About MAC

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, Oklahoma, and its satellite office is located in Tulsa, Oklahoma. Inspired by Bob MacArthur’s original vision, the MAC team approaches each project with a vision of engineering a tradition of excellence.
