Greiner Buildings – Building Relationships on a Foundation of Honesty & Integrity


The Greiner Buildings Team

Greiner Buildings began in the 1980’s by owner, Tom Greiner, in  his hometown of Washington, Iowa. Based on a foundation of honesty and integrity, we have grown to over 35 employees with two additional offices located in Kewanee, Illinois and Des Moines, Iowa. Greiner Buildings has enjoyed being a family owned business and creating solid relationships with our customers. Tom’s son Matt has taken over as President of Greiner Buildings and currently serves on the NFBA Board of Directors. Our company takes pride in using our own crews to construct what we do best – producing an efficient and unique structure to meet your needs. We train and work hard to give you the best built, highest quality product for you to enjoy in the years to come.

The Greiner Buildings Crew

Demonstrating professionalism and expertise throughout the construction process, our crews ensure your project is built to your satisfaction while making sure it is completed safely. Our crews attend multiple training seminars throughout the year covering industry standards and have received the Gold Level Achievement award from the NFBA for their safety program. Greiner Buildings also alleviates the necessity for our customers to carry additional insurance by placing Builders Risk coverage on all projects.
