Early project experience included historically significant buildings such as Jewell School, Astoria City Hall Renovation, Astoria Performing Arts Center and the Columbia River Maritime Museum, to name a few. That early foundation of experience has helped develop Helligso Construction Co. to become one of the areas larger commercial building contracting firms. The added dedication of the entire team and ability to meet and exceed the technical and managerial requirements of the market has kept our company in a competitive role regionally.

In 2013, and after 35yrs, the transition if ownership will be complete and son Ryan Helligso and his wife Brandi will look forward to the next generation of projects. The continuing company goal will be: to provide a consistent, competitive, full construction service for our NW Oregon and SW Washington clients.
