Professional Liability

Threats to career and livelihood, professional liability claims call for superior legal guidance. As experienced leaders in the defense of these claims, we have the skills and knowledge to help professionals achieve the best outcome. We bring in-depth knowledge of the legal nuances of these cases, while remaining always sensitive to their financial, professional and personal consequences. We work closely with our clients to familiarize them with the legal process and ensure that they fully understand the case.

Our experience includes:

  • Design professionals. In design cases ranging from slip-and-fall claims to complex commercial construction disputes, our record of success speaks for itself. We are thoroughly experienced in the legal issues, but also in the technical aspects of construction, from pre-design through final completion. In fact, several of our attorneys have educational and career backgrounds in architecture and engineering.
  • Directors and officers. We represent directors and officers in disputes involving all aspects of corporate decision-making. We defend shareholder and derivative claims involving allegations such as breach of fiduciary duty, federal and state securities violations, due diligence, mergers and acquisitions, and general business affairs. Our defense is strengthened by our ability to tap the knowledge of our corporate and insurance attorneys, who are experts in advising corporate clients on these issues.
  • Legal professionals. We defend legal malpractice lawsuits arising from all practice areas, including litigation, family law, wills and estates, business transactions, and intellectual property. We also represent attorneys in grievance proceedings and in suits by non-clients alleging vexatious litigation, abuse of process and similar claims. Our clients include law firms sued as the result of a lawyer’s defalcation.

In addition to defending these cases, we counsel professionals on risk management, helping them avoid or minimize problems before they occur. Our expertise enables us to analyze the professional’s practice and recommend preventive measures.
