Trevor C. Lippman - O'Neil Cannon

A Zealous, Empathetic Advocate

Trevor assists clients in a wide array of personal and business legal disputes. Whether evaluating legal options prior to suit, litigating a multi-million-dollar inheritance dispute, pursuing a claim on behalf of a company for breach of contract, or defending a business against false or exaggerated claims, Trevor prides himself on zealously advocating for his clients’ interests while remaining empathetic and clearly communicating throughout the entire process. He understands that many of his clients have not been through the legal process and this can be a stressful and traumatic experience for them.

Having grown up in a large family in rural Wisconsin before attending undergraduate college in Eau Claire, law school in Madison, and settling down in Milwaukee with his wife and two young son, Trevor has a unique ability to relate to his clients regardless of where they live, what they do, and what circumstances they find themselves in.
