Oregon’s Historical Past

Much of Central Oregon was originally surveyed in the late 1800s and of course Prineville and Moro were the only major cities in those days. That means that sometimes our work involves digging up the past, literally! Many of our customers choose us because of our expertise working with historical records and landmarks.
