Independent advisors to global air transportation stakeholders, leveraging proprietary analytical tools and experienced practitioners.



GRA deeply regrets the passing of its founder, Dr. Aaron J Gellman.

Aaron had many prominent careers including as a professor at the Wharton School and Northwestern University, a senior executive in the railroad supply industry, an officer in the US Army where he helped to develop the container concept that now dominates world trade and as a consultant at GRA where he had many noteworthy clients including Federal Express, Control Data, NASA, the National Science Foundation, FAA and the Department of Transportation.

His PhD thesis at MIT made an important contribution by demonstrating linkages between regulation and technological change in commercial aircraft markets.

Aaron was a true visionary and guiding light for an entire generation of his colleagues including those privileged to work with him at the firm he founded in 1973.

We will miss him.
