Marc Mukasey and two other former shareholders from Greenberg Traurig announced Wednesday the official launch of their new boutique law firm in New York, Mukasey Frenchman & Sklaroff.

The announcement was not a surprise, as Mukasey left Greenberg at the end of January to launch the boutique. But the firm revealed new details in the launch announcement this week, including who else would be joining Mukasey, who had been co-chair of Greenberg Traurig's white-collar defense and investigations practice.

The boutique's partners include Mukasey, Robert Frenchman and Jeffrey Sklaroff. They will focus on white-collar matters, complex litigation and regulatory enforcement proceedings.
