Norman, Okla., – Cardinal Engineering is proud to announce its thirtieth year as a leading civil engineering company in Oklahoma. 30 years ago, in 1989, Steve Mason founded Cardinal Engineering based on several key fundamental principles. Those principals included having a work environment that created a good balance of blending relationships with family, employees, friends, and clients. He believed that a healthy, educated, experienced and happy work force would be highly successful and better equipped to best serve our clients. In the subsequent years of Cardinal’s growth and diversification, Mason surrounded himself with leadership and staff holding steadfast to those same principles.
