    Sean Bosack joins Nixon Peabody as partner (PDF)

    Providence, RI. Nixon Peabody LLP has expanded its Complex Disputes practice with the addition of Sean Bosack, who joins the firm as a partner.

    Based in the firm’s Providence office, Sean is an experienced civil and criminal business litigation and trial attorney. He represents corporates and individuals in complex commercial disputes, securities fraud, antitrust, healthcare fraud, Racketeer Influenced and Corrupt Organizations Act (RICO), government and internal investigations, and white-collar criminal defense in federal and state courts and arbitrations nationwide. Sean brings a national practice built on deep substantive knowledge, significant trial experience, and trusted client relationships across banking, financial services, healthcare, manufacturing, and defense industries.

    “Sean brings a breadth of knowledge from his nearly three decades of experience,” said John Ruskusky, leader of Nixon Peabody’s Complex Disputes practice. “His ability to handle various commercial litigation and white-collar investigations will be an immediate benefit to our clients. We are thrilled to welcome Sean to the firm and introduce him to our clients and colleagues.”

    Sean represents clients on a wide variety of complex civil litigation matters including corporate governance, shareholder disputes, securities fraud, RICO, antitrust, trade secrets, unfair competition, and complex contract matters. He advises corporations conducting internal investigations involving fraud and corporate governance issues. Sean also represents corporate and individual clients in white-collar criminal matters, including healthcare fraud, False Claims Act and qui tam actions, export control, and anti-money laundering, as well as the parallel civil and regulatory proceedings that frequently follow.

    “We are excited to continue to expand our litigation capabilities in Providence with the addition of Sean,” said Armando Batastini, managing partner of the firm’s Providence office. “He is an excellent cultural fit and we look forward to him joining the office.”

    Sean earned his JD from Marquette University Law School and his BA from Brown University. He is an elected member of the Council of the ABA Litigation Section.
