Co-Chair of the Firm’s Litigation Practice Group,  Olivia has litigated a wide range of matters for corporations, LLCs, professional service companies and individuals. She specializes in handling disputes involving real estate,  construction projects, employment and FINRA matters. Representing contractors, architectural and engineering firms and property developers and owners, her experience includes design and construction defect claims; issues involving subcontractors; mechanics’ liens; and claims involving breach of contract, fraud, theft, negligence, misrepresentations and damage to property.   Representing employers, financial advisors and others subject to regulatory inquiries, her experience includes issues involving state and Federal fair labor standards; trade secret misappropriation; claims involving breach of fiduciary duty, breach of contract, misrepresentation, and claims involving investment advisors and registered representatives. 

When law and technology collide, Olivia serves as a resource to the firm and its clients on electronic discovery. She works with colleagues and clients to assess and address legal obligations and avoid potential issues surrounding the preservation and handling of electronic information. In the context of litigation, Olivia assists with the preservation, production and acquisition of electronic information. As the business world increasingly goes “paperless” and the volume of electronically stored information grows exponentially, Olivia ensures that no client falls behind the technology curve. A great advocate for her clients, Olivia also teaches negotiation techniques at the University of Wisconsin.
