulated sectors. Mike is frequently engaged where the timing of litigation, the agency’s compliance with procedural requirements, and the permissible scope of agency discretion play a central role and where early strategic decisions can determine the outcome of a dispute. His approach emphasizes efficiently achieving practical outcomes consistent with clients’ long-term goals.

In addition to affirmative challenges to government action, Mike has represented individuals and organizations in regulatory enforcement proceedings, including administrative, civil, and criminal matters. Clients value how this experience gives him a comprehensive understanding of how agencies investigate, enforce, and litigate regulatory issues. It also informs his strategic approach to both defending enforcement actions and pursuing affirmative relief.

Mike is based in the San Francisco Bay Area and represents clients throughout California and nationally.
