Client Testimonials

"Brian and Allison Long, owners of Long’s Drilling Service Inc., have been longtime friends and customers of Center Rock Inc. When they call for tooling quotes they are very precise as to what the project calls for: number of holes, diameters, depths, amount of overburden, rock socket requirement, rock hardness, schedule…
They have been a valuable resource for Center Rock Inc for improving our products. Their suggestions have lead to several improvements in the application of our products."
