The attorneys at Williams Kastner have an extremely broad base of experience. Our clients benefit not only from our product liability background, but also from our experience in other areas such as personal injury and medical malpractice defense. Several attorneys also have engineering degrees, which is an asset in matters involving mechanical devices, machinery, tools and electrical equipment.

Every product liability attorney at Williams Kastner takes the same practical, cost-conscious approach to handling product liability disputes. Cases are handled from a pragmatic perspective, and our attorneys consistently seek alternative methods for dispute resolution whenever appropriate. When cases do go to trial, our attorneys are well known for their preparation, tenacity, and imagination. The firm’s attorneys pride themselves on the ability to handle complex matters by appropriately utilizing the firm’s extensive resources including paralegals, trained support staff, sophisticated computer resources, and state-of-the-art communications equipment.

We have experience in all areas of product liability law. We represent clients with products in numerous areas, including industrial equipment, consumer goods, pharmaceutical, construction, and chemicals. Williams Kastner attorneys have tried many complex cases involving construction equipment and heavy machinery, including cranes, scaffolding, hoists, and lifts. Over the years, we have developed ample experience in representing clients in mass tort claims, ranging from the Dalkon Shield litigation to asbestos litigation. Our litigation experience includes client and expert witness responsibilities at the local, national, and international level.

Williams Kastner has been delivering legal and business advice to a broad mix of clients since our Seattle office opened in 1929. With more than 65 lawyers in Washington and Oregon, the firm provides national and regional capabilities that offer a client-first approach with a practical sensibility only a local firm can provide.

We are attorneys, paralegals, litigation assistants and professional support staff dedicated to advancing the business and legal objectives of our clients.
