MacArthur Associated Consultants

In 1976, the late Robert J. (Bob) MacArthur, PE, founded MacArthur Associated Consultants, LLC (MAC). The firm, located in Oklahoma City, OK began with a focus on military and aviation projects. Bob’s service in both the United States Air Force and Oklahoma Air National Guard contributed to his dedication to the pursuit of excellence, and his dedication to the principles of trust, integrity and unparalleled customer service. Over the years, MAC has grown to be a full-service civil engineering and surveying firm, led by over 40 professionals. MacArthur’s Corporate Headquarters is located in Edmond, Oklahoma and MAC’s Bridge Division is located in Norman, Oklahoma. Inspired by MacArthur’s original vision, the MAC team approaches each and every project with a vision of engineering a tradition of excellence.
