Testimonials from the people using a company’s products and services are often one of the strongest ways to highlight the value and strengths in that company’s offerings. Bill Johnson, a field technical engineer with Firestone Specialty Products, has shared a comment on Demtech Services Inc., a maker of welding equipment and other materials used in the installation of geosynthetics, such as the geomembranes produced by Firestone. Addressing Demtech’s “Demo Dave” McLaury, Johnson commented: “Demtech equipment is innovative and your energy is infectious. Those of us who benefit from your continual strides forward appreciate all you do for our industry.”
