Denier Electric


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.
