ABOUT US
Founded in 1976 by the late Robert J. “Bob” MacArthur, PE, MacArthur Associated Consultants, LLC (MAC) was built on a commitment to excellence, integrity, and service. With a background in both the United States Air Force and the Oklahoma Air National Guard, Bob established the firm with a strong foundation in military and aviation engineering. Those values continue to shape our culture and approach today.
Over the past five decades, MAC has grown into a full-service civil engineering and surveying firm serving clients across Oklahoma and the Southwest. Headquartered in the Oklahoma City metro with a satellite office in Tulsa, our team of more than 40 professionals provides expertise in aviation, transportation, military planning and design, civil site development, surveying, construction administration, and infrastructure engineering.
MAC has supported projects at more than 50 military installations and completed hundreds of aviation and infrastructure projects throughout the region. Our long-standing relationships and high percentage of repeat clients reflect our dedication to responsive service, technical excellence, and practical solutions tailored to each client’s needs.
Today, guided by Bob MacArthur’s original vision, we continue to build a tradition of engineering excellence by delivering thoughtful, reliable solutions that strengthen communities, support critical infrastructure, and serve those who depend on it most.
