Kenco Engineering: 60 Years of Excellence

Kenco Engineering Company, a family-owned business, has been delivering high-quality products and exceptional service for 60 years. The company is committed to exceeding customer expectations by establishing quality objectives and continually measuring, monitoring, and reviewing them at every level of management. Kenco’s mission is to provide products that conform to customer requirements and deliver them on time at a competitive price. Quality improvement is the most important job of every Kenco employee, and Kenco’s name represents quality to vendors, employees, and valued customers.

The company was founded by Kenneth N. Mills, a registered professional engineer and a graduate of Rice University, who derived many of the mathematical formulas used in petroleum equipment sizing. His work in the design of heavy oil field equipment led him to Tulsa, where he was the Chief Engineer for an oil equipment manufacturer. Kenco was born out of his frustration with trying to assure quality in the equipment he sold. Mr. Mills ran the company alongside his wife, Dorothy, until his death in 1976, when his son Steve Mills took over as President.

Under Steve’s leadership, Kenco introduced products that made it a key supplier to oil companies and OEMs. The entire line of Liquid Level Gauges was introduced, giving Kenco a worldwide presence. Kenco thrived under Steve’s leadership and became an important Tulsa manufacturing company, with a reputation as a trusted and reliable manufacturer of engineered products.

The third generation of family leadership began in the mid-1990s when Steve’s daughter Kristin Ragland and her husband David Ragland joined the company. Ken Mills, Steve’s son, also began serving the company in 2002. Steve continued to maintain a presence at Kenco as Chairman of the Board until his passing in December 2007.

In 2006, Kenco completed a major expansion, moving from its 36-year-old, 37,000 square foot facility to a new facility with 111,000 square feet. The new facility ensures that the management team has adequate space and resources to accomplish its current and future goals.

Today, Kenco employs over 100 people and continues to introduce new products. David Ragland serves as President of the company, Ken Mills serves as International Sales/Marketing Manager, and Chris Nelson serves as Purchasing Manager. The company intends to maintain a strong family legacy, one in which Kenneth, Steve, and Kristin would be proud.

In conclusion, Kenco Engineering Company’s legacy of excellence spans over 60 years. The company’s commitment to quality engineering and manufacturing practices has made it a trusted and reliable manufacturer of engineered products. Kenco continues to thrive under the leadership of the Mills family and will continue to introduce new products to meet the needs of its valued customers.
