Ken Clifford began his career as a mechanic and eventually went to work for United Engines, specializing in oil field sales applications such as drilling rigs, frack units and generators. During this time he gained significant experience in the mechanical applications of original equipment manufacturing (OEM). With strong results in this role, it quickly became evident that Clifford excelled in industrial sales and he was promoted to lead a team of sales engineers within the company.

While at United Engines, Clifford was approached to explore the opportunity to serve as a Generac distributor. After convincing his employer that this was a great line of business to expand into, he was given the oversight to grow this business, which he did successfully. This experience led him to realize the market potential of the product, so he pursued starting his own Generac distributorship.

In April 1985, along with his father and armed with a very small financial stake, Ken Clifford opened Clifford Power Systems in Tulsa, Oklahoma. Two months later they were joined by his brother Tom. In the early years, Ken Clifford’s deep technical knowledge and sales expertise proved invaluable since the three Cliffords were the company's sole employees. From these humble beginnings, the Cliffords established the foundation for a company that now comprises 10 office locations; provides a full complement of life-cycle generator solutions including sales, service, rental and parts; employs more than 165 professionals; and has annual revenues in excess of $35 million.

Today, Clifford is retired and serves on the board of directors for Clifford Power Systems with his brother Tom. In this role, he is an advisory member of our leadership team and is instrumental in collectively determining the outcomes and direction for Clifford Power Systems. Clifford also works closely with the company's legal counsel and develops and maintains relationships with key partners.

The Clifford brothers have founded many ventures in addition to Clifford Power Systems, including LUXA Enterprises, which provides outsourced solutions for accounting, payroll, human resources and marketing; XTC Land Company; ConstructComm LLC; Ultimate Service Associates Inc.; and ReVolt LLC.

Tom Clifford began his career by attending Kettering University — formerly General Motors Institute. This unique industrial engineering program combined academics with application by alternating six weeks of traditional classroom education with six weeks of internship in various departments at a General Motors facility. By the time Clifford graduated with his bachelor's degree, he possessed a firm foundation of industrial engineering principles and real-life experiences in every aspect of management and operations for a large industrial operation.

Upon graduation, Clifford served as a product expert for a heavy equipment transmission line for Detroit Diesel Allison, a division of General Motors. In this capacity, he was responsible for working with the engineering and manufacturing staff to resolve issues encountered by dealers and owners in the field. Within a year and a half, he was promoted to serve as a regional service representative with oversight of two distributorships in relationship to their provision of General Motor products. In this role, he oversaw every aspect of distributorship operations including customer service, parts, sales, complaint resolution, business administration and strategic business plan development.

In 1985, Ken Clifford and his father started Clifford Power Systems as a sole distributorship of Generac products in Tulsa, Oklahoma. Within two months, Tom Clifford joined them in business. In the early years, Tom Clifford’s experience in all aspects of business and operations, as well as his knowledge of engines, was invaluable as the three Cliffords were the company's sole employees and were directly involved in sales, administration and technical support. From these humble beginnings, the Cliffords established a foundation for a company that now comprises 10 office locations; provides a full complement of life-cycle generator solutions including sales, service, rental and parts; employs more than 165 professionals; and has annual revenues in excess of $35 million.

Today, Clifford is retired and serves on the board of directors for Clifford Power Systems with his brother Ken. In this role, he is an advisory member of our leadership team and is instrumental in collectively determining the outcomes and direction for Clifford Power Systems. He also works closely with the company's legal counsel and develops and maintains relationships with key partners.
