His representations have been of a wide variety of clients, including public and privately held corporations, directors of such companies, individuals, and some of the largest financial institutions, both domestic and international.

Aaron was the lead trial counsel in the longest civil jury trial in the Federal Court of the Southern District of New York, lead counsel in the representation of mg technologies ag (now GEA Group AG), the German conglomerate, and its subsidiaries in numerous securities, shareholder derivative and derivatives-related actions arising out of mg’s nearly $2 billion of losses in derivatives contracts, and the lead trial counsel representing one of the largest state-owned corporations of the People’s Republic of China in a derivatives-related trial in the Southern District of New York.
