Testimonials

Joe Turecek
Director of Construction, Nebraska Methodist Health System

It was one of the best, collaborative teams we’ve had on a project in a long time.

Dave Eppert
Kreg Tool Company

Graham is an excellent partner for us. The team I work with is super organized, quick with responses and keeps everything on schedule and budget. They are also willing to help out in any other way we may need. They have been an excellent resource throughout the project.

Steve Cusher
Hospital Administrator, UnityPoint Marshalltown

I love working with Graham. They have a high level of professionalism. This professionalism trickles down to the subs they use to give an overall great experience with construction. When you have Graham, they don’t just work for you, they are your partner.

Dr. Dan Ryan
President, Dowling Catholic

Graham far exceeded all of our expectations. They are ultimate professionals, from the executives of the company through the subs they hire. Graham managed every phase of the project like it was their building and their money. The job was never complete for them unless we were completely satisfied with all facets of the work.

Mike O’Brien
Senior Project Manager, Corteva

Graham Construction always puts our best interest ahead of their profits. They have a culture of honesty that starts at the top. I know I can always count on Graham to get the job done right.

Rhonda Distefano
VP of Construction, Facility Management and Enviornmental Services, Immanuel

I wanted to thank you and the entire Graham team for a fantastic effort on the Deerfield Renovation.  We couldn’t be more pleased with the project.  The attention to detail and team communication were second to none.  The commitments made by Graham were totally fulfilled.
