For two Chicago litigators, a taste of life in a large law firm left them craving a return to the boutique model.

Robert Palmersheim and Anand Mathew have taken their practice from Detroit-based Am Law 200 firm Honigman Miller Schwartz and Cohn, and launched their own firm, Palmersheim & Mathew. The new litigation boutique, which officially launched Tuesday, will focus on complex business disputes for clients of various sizes, Mathew said.
