Duffie Incorporated







The Duffie Companies are highly focused on their core capabilities and only pursue projects that fit their parameters for excellent results. They are an ideal size to remain agile and flexible, which fosters creativity, but they never lose sight of the details. This combination enables them to derive the greatest value from their efforts, with a contstant emphasis on producing an excellent, high-quality product.

The Company's strength is built upon the knowledge that comes from hands-on experience. All the managers have come up through the ranks, starting in the field by doing construction. Their philosophy that before you can tell someone how to do something, you must know how to do it yourself has served them well in building both their products and their reputation.
