During the financial markets turmoil, William Sweet remained steady.

The leader of Skadden’s financial institutions regulatory and enforcement group, Sweet helped stabilize banks and keep investment money flowing. He shepherded a consortium of private-equity investors to create a newly chartered version of BankUnited Inc. after the 85-branch Florida bank was shut down by the Federal Deposit Insurance Corp. The deal served as the template for private-equity investors seeking to salvage banks under FDIC control. Justifiably — BankUnited today has $11 billion in assets and has completed a $900 million initial public offering.

Sweet has handled dozens of private equity acquisitions, including those with Pacific Capital Bancorp, First Southern Bancorp Inc., Korea Exchange Bank, American Stock Transfer & Trust Co. and many others.
