Angelo Ciavarella, a corporate transactions tax partner, has left Katten Muchin Rosenman and rejoined his old firm Reed Smith, saying the growth of the corporate group attracted him.

Ciavarella helps private equity funds and other clients implement tax-efficient strategies on their deals, his firm said. He’d been a partner at Reed Smith until 2016, when he moved to Katten. But since then, he said, he remained friendly with Reed Smith’s corporate leader James Tandler, and the opportunity to move back eventually arose.
