About Us: RK History

Back in 1963, Ron Kinning started RK Mechanical in Pender, Nebraska. He successfully grew the small, family-owned business and relocated it to Norfolk, Nebraska in 1969. After moving his family to Colorado, RK Mechanical was incorporated in Denver in 1985. His oldest son, Rick, worked in the family business and aided its Denver expansion. In 1999, RK purchased the site of its current Denver headquarters in Stapleton from the City and County of Denver.

Rick Kinning has been the long-standing CEO, and his brother Jon Kinning has been the COO for many years. Under their leadership, this second-generation family-owned business has grown to become one of the Rocky Mountain region’s largest mechanical contractors. The RK Mechanical business unit installs HVAC, plumbing and piping systems in commercial construction projects worldwide, including prestigious local buildings that define the Denver skyline.

Today, RK operates four major facilities in Colorado (Denver Henderson and Aurora) as well as in Salt Lake City. The combined facilities comprise over 42 acres and 500,000 square feet of leading-edge office, fabrication and manufacturing space. RK is diversified into seven business units, which collectively offer the largest single source for construction, manufacturing and service solutions.

With around 2,000 employees, RK is one of Colorado’s largest private sector employers. Yet despite its growth, the Kinning family values – putting relationships first, quality, hard work and loyalty – are still the catalyst behind the community spirit alive in RK today.
