A plaintiff law firm based in Atlanta is splitting up, with one of the founding partners taking a four-lawyer group to products liability boutique Singleton Schreiber.

Danielle Ward Mason of Atlanta firm Bullock Ward Mason led the four-lawyer team to San Diego-based Singleton Schreiber last week. The team will initially focus on ongoing product liability lawsuits related to alleged cancer-causing chemicals from hair-relaxing products, said managing partner Gerald Singleton.
