Several attorneys who left Nelson Brown about a year ago have sued the firm for recovery of allegedly unpaid bonuses.

Seven attorneys who left Nelson Brown Hamilton & Krekstein in February 2014 to launch the Berwyn, Pa., office of Lewis Brisbois Bisgaard & Smith filed suit against their former firm in the Montgomery County Court of Common Pleas on Feb. 6.

Lewis Brisbois attorney Lawrence D. Jackson is representing the plaintiffs, who include partners Christopher J. DiIenno and James E. Prendergast, as well as associates Sian Schafle, Kevin Dolan, Laura Rieben, Ryan Loughlin and Kathryn Mellinger. Jackson joined the Los Angeles-based Lewis Brisbois from Nelson Brown with the plaintiffs, although he did not join the suit.
