Post & Schell has acquired three attorneys with leadership experience from Marks, O’Neill, O’Brien, Doherty & Kelly, in a move that occurred before the Philadelphia insurance defense firm lost 19 attorneys to Gordon Rees Scully Mansukhani in the first week of March.

Attorneys Michael Kosar and Michael Notartomas joined Post & Schell as principals in the firm’s casualty litigation department in its Mount Laurel, New Jersey, office, while Christian Scheuerman has joined as a principal in the firm’s professional liability department, operating out of its Philadelphia office. These moves occurred at the end of February.
