While many planned events of 2020 have been postponed or modified, Pittsburgh-based Tucker Arensberg continued its plans to pass on the leadership torch this year.

Irving Firman, the new managing shareholder, took on that role as of Sept. 1. He took over for Thomas Peterson, who had been the firm’s managing partner since 2009, as Peterson returns full-time to his practice, which focuses on corporate, M&A and education law.
