Former U.S. Attorney Dexter Lehtinen and four other Tew Cardenas lawyers have split from the Miami law firm to open their own shop following the death of co-founder Thomas Tew.

The new firm, Lehtinen Schultz Riedi Catalano De la Fuente, opened at 1111 Brickell Ave., where the lawyers leased 1,300 square feet. The group includes Thomas Schultz, a former chair of the federal judicial nominating commission; Claudio Riedi; John Catalano; and Domingo Gamboa De La Fuente Jr. All are partners.
