Much of the work Cliff does is behind the scenes, improving data handling systems, and finding ways to get the job done more quickly and easily, with ever improving quality.  As you will see when you work with us, Cliff achieves these goals on a continuous basis. In his spare time, Cliff is a marathon runner, mountain and road biker and a proud husband and father.
