Building Integrity

Integrity has been our guiding principle from the day Doug Guillon established the company in 1980. His insistence that “our projects stand on their own merits” has guided us through every phase of every project, transparent business practices, and unreserved accountability.

Building Partnerships

Partnerships have been the cornerstone of our continued success with the mission of creating a highly efficient performance oriented organization. We are committed to representing ourselves and our partners in the utmost professional manner, including the unwillingness to compromise our values.

Building Communities

Creating built environments which benefit the social and economic fabric and health of the community takes well thoughout and timely executed project management. We aggressively pursue building relationships with all involved including project neighbors, government officials, regulatory agencies and partners.

Building Industry

Concrete tilt-up industrial structures were the fundamental begining of Guillon Inc. Industrial buildings serve as economic backbones for communities as they are a source of employers and industry.
