Brian Dillon

Brian Dillon concentrates his practice on complex business litigation, trusts and estates litigation, and administrative and regulatory defense. Clients value Brian’s diverse range of litigation experience, which gives him a broad legal perspective that is unmatched by most of his peers.

In complex business litigation, Brian focuses on resolving shareholder disputes and other disputes among closely held and family-owned business owners. Brian regularly advises businesses and their officers, directors, and shareholders involved in disputes over corporate governance, treatment of minority shareholders, use and misuse of corporate funds, and business succession plans. Brian has extensive experience prosecuting and defending cases involving claims of fraud, embezzlement, unfair competition, and breach of fiduciary duty. Brian’s clients in this area come from all types of industries and include product manufacturers, financial service companies, IT service providers, software developers, health care companies, government contractors, and real estate developers.

Brian also practices extensively in probate and U.S. Tax Court, helping to resolve disputes over the administration of trusts or estates, will contests, and matters of guardianship and conservatorship. Brian’s deep familiarity with probate and U.S. Tax Court procedure ensures that his clients’ interests are protected, and his down-to-earth manner comforts and supports clients through these matters, which are often charged with emotion.

In the administrative and regulatory space, Brian helps clients conduct internal investigations and respond to external ones.  He defends clients who are subject to government enforcement and licensing actions, and he helps them develop and implement effective compliance programs. Brian also has substantial skill in state and federal campaign finance laws and is regularly called upon to advise nonprofit advocacy organizations on political advocacy campaigns.

Brian also leads the firm’s eDiscovery: Data, Records & Information Governance team.  In that role, Brian helps clients develop document retention policies and procedures that are appropriate for their business needs and is regularly called upon to help navigate the increasingly expensive electronic discovery process in a creative and cost-effective manner.

Before joining the firm, Brian served as an assistant attorney general in the Minnesota Attorney General’s Office, where he prosecuted cases under Minnesota’s health, consumer protection, financial services, and antitrust laws. Brian is a Wisconsin native and regularly practices in Wisconsin courts.

Outside of work, Brian enjoys recreational sports of all kinds, fishing, backpacking, and spending time with his family.
