About me

Ten years in the construction business tells me that the best legal answers inevitably involve an objective assessment of what makes the most sense for the client's business. My name is Tymon Berger (pronounced tim-min), and I have represented contractors in complex construction disputes ranging from highways and bridges to schools and ball parks. I have also advised clients on several high-profile private developments in the Puget Sound area. And I help contractors with federal and state bid protests, as well as bond, lien, and retainage claims against federal, state, and private projects. Although I primarily represent contractors on large public and private projects, I have had equal success representing contractors, owners, and homeowners on smaller projects.
