Early Foundation

A family tradition of building caught Larry Helligso at an early age. Years of watching and helping his father Chris (owner at H and H Builders) construct buildings, boats and furniture had Larry drawn to the industry. After serving in the USAF (1971-75), Larry entered the union carpenters apprentice program. Early project experience included the construction of the Columbia River Maritime Museum, Performing Arts Center and Jewell School Campus (all while employed with Mittet Construction). Additional significant projects included the Remodel and renovation of Astoria City Hall (w/ H and H Builders).

Project opportunities were scarce and Larry was able to keep himself employed with the limited project leads and project opportunities. Early market sectors included residential remodels, accessory buildings and limited new home construction.



In 1984 and as the economy was improving, the need to hire employees and establish a more significant business presence Larry Helligso Construction Co was incorporated.

Passing The Tourch

Ryan HelligsoIn 2002 son Ryan joins the company as VP after leaving a 7 year career in the Portland electrical industry. His experience in estimating and project management made an immediate impact on the company and allowing adaptation in the escalating pace of the construction industry and allowing Larry to oversee all field activities. Company goals were to compete in the commercial market, public works and add pre engineered steel buildings on the ever growing resume. In 2008 Helligso joined American Buildings Co group of authorized builders.


Family Business

2008 ushered in Ryans wife Brandi to run daily office manager and accounting duties. The increasing demands of project specific accounting and HR requirements and certified payroll in multiple states made Brandi and a small support staff the perfect fit.



In 2014 and after 36 years Larry retires and looks forward to enjoying his free time with family and his farming activities in Olney, OR.


Today Ryan (president) and Brandi (Sec/Treasure) have approx. 15 employees completing projects on the Oregon coast and SW Washington.
