John is a partner in our Risk Practice, working closely with McKinsey colleagues and clients on a variety of topics related to risk and regulation. He has extensive knowledge of regulation, the banking industry, monetary policy, and economics. He is based in Washington, DC.

Prior to joining McKinsey in 2012, John served as the acting Comptroller of the Currency from August 2010 until April 2012.
