OUR HISTORY

In 1976, the late Robert J. (Bob) MacArthur founded MacArthur Associated Consultants, LLC (MAC). Bob began the company with only two employees and focused on military and aviation projects. With Bob’s first major airport project in 1976, MAC was well on its way to becoming one of Oklahoma’s top five engineering consulting firms that we are today. Bob passed away in 2001, but his legacy continues through the work of our current president, Sam Pappas and Keith Angier, vice president.

Sam and Keith fuel the MAC vision through continued dedication to our community and producing quality work. Their work has proved successful in that the MAC Family has grown from just 14 employees in 2001 to more than 35 employees today.

MAC remains dedicated to centering our values around our fundamental principles: trust, integrity and unparalleled customer service. We attribute our continued success to the solid foundation Bob laid for us more than 40 years ago.
