As a Project Manager for Speedie and Associates located in Phoenix, AZ, it has indeed been a pleasure to work with Mr. Don Broton and the talented staff of professioanls at CTL Group in Skokie, Illinois for the past few years. Don always takes the time to patiently explain those numerous sophisticated CTL test procedures on concrete and cement that the great majority of materials testing laboratories do not perform. For those professionals in the concrete industry seeking technical expertise, I would highly encourage and recommend Don Broton and the CTL Group for your atypical testing needs.

I enjoyed working with Don for more than 24 years. He is very knowledgeable, attentive to his clients, and a pleasant person to work with. I appreciated his creativity and eagerness to troubleshoot and find new and better ways solve challenging problems. I highly recommend him as energetic, creative, competent, and trustworthy.
