Susan Merrill, who spent a total of six years as head of enforcement for the New York Stock Exchange regulatory arm and the entity that succeeded it, will join Bingham McCutchen‘s broker-dealer group in New York this week.

Merrill, 53, stepped down last month as chief of enforcement at the Financial Industry Regulatory Authority, a private corporation that regulates brokerage firms and trading markets. She spent three years at the New York Stock Exchange prior to joining FINRA in 2007 when the agency was created by the merger between NYSE’s regulatory group and the National Association of Securities Dealers. (The SEC approved the merger between the NASD and NYSE’s regulation group in July 2007.)
