As trial attorneys, we resolve the most contentious problems our clients face, as efficiently as we can.  We do so before trial, if possible, or at trial, if necessary.  Posternak attorneys enjoy trying cases and regularly litigate a wide range of business disputes, employment issues, professional liability matters, insurance coverage and bad faith cases, and other civil suits.  We encourage our clients to take an active role in the resolution of their cases.  We believe that our clients ought to be involved in all significant aspects of a case and that a knowledgeable client’s input is critical to a successful outcome.

Our business trial attorneys litigate disputes involving contracts of all types, intellectual property issues, breaches of non-compete obligations, securities and real estate transactions, regulatory and non-regulatory health care concerns, environmental claims, bankruptcy proceedings, and many other kinds of commercial matters.  Our employment attorneys navigate clients through the maze of statutory and non-statutory constraints on implementing employment decisions.  Where necessary, we also represent clients against charges of discrimination before administrative agencies and courts.

Posternak is counsel of choice for the defense and trial of legal malpractice and other complex professional liability and errors and omissions cases.  Posternak attorneys also have argued many of the most significant appellate decisions in legal malpractice and other professional liability areas.  In addition to defending insureds, we regularly act for insurers as coverage counsel and as trial and appellate counsel in coverage and bad faith litigation.  Posternak also handles the defense of complex product liability disputes, including cases arising out of the use of advanced medical devices.
