Keller history

Beginning in 1969, Dale and Jim Keller laid the groundwork for what would become the Keller Construction of today.

J.J. Keller expanded through growth in its safety-publishing niche, entering regulation compliance publishing in 1970.

First incorporated in 1972 as Keller Excavating, the company quickly grew into a multifaceted corporation covering virtually all aspects of heavy construction from heavy highway, road, and bridge construction to utility construction, demolition and earthwork.

Ranked among the 100 largest privately held companies in Wisconsin, J.J. Keller produced sales of $90 million in 1993.

By 1994, the company offered 2,000 regulation compliance associated products and served as a consultant to companies across the country seeking up-to-date information on the DOT, Occupational Safety and Health Administration (OSHA), and Environmental Protection Agency (EPA) rules.

The United States Department of Labor's Bureau of Labor Statistics reported 5.9 million cases of injuries and illness within private industry workplaces in 1998, according to an October PR Newswire article.

In 2001, J.J. Keller produced revenue in excess of $160 million from its 4,000-plus products and services.

Canyon Contracting, Inc., founded in 2003, is a concrete construction company specializing in government, private, and competitively bid public sectors.

Ethel Keller, cofounder and member of the board of directors of J.J. Keller, died at the end of 2004.
