Sonnenschein Nath & Rosenthal just opened its first office in Phoenix with a group of hospitality and real estate attorneys from Squire, Sanders & Dempsey.

Richard Ross, who is leading the exodus from Squire Sanders, said the group started Wednesday at Sonnenschein. Seven lawyers, including three partners, are joining the firm in Phoenix and three lawyers, including one partner, are headed for Sonnenschein’s Washington, D.C., office.
