ABOUT US
In 1976, the late Robert J. (Bob) MacArthur, PE, founded MacArthur Associated Consultants, LLC (MAC). The firm 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 commitment 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. MAC’s Corporate Headquarters is located in Oklahoma City, and its satellite office is located in Tulsa, Oklahoma. Guided by Bob MacArthur’s original vision, the MAC team delivers every project with the purpose of building a tradition of engineering excellence.
