Ballard Spahr litigation partner Mark. S. Stewart will take over as firm Chair on July 1. He will replace Arthur Makadon, who will return to the full-time practice of law after leading the firm since 2002.

Mr. Stewart will be the firm’s first full-time chairman. "The partners seemed to think that the firm was ready for a full-time chairman," Mr. Stewart said. "I will do more traveling, and I will spend more time away from Philadelphia."
