Williams Kastner is distinguished by its long history representing professionals in proceedings involving claims of breach of professional duty.

We have represented professionals such as engineers, architects, stockbrokers, members of the clergy, corporate officers and directors, land surveyors, attorneys, accountants, insurance agents and brokers, real estate agents and brokers, as well as medical practitioners including physicians, psychologists, dentists, hospitals and other health care providers.

Our firm litigates in all areas of law related to professional claims, including the defense of allegations of negligence, breach of professional rules or ethics, professional membership rights, security law violations, RICO violations, fraud, misrepresentation, Consumer Protection Act violations, breach of contract, antitrust, defamation and other claims. We also defend professionals accused of crimes or misdemeanors.

A number of attorneys in the firm devote a majority of their time to defending professional liability cases. Many of our lawyers have developed special knowledge and skills in the defense of particular claims, e.g., in areas including professional disciplinary board actions and insurance coverage disputes. The firm has lawyers admitted to practice in many states including Alaska, Idaho, Oregon and Washington. We have tried more professional negligence cases to verdict than any other firm in the Northwest and average approximately 30 jury trials per year. We have lawyers who are members of the American College of Trial Lawyers, American Board of Trial Advocates (ABOTA), and the Litigation Counsel of America.

The lawyers who founded this firm established a reputation for excellence in representing professionals. We take pride in continuing this tradition of legal service to our professional clients.
