Denier is a family-owned business with a rich history that goes back nearly 8 decades. The business started as a small electrical contractor business but has grown into a multi-division business capable of meeting the needs of just about any construction project.
In 1942, Denier Electric is founded in Cincinnati by Howard Denier with just one employee.
In 1969, Denier invents the hydraulic scissors lift – proudly proclaiming it was “built by electricians”– and introduces it to the construction industry in 1970.
In 1974, Denier becomes a 2nd generation business when Dennis Denier, who started as an electrician helper in 1963, assumes the role of President. The company steadily grows to 250 employees under his leadership.
In 1980, in anticipation of the industry moving away from traditional spec-bid construction to fast-track, design/build projects, Denier starts its own in-house engineering firm, which propels it to the forefront of design-build electrical contracting.
In the early 1980’s, Denier starts its own prefabrication shop as a way to help fast-track projects. This leads to the establishment of Denier Manufacturing, a sheet metal fabrication shop, and then to the development of Rough-in Ready in 2002, a nationally marketed, UL listed prefabricated wiring system.
In 1988, Denier opens a Columbus office with full electrical, engineering, and service departments to handle a growing list of projects in the Ohio region.
In 1989, Denier is the first Cincinnati electrical contractor to completely design and construct the electrical system for a downtown high rise – 34 stories. The trend continues with the next three high-rise office towers built in Cincinnati.
In 2000, Denier starts its Technologies Division that specializes in structured cabling and low voltage systems.
In 2012, 2nd generation owner, Sandy Feldhaus, is joined by new 3rd generation business owners Susan Laumann, Steven Denier, Daniel Denier, and Katie Koetters.
In 2015, Denier is certified as a WBE by the Woman’s Business Enterprise National Council.
