Our Story
Allegiance Corporation is a Portland Oregon based commercial concrete construction company founded in 2004 providing quality concrete construction for both general contractors and owners. As a private non-union company, Allegiance Corporation has developed a solid reputation of constructing projects on time meeting schedule deadlines, all in a safe manner, for a very competitive price. Over the years we have built from the Oregon coast to central Oregon and from central Washington to Klamath Falls, Oregon. We are blessed to say the majority of our work is with repeat customers.
