Commercial Litigation | Construction Law

Mark Rosencrantz’s practice focuses on solving business and commercial disputes for clients throughout the United States. He understands that litigation is a distraction to his clients that prevents them from living their lives and profitably running their businesses. With that in mind, Mark approaches each matter by first working with his clients to identify their issues and goals, and then mapping out an approach designed to accomplish those objectives, whether that be negotiating an early settlement, getting ready for a “bet the company” trial, or anything in between.

Mark has successfully handled cases involving a wide array of large-dollar business and commercial disputes, with particular emphasis on trade secret misappropriation, violations of non-compete agreements, fraud, bankruptcy, unfair trade practices, and partnership and corporate disputes. He has obtained multiple multi-million dollar recoveries for his clients and helped others extricate themselves from potential judgments of the same size. Mark has done so before state and federal courts in Washington, Oregon, Nevada, Texas, Arizona, Idaho, Hawaii, Illinois, and New York.

In construction matters, Mark has represented all levels of contractors, as well as owners, in a wide variety of cases involving construction defects, delay and impact claims, bid protests, and copyright infringement of building plans. He has worked on cases involving projects ranging from commercial buildings to condominium projects. He has obtained both large monetary awards and injunctive relief on behalf of his clients.

In addition to his active practice, Mark serves as an arbitrator in the King County Superior Court Mandatory Arbitration Program, and has written and lectured on a variety of legal and business issues.
