Although partners Joel Goldberg and William Grant left Willkie Farr & Gallagher this year because they would turn 65, the firm’s mandatory retirement age, neither actually retired. Mr. Goldberg last month became a partner at Stroock & Stroock & Lavan, while Mr. Grant in February joined Winston & Strawn as senior counsel.

“I like what I do, I enjoy working, and I consider myself a young 64 at this point and don’t much want to play golf and sail all the time,” said Mr. Grant, who turns 65 this month.
