Mr. Middlemiss focuses on providing strategic counsel to foreign and domestic entities seeking to mitigate regulatory, criminal and reputational risk in the areas of anti-money laundering (AML) and anti-bribery and corruption (ABC). Mr. Middlemiss has represented individuals and corporations in criminal investigations, investigated alleged violations of the Foreign Corrupt Practices Act, and advised financial and other companies with respect to best practices in the fields of AML and ABC compliance. 

Prior to joining the firm, Mr. Middlemiss was the Director of the Global Anti-Corruption Program at JPMorgan Chase & Co, responsible for designing and executing an enterprise-wide compliance program to mitigate corruption-related risk. Mr. Middlemiss also held multiple senior positions in the bank’s Anti-Money Laundering Program. Among them, Mr. Middlemiss headed the firm’s Financial Intelligence Unit, a group formed to develop strategies to identify and confront proactively emergent money-laundering related risk, including that posed by human trafficking.
