Therese Doherty, head of the securities, futures and derivatives litigation practice at Herrick, Feinstein in New York, is headed to Mintz, Levin, Cohn, Ferris, Glovsky and Popeo. Her move to Mintz Levin comes a month after the firm ended merger talks with Crowell & Moring.

In heading to Mintz Levin, Doherty re-joins former Herrick colleague Christopher Sullivan, a former executive committee member at the firm who decamped for Mintz Levin in early March. She takes with her Herrick litigation associate LisaMarie Collins, who is joining Mintz Levin as of counsel.

“I don't [change law firms] very often, but Mintz Levin has a stellar reputation and a little bit of a deeper litigation bench,” said Doherty, who spent the past 16 years at Herrick, a firm she joined in 2001 from what is now called Graubard Miller.
