OUR EXPERIENCE

WHAT OUR CLIENTS SAY
Gideon's attentiveness to our needs and overall professionalism made the project a success and it was a pleasure to work with them. As with any design-build, there can be many change orders to manage. The Gideon team remained flexible, offered solutions when we asked for last-minute changes and, despite multiple weather event disruptions, kept the project on time and on budget. We love our new manufacturing facility.
