Law firm Cozen O'Connor has opened a Pittsburgh office with three lawyers who were formerly with Buchanan Ingersoll & Rooney, which has its headquarters in that city.

They are: labor and employment lawyer Thomas Giotto; corporate attorney Jeremy Garvey; and complex commercial and health-care litigator Gene Giotto.

Cozen said it expects a number of other lawyers will be joining the firm's Pittsburgh office in the coming months.
