     3. Mark A. Cameli

    Mark Cameli is a widely respected litigator with decades of experience helping individuals and businesses navigate crises, remove obstacles and achieve their goals. He is a shareholder and co-chair of the firm’s White Collar Litigation and Investigations Team, a former member of Reinhart’s board of directors and former co-chair of the firm’s Litigation Practice. Mark serves on the firm’s Inclusive Workplace Committee, where he is its former chair, and he co-chairs the Pro Bono Committee.

    Mark’s extensive experience representing clients includes:

      * Defending companies and individuals in Securities and Exchange Commission (SEC) enforcement actions and conducting internal investigations for securities compliance issues.
      * Serving as a fearless advocate for a broad range of clients in manufacturing, health care, religious organizations, defense contractors and others who are targets or victims of fraud, including government program fraud.
      * Representing companies accused of wrongdoing by whistleblowers, including in the context of qui tam actions.
      * Serving as a mediator in high-stakes and complex disputes and employing strategies to help all parties find common ground.
      * Successfully representing businesses and individuals in complex commercial litigation, including conducting internal investigations and managing large cases through trial and appeal.

    He creates highly practical and reputation-saving strategies and solutions, and – when appropriate – he counsels clients on finding success using low-cost, publicly available resources. Recognized for his achievements both inside and outside of the courtroom, Mark was aptly described in Chambers USA as a “wonderfully talented lawyer with an abundance of common sense.”

        Mark's clients frequently come to him during a point of crisis and rely upon his excellent negotiation skills, as well as his trial and appellate experience as demonstrated in hundreds of civil and criminal cases including a significant number of published cases. However, Mark also offers clients access to preemptive and extremely effective strategic planning designed to mitigate compliance risk. He instructs both professionals and staff members on ways to avoid costly mistakes.

        Prior to joining Reinhart, Mark served as a state prosecutor, then as a member of the Criminal and Civil Divisions of the U.S. Attorney's Office for the Western District of Wisconsin where he became Chief of the Civil Division. Mark was the district' first Affirmative Civil Enforcement Coordinator. This unique professional background gives him valuable, in-depth knowledge and experience with both the prosecution and defense of business tort and fraud-based cases and the creative defense of white collar criminal and civil matters.

        In his work as an Assistant U.S. Attorney, Mark also served as the chief of the Financial Litigation Unit where he tried commercial disputes between the government and third parties. Mark was frequently recognized for his accomplishments — notably by the Attorney General and federal agencies.

        In addition to his legal practice, Mark is a seasoned presenter who speaks to client groups and professional associations on enterprise risk management and best practices. He has shared his skills in trial advocacy as a faculty member for the Attorney General's Advocacy Institute at the U.S. Department of Justice in Washington, D.C., and taught programs sponsored by the Association of Trial Lawyers of America (ATLA), Wisconsin, Ohio and Michigan Bar Associations.

        Away from the office, he has a wide variety of interests. He is both an opera and automotive enthusiast, enjoys spending time with his three daughters and four grandchildren, and is a dedicated purveyor and consumer of good humor.
