History + Values

In the 1920s, Detroit was in the midst of an intense building boom; so was builder Edward V. Monahan. In 1922, he set in motion an extraordinary family business that continues today. Throughout our history we have developed talent and technology to achieve our customers’ goals. The Monahans of our future carry on the dedication and personal service that has been our hallmark for so many years. Whatever building challenges lie ahead for you, there will always be a Monahan dedicated to your success.
