A crowded field is vying for the top management spot at McDermott, Will & Emery. Five partners from as many offices are seeking to be the firm’s next chairman in an election scheduled to be held Thursday.

In June, Jeffrey Stone and Peter Sacripanti, who have led McDermott for eight years as co-chairmen, abruptly announced that they would step down at the end of this year. Three months earlier, the two litigation partners had been elected to another one-year term and had unveiled a new five-year strategic plan. “We thought it was an appropriate time to make a transition,” Stone said at the time. “We have a deep bench of people to step up on the leadership ranks.”
