"I have known Gary Campbell for over twenty years. Gary did the prototype work on some of my first tools. Besides being creative he helped me with the best methods of manufacturing and the right materials.

"Even after some twenty plus years some of my best selling tools were brought about with Gary's help."

"Since 1985 Campbell Engineering has built at least 35 molds for me at Hennis Enterprises and consulted on countless other projects. Even though Gary has moved his business to the other side of the country from California I still have him build my molds because he knows exactly what I want and how I want it. In my opinion he is the best. If you would like a reference please do not hesitate to call me."

"Campbell Engineering provided engineering support that brought about improvements in both quality of function and appearance to several of our products. Gary Campbell personally designed molds and assembly tooling and set up the production line for our recently released disposable clipper blade cartridge."
