Barney practices law just like we do. We’ve worked together for years, and we know he will be an excellent addition to our group.”
“Barney is a standout lawyer in the financial services arena in London and beyond,” said John Horsfield-Bradbury, Managing Partner of S&C’s London office. “His addition will add first-rate UK regulatory capabilities to our leading position in the United States and reinforce our status as a top legal global advisor to financial institutions.

He helped numerous financial institutions during the 2008 financial crisis, the Eurozone crisis of 2009-2012, and more recently, the Credit Suisse and Silicon Valley Bank situations. Mr. Reynolds also designed the legal regime for the Abu Dhabi Global Market and led a team of lawyers in crafting its laws.
