What People are Saying About Diehm & Sons

Whether it’s surveying and mapping, civil engineering or land planning, Diehm & Sons keeps pace with the changing times and deliveries. From executing intricate land surveys to communicating with various municipalities that require complex subdivision plans before a single stake is hammered into the ground, we are committed to the successful outcome of your specific project. Below is just a sample of what our clients have said about us.

My project with Diehm & Sons was both important and time sensitive. We came across the usual hiccups and obstacles but project manager Tom Matteson was able to handle them with ease. On the occasions when Tom was unavailable, his colleagues were quick to assist me. It was like having the whole team working on my project and, at one point, it seemed like they really were! In addition to the talent and timeliness they demonstrated, Diehm & Sons was just a pleasure to work with.
